Lipedema: Current Diagnostic and Treatment Evidence
Lipedema affects about 11% of cisgender women, according to the Brazilian Society of Angiology and Vascular Surgery. Yet the condition remains wrapped in uncertainties. Despite significant advancements in understanding its physiology, diagnosis, and treatment, more clarity is needed as awareness and diagnoses increase.
At the latest International Congress on Obesity (ICO) in São Paulo, Brazil, Philipp Scherer, PhD, director of the Touchstone Diabetes Center, discussed the complexities of lipedema. “It is an extremely frustrating condition for someone like me, who has spent a lifetime studying functional and dysfunctional adipose tissue. We are trying to understand the physiology of this pathology, but it is challenging, and so far, we have not been able to find a concrete answer,” he noted.
Lipedema is characterized by the abnormal accumulation of subcutaneous adipose tissue, especially in the lower limbs, and almost exclusively affects cisgender women. The reason for this gender disparity is unclear. It could be an intrinsic characteristic of the disease or a result from clinicians’ lack of familiarity with lipedema, which often leads to misdiagnosis as obesity. This misdiagnosis results in fewer men seeking treatment.
Research has predominantly focused on women, and evidence suggests that hormones play a crucial role in the disease’s pathophysiology. Lipedema typically manifests during periods of hormonal changes, such as puberty, pregnancy, menopause, and hormone replacement therapies, reinforcing the idea that hormones significantly influence the condition’s development and progression.
Main Symptoms
Jonathan Kartt, CEO of the Lipedema Foundation, emphasized that intense pain in the areas of adipose tissue accumulation is a hallmark symptom of lipedema, setting it apart from obesity. Pain levels can vary widely among patients, ranging from moderate to severe, with unbearable peaks on certain days. Mr. Kartt stressed the importance of recognizing and addressing this often underestimated symptom.
Lipedema is characterized by a bilateral, symmetrical increase in mass compared with the rest of the body. This is commonly distinguished by the “cuff sign,” a separation between normal tissue in the feet and abnormal tissue from the ankle upward. Other frequent symptoms include a feeling of heaviness, discomfort, fatigue, frequent bruising, and tiredness. A notable sign is the presence of subcutaneous nodules with a texture similar to that of rice grains, which are crucial for differentiating lipedema from other conditions. Palpation during anamnesis is essential to identify these nodules and confirm the diagnosis.
“It is crucial to investigate the family history for genetic predisposition. Additionally, it is fundamental to ask whether, even with weight loss, the affected areas retain accumulated fat. Hormonal changes, pain symptoms, and impact on quality of life should also be carefully evaluated,” advised Mr. Kartt.
Diagnostic Tools
André Murad, MD, a clinical consultant at the Instituto Lipedema Brazil, has been exploring new diagnostic approaches for lipedema beyond traditional anamnesis. During his presentation at the ICO, he shared studies on the efficacy of imaging exams such as ultrasound, tomography, and MRI in diagnosing the characteristic lipedema-associated increase in subcutaneous tissue.
He also discussed lymphangiography and lymphoscintigraphy, highlighting the use of magnetic resonance lymphangiography to evaluate dilated lymphatic vessels often observed in patients with lipedema. “By injecting contrast into the feet, this technique allows the evaluation of vessels, which are usually dilated, indicating characteristic lymphatic system overload in lipedema. Lymphoscintigraphy is crucial for detecting associated lymphedema, revealing delayed lymphatic flow and asymmetry between limbs in cases of lipedema without lymphedema,” he explained.
Despite the various diagnostic options, Dr. Murad highlighted two highly effective studies. A Brazilian study used ultrasound to establish a cutoff point of 11.7 mm in the pretibial subcutaneous tissue thickness, achieving 96% specificity for diagnosis. Another study emphasized the value of dual-energy x-ray absorptiometry (DXA), which demonstrated 95% sensitivity. This method assesses fat distribution by correlating the amount present in the legs with the total body, providing a cost-effective and accessible option for specialists.
“DXA allows for a precise mathematical evaluation of fat distribution relative to the total body. A ratio of 0.38 in the leg-to-body relationship is a significant indicator of high suspicion of lipedema,” highlighted Dr. Murad. “In clinical practice, many patients self-diagnose with lipedema, but the clinical exam often reveals no disproportion, with the leg-to-body ratio below 0.38 being common in these cases,” he added.
Treatment Approaches
Treatments for lipedema are still evolving, with considerable debate about the best approach. While some specialists advocate exclusively for conservative treatment, others recommend combining these methods with surgical interventions, depending on the stage of the disease. The relative novelty of lipedema and the scarcity of robust, long-term studies contribute to the uncertainty around treatment efficacy.
Conservative treatment typically includes compression, lymphatic drainage techniques, and pressure therapy. An active lifestyle and a healthy diet are also recommended. Although these measures do not prevent the accumulation of adipose tissue, they help reduce inflammation and improve quality of life. “Even though the causes of lipedema are not fully known, lifestyle management is essential for controlling symptoms, starting with an anti-inflammatory diet,” emphasized Dr. Murad.
Because insulin promotes lipogenesis, a diet that avoids spikes in glycemic and insulin levels is advisable. Insulin resistance can exacerbate edema formation, so a Mediterranean diet may be beneficial. This diet limits fast-absorbing carbohydrates, such as added sugar, refined grains, and ultraprocessed foods, while promoting complex carbohydrates from whole grains and legumes.
Dr. Murad also presented a study evaluating the potential benefits of a low-carbohydrate, high-fat diet for patients with lipedema. The study demonstrated weight loss, reduced body fat, controlled leg volume, and, notably, pain relief.
For more advanced stages of lipedema, plastic surgery is often considered when conservative approaches do not yield satisfactory results. Some specialists advocate for surgery as an effective way to remove diseased adipose cells and reduce excess fat accumulation, which can improve physical appearance and associated pain. There is a growing consensus that surgical intervention should be performed early, ideally in stage I of IV, to maximize efficacy and prevent disease progression.
Fábio Masato Kamamoto, MD, a plastic surgeon and director of the Instituto Lipedema Brazil, shared insights into surgical treatments for lipedema. He discussed techniques from liposuction to advanced skin retraction and dermolipectomy, crucial for addressing more advanced stages of the condition. “It’s a complex process that demands precision to protect the lymphatic system, especially considering the characteristic nodules of lipedema,” he noted.
Dr. Kamamoto discussed a former patient with stage III lipedema. In the initial stage, he performed liposuction, removing 8 L of fat and 3.4 kg of skin. After 6 months, a follow-up procedure resulted in a total removal of 15 kg. Complementary procedures, such as microneedling, were performed to stimulate collagen production and reduce skin sagging. In addition to cosmetic improvements, the procedure also removed the distinctive lipedema nodules, which Mr. Kartt described as feeling like “rice grains.” Removing these nodules significantly alleviates pain, according to Dr. Kamamoto.
The benefits of surgical treatment for lipedema can be long lasting. Dr. Kamamoto noted that fat tends not to reaccumulate in treated areas, with patients often experiencing lower weight, reduced edema, and decreased pain over time. “While we hope that patients do not regain weight, the benefits of surgery persist even if weight is regained. Therefore, combining conservative and surgical treatments remains a valid and effective approach,” he concluded.
Dr. Scherer highlighted that despite various approaches, there is still no definitive “magic signature” that fully explains lipedema. This lack of clarity directly affects the effectiveness of diagnoses and treatments. He expressed hope that future integration of data from different studies and approaches will lead to the identification of a clinically useful molecular signature. “The true cause of lipedema remains unknown, requiring more speculation, hypothesis formulation, and testing for significant discoveries. This situation is frustrating, as the disease affects many women who lack a clear diagnosis that differentiates them from patients with obesity, as well as evidence-based recommendations,” he concluded.

Safety Standards a Top Priority for ASLMS President
Arisa E. Ortiz, MD, began her term as president of the American Society for Laser Medicine and Surgery (ASLMS) during the organization’s annual meeting in April 2024.
After earning her medical degree from Albany Medical College, Albany, New York, Dr. Ortiz, a native of Los Angeles, completed her dermatology residency training at the University of California, Irvine, and the university’s Beckman Laser Institute. Next, she completed a laser and cosmetic dermatology fellowship at Massachusetts General Hospital, Harvard Medical School, and the Wellman Center for Photomedicine, all in Boston, and acquired additional fellowship training in Mohs micrographic surgery at the University of California, San Diego (UCSD). Dr. Ortiz is currently director of laser and cosmetic dermatology and a clinical professor of dermatology at UCSD.
She has authored more than 60 publications on new innovations in cutaneous surgery and is a frequent speaker at meetings of the American Academy of Dermatology, the American Society for Dermatologic Surgery (ASDS), and ASLMS, and she cochairs the annual Masters of Aesthetics Symposium in San Diego. Dr. Ortiz has received several awards, including the 2024 Castle Connolly Top Doctor Award and the Exceptional Women in Medicine Award; Newsweek America’s Best Dermatologists; the ASLMS Dr. Horace Furumoto Young Investigator Award, the ASLMS Best of Session Award for Cutaneous Applications, and the ASDS President’s Outstanding Service Award. Her primary research focuses on the laser treatment of nonmelanoma skin cancer.
In an interview, Dr. Ortiz spoke about her goals as ASLMS president and other topics related to dermatology.
Who inspired you most to become a doctor?
I’ve wanted to become a doctor for as long as I can remember. My fascination with science and the idea of helping people improve their health were driving forces. However, my biggest influence early on was my uncle, who was a pediatrician. His dedication and passion for medicine deeply inspired me and solidified my desire to pursue a career in healthcare.
I understand that a bout with chickenpox as a teenager influenced your decision to specialize in dermatology.
It’s an interesting and somewhat humorous story. When I was 18, I contracted chickenpox and ended up with scars on my face. It was a tough experience as a teenager, but it’s fascinating how such events can shape your life. In my quest for help, I opened the Yellow Pages and randomly chose a dermatologist nearby, who turned out to be Gary Lask, MD, director of lasers at UCLA [University of California, Los Angeles]. During our visit, I mentioned that I was premed, and he encouraged me to consider dermatology. About 6 years later, as a second-year medical student, I realized my passion for dermatology. I reached out to Dr. Lask and told him: “You were right. I want to be a dermatologist. Now, you have to help me get in!” Today, he remains my mentor, and I am deeply grateful for his guidance and support on this journey.
One of the initiatives for your term as ASLMS president includes a focus on safety standards for lasers and energy-based devices. Why is this important now?
Working at the university, I frequently encounter severe complications arising from the improper use of lasers and energy-based devices. As these procedures gain popularity, more providers are offering them, yet often without adequate training. As the world’s premier laser society, it is our duty to ensure patient safety. In the ever-evolving field of laser medicine, it is crucial that we continually strive to enhance the regulation of laser usage, ensuring that patients receive the highest standard of care with minimal risk.
One of the suggestions you have for the safety initiative is to offer a rigorous laser safety certification course with continuing education opportunities as a way foster a culture of heightened safety standards. Please explain what would be included in such a course and how it would align with current efforts to report adverse events such as the ASDS-Northwestern University Cutaneous Procedures Adverse Events Reporting (CAPER) registry and the Food and Drug Administration’s MedWatch Program.
A laser safety certification task force has been established to determine the best approach for developing a comprehensive course. The task force aims to assess the necessity of a formal safety certification in our industry, identify the resources needed to support such a certification, establish general safety protocols to form the content foundation, address potential legal concerns, and outline the process for formal certification program recognition. This exploratory work is expected to conclude by the end of the year. The proposed course may include modules on the fundamentals of laser physics, safe operation techniques, patient selection and management, and emergency protocols. Continuing education opportunities would be considered to keep practitioners updated on the latest advancements and safety protocols in laser medicine, thereby fostering a culture of heightened safety standards.
Another initiative for your term is the rollout of a tattoo removal program for former gang members based on the UCSD Clean Slate Tattoo Removal Program. Please tell us more about your vision for this national program.
UCSD Dermatology, in collaboration with UCSD Global Health, has been involved in the Clean Slate Tattoo Removal Program for the past decade. This initiative supports and rehabilitates former gang members by offering laser tattoo removal, helping them reintegrate into society. My vision is to equip our members with the necessary protocols to implement this outreach initiative in their own communities. By providing opportunities for reform and growth, we aim to foster safer and more inclusive communities nationwide.
You were one of the first clinicians to use a laser to treat basal cell carcinoma (BCC). Who are the ideal candidates for this procedure? Is the technique ready for wide clinical adoption? If not, what kind of studies are needed to make it so?
My research passion lies in optimizing laser treatments for BCC. During my fellowship with R. Rox Anderson, MD, and Mathew Avram, MD, at the MGH Wellman Center for Photomedicine, we conducted a pilot study using the 1064-nm Nd:YAG laser, achieving a 92% clearance rate after one treatment. Inspired by these results, we conducted a larger multicenter study, which demonstrated a 90% clearance rate after a single treatment. I now incorporate this technique into my daily practice. The ideal candidates for this procedure are patients with BCC that do not meet the Mohs Appropriate Use Criteria, such as those with nodular or superficial BCC subtypes on the body, individuals who are poor surgical candidates, or those who are surgically exhausted. However, I do not recommend this treatment for patients who are primarily concerned about facial scarring, particularly younger individuals; in such cases, Mohs surgery still remains the preferred option. While I believe this technique is ready for broader clinical adoption, it requires an understanding of laser endpoints. We are also exploring antibody-targeted gold nanorods to enhance the selectivity and standardization of the treatment.
Who inspires you most in your work today?
My patients are my greatest inspiration. Their trust and dedication motivate me to stay at the forefront of dermatologic advancements, ensuring I provide the most cutting-edge and safe treatments possible. Their commitment drives my relentless pursuit of continuous learning and innovation in the field.
What’s the best advice you can give to female dermatologists seeking leadership positions at the local, state, or national level?
My best advice is to have the courage to ask for what you seek. Societies are always looking for members who are eager to participate and contribute. If you express your interest in becoming more involved, there is likely a position available for you. The more you are willing to contribute to a society, the more likely you will be noticed and excel into higher leadership positions. Take initiative, show your commitment, and don’t hesitate to step forward when opportunities arise.
What’s the one tried-and-true laser- or energy-based procedure that you consider a “must” for your dermatology practice? And why?
Determining a single “must-have” laser- or energy-based procedure is a challenging question as it greatly depends on the specific needs of your patient population. However, one of the most common concerns among patients involves issues like redness and pigmentation. Therefore, having a versatile laser or an intense pulsed light device that effectively targets both red and brown pigmentation is indispensable for most practices.
In your view, what are the top three trends in aesthetic dermatology?
Over the years, I have observed several key trends in aesthetic dermatology:
- Minimally invasive procedures. There is a growing preference for less invasive treatments. Patients increasingly desire minimal downtime while still achieving significant results.
- Advancements in laser and energy-based devices for darker skin. There have been substantial advancements in technologies that are safer and more effective for darker skin tones. These developments play a crucial role in addressing diverse patient needs and providing inclusive dermatologic care.
- Natural aesthetic. I am hopeful that the trend toward an overdone appearance is fading. There seems to be a shift back towards a more natural and conservative aesthetic, emphasizing subtle enhancements over dramatic changes.
What development in dermatology are you most excited about in the next 5 years?
I am most excited to see how artificial intelligence and robotics play a role in energy-based devices.

During our visit, I mentioned that I was premed, and he encouraged me to consider dermatology. About 6 years later, as a second-year medical student, I realized my passion for dermatology. I reached out to Dr. Lask and told him: “You were right. I want to be a dermatologist. Now, you have to help me get in!” Today, he remains my mentor, and I am deeply grateful for his guidance and support on this journey.
One of the initiatives for your term as ASLMS president includes a focus on safety standards for lasers and energy-based devices. Why is this important now?
Working at the university, I frequently encounter severe complications arising from the improper use of lasers and energy-based devices. As these procedures gain popularity, more providers are offering them, yet often without adequate training. As the world’s premier laser society, it is our duty to ensure patient safety. In the ever-evolving field of laser medicine, it is crucial that we continually strive to enhance the regulation of laser usage, ensuring that patients receive the highest standard of care with minimal risk.
One of the suggestions you have for the safety initiative is to offer a rigorous laser safety certification course with continuing education opportunities as a way foster a culture of heightened safety standards. Please explain what would be included in such a course and how it would align with current efforts to report adverse events such as the ASDS-Northwestern University Cutaneous Procedures Adverse Events Reporting (CAPER) registry and the Food and Drug Administration’s MedWatch Program.
A laser safety certification task force has been established to determine the best approach for developing a comprehensive course. The task force aims to assess the necessity of a formal safety certification in our industry, identify the resources needed to support such a certification, establish general safety protocols to form the content foundation, address potential legal concerns, and outline the process for formal certification program recognition. This exploratory work is expected to conclude by the end of the year. The proposed course may include modules on the fundamentals of laser physics, safe operation techniques, patient selection and management, and emergency protocols. Continuing education opportunities would be considered to keep practitioners updated on the latest advancements and safety protocols in laser medicine, thereby fostering a culture of heightened safety standards.
Another initiative for your term is the rollout of a tattoo removal program for former gang members based on the UCSD Clean Slate Tattoo Removal Program. Please tell us more about your vision for this national program.
UCSD Dermatology, in collaboration with UCSD Global Health, has been involved in the Clean Slate Tattoo Removal Program for the past decade. This initiative supports and rehabilitates former gang members by offering laser tattoo removal, helping them reintegrate into society. My vision is to equip our members with the necessary protocols to implement this outreach initiative in their own communities. By providing opportunities for reform and growth, we aim to foster safer and more inclusive communities nationwide.
You were one of the first clinicians to use a laser to treat basal cell carcinoma (BCC). Who are the ideal candidates for this procedure? Is the technique ready for wide clinical adoption? If not, what kind of studies are needed to make it so?
My research passion lies in optimizing laser treatments for BCC. During my fellowship with R. Rox Anderson, MD, and Mathew Avram, MD, at the MGH Wellman Center for Photomedicine, we conducted a pilot study using the 1064-nm Nd:YAG laser, achieving a 92% clearance rate after one treatment. Inspired by these results, we conducted a larger multicenter study, which demonstrated a 90% clearance rate after a single treatment. I now incorporate this technique into my daily practice. The ideal candidates for this procedure are patients with BCC that do not meet the Mohs Appropriate Use Criteria, such as those with nodular or superficial BCC subtypes on the body, individuals who are poor surgical candidates, or those who are surgically exhausted. However, I do not recommend this treatment for patients who are primarily concerned about facial scarring, particularly younger individuals; in such cases, Mohs surgery still remains the preferred option. While I believe this technique is ready for broader clinical adoption, it requires an understanding of laser endpoints. We are also exploring antibody-targeted gold nanorods to enhance the selectivity and standardization of the treatment.
Who inspires you most in your work today?
My patients are my greatest inspiration. Their trust and dedication motivate me to stay at the forefront of dermatologic advancements, ensuring I provide the most cutting-edge and safe treatments possible. Their commitment drives my relentless pursuit of continuous learning and innovation in the field.
What’s the best advice you can give to female dermatologists seeking leadership positions at the local, state, or national level?
My best advice is to have the courage to ask for what you seek. Societies are always looking for members who are eager to participate and contribute. If you express your interest in becoming more involved, there is likely a position available for you. The more you are willing to contribute to a society, the more likely you will be noticed and excel into higher leadership positions. Take initiative, show your commitment, and don’t hesitate to step forward when opportunities arise.
What’s the one tried-and-true laser- or energy-based procedure that you consider a “must” for your dermatology practice? And why?
Determining a single “must-have” laser- or energy-based procedure is a challenging question as it greatly depends on the specific needs of your patient population. However, one of the most common concerns among patients involves issues like redness and pigmentation. Therefore, having a versatile laser or an intense pulsed light device that effectively targets both red and brown pigmentation is indispensable for most practices.
In your view, what are the top three trends in aesthetic dermatology?
Over the years, I have observed several key trends in aesthetic dermatology:
- Minimally invasive procedures. There is a growing preference for less invasive treatments. Patients increasingly desire minimal downtime while still achieving significant results.
- Advancements in laser and energy-based devices for darker skin. There have been substantial advancements in technologies that are safer and more effective for darker skin tones. These developments play a crucial role in addressing diverse patient needs and providing inclusive dermatologic care.
- Natural aesthetic. I am hopeful that the trend toward an overdone appearance is fading. There seems to be a shift back towards a more natural and conservative aesthetic, emphasizing subtle enhancements over dramatic changes.
What development in dermatology are you most excited about in the next 5 years?
I am most excited to see how artificial intelligence and robotics play a role in energy-based devices.

I understand that a bout with chickenpox as a teenager influenced your decision to specialize in dermatology.
It’s an interesting and somewhat humorous story. When I was 18, I contracted chickenpox and ended up with scars on my face. It was a tough experience as a teenager, but it’s fascinating how such events can shape your life. In my quest for help, I opened the Yellow Pages and randomly chose a dermatologist nearby, who turned out to be Gary Lask, MD, director of lasers at UCLA [University of California, Los Angeles].

Gluconolactone
This derivative of oxidized glucose lactone is present naturally in bread, cheese, fruit juices, honey, tofu, and wine, and is used as a food additive in Europe.1,2 In dermatology, it is most often used in chemical peels.
Polyhydroxy acids (PHAs) were discovered about 3 decades ago to exert similar functions as alpha hydroxy acids without provoking sensory irritation reactions. Gluconolactone along with lactobionic acid were the identified PHAs and further characterized as delivering more humectant and moisturizing activity than alpha hydroxy acids and effective in combination with retinoic acid to treat adult acne and with retinyl acetate to confer antiaging benefits.3 It is typically added to products for its skin-conditioning qualities, resulting in smoother, brighter, more toned skin.4 This column focuses on recent studies using this bioactive agent for dermatologic purposes.
Split-Face Studies Show Various Benefits
In 2023, Jarząbek-Perz and colleagues conducted a split-face evaluation to assess the effects on various skin parameters (ie, hydration, pH, sebum, and transepidermal water loss [TEWL]) of gluconolactone and oxybrasion, compared with gluconolactone and microneedling. Twenty-one White women underwent a series of three split-face treatments at 1-week intervals. Chemical peels with 10% gluconolactone were performed on the whole face. The right side of the face was also treated with oxybrasion and the left with microneedle mesotherapy. Skin parameters were measured before the first and third treatments and 2 weeks following the final treatment. Photos were taken before and after the study. Both treatments resulted in improved hydration and reductions in sebum, pH, and TEWL. No statistically significant differences were noted between the treatment protocols. The researchers concluded that gluconolactone peels can be effectively combined with oxybrasion or microneedle mesotherapy to enhance skin hydration and to secure the hydrolipid barrier.5
Later that year, the same team evaluated pH, sebum levels, and TEWL before, during, and after several applications of 10% and 30% gluconolactone chemical peels in a split-face model in 16 female participants. The investigators conducted three procedures on both sides of the face, taking measurements on the forehead, periorbital area, on the cheek, and on the nose wing before, during, and 7 days after the final treatment. They found statistically significant improvements in sebum levels in the cheeks after the treatment series. Also, pH values were lower at each measurement site after each procedure. TEWL levels were significantly diminished around the eyes, as well as the left forehead and right cheek, with no significant discrepancy between gluconolactone concentrations. The researchers concluded that gluconolactone plays a major role in reducing cutaneous pH and TEWL and imparts a regulatory effect on sebum.1
Two years earlier, Jarząbek-Perz and colleagues assessed skin moisture in a split-face model in 16 healthy women after the application of 10% and 30% gluconolactone. Investigators measured skin moisture before and after each of three treatments and a week after the final treatment from the forehead, periorbital area, and on the cheek. They observed no significant discrepancies between the 10% and 30% formulations, but a significant elevation in facial skin hydration was found to be promoted by gluconolactone. The investigators concluded that gluconolactone is an effective moisturizer for care of dry skin.6
Topical Formulation
In 2023, Zerbinati and colleagues determined that a gluconolactone-based lotion that they had begun testing 2 years earlier was safe and effective for dermatologic applications, with the noncomedogenic formulation found suitable as an antiaging agent, particularly as it treats aging-related pore dilatation.7,8
Acne Treatment
In 2019, Kantikosum and colleagues conducted a double-blind, within-person comparative study to assess the efficacy of various cosmeceutical ingredients, including gluconolactone, glycolic acid, licochalcone A, and salicylic acid, combined with the acne treatment adapalene vs adapalene monotherapy for mild to moderate acne. Each of 25 subjects over 28 days applied a product mixed with 0.1% adapalene on one side of the face, and 0.1% adapalene alone on the other side of the face once nightly. The VISIA camera system spot score pointed to a statistically significant improvement on the combination sides. Differences in lesion reduction and severity were within acceptable margins, the authors reported. They concluded that the cosmeceutical combinations yielded similar benefits as adapalene alone, with the combination formulations decreasing acne complications.9
Potential Use as an Antifibrotic Agent
In 2018, Jayamani and colleagues investigated the antifibrotic characteristics of glucono-delta-lactone, a known acidifier, to ascertain if it could directly suppress collagen fibrils or even cause them to disintegrate. The researchers noted that collagen fibrillation is pH dependent, and that glucono-delta-lactone was found to exert a concentration-dependent suppression of fibrils and disintegration of preformed collagen fibrils with the antifibrotic function of the compound ascribed to its capacity to decrease pH. Further, glucono-delta-lactone appeared to emerge as an ideal antifibrotic agent as it left intact the triple helical structure of collagen after treatment. The investigators concluded that glucono-delta-lactone provides the foundation for developing antifibrotic agents intended to treat disorders characterized by collagen deposition.10
Conclusion
Gluconolactone emerged in the 1990s as a PHA useful in skin peels as an alternative to alpha hydroxy acids because of its nonirritating qualities. Since then, its soothing, hydrating, and, in particular, antiacne and antiaging qualities have become established. Wider applications of this versatile agent for dermatologic purposes are likely to be further investigated.

Each of 25 subjects over 28 days applied a product mixed with 0.1% adapalene on one side of the face, and 0.1% adapalene alone on the other side of the face once nightly. The VISIA camera system spot score pointed to a statistically significant improvement on the combination sides. Differences in lesion reduction and severity were within acceptable margins, the authors reported. They concluded that the cosmeceutical combinations yielded similar benefits as adapalene alone, with the combination formulations decreasing acne complications.9
Potential Use as an Antifibrotic Agent
In 2018, Jayamani and colleagues investigated the antifibrotic characteristics of glucono-delta-lactone, a known acidifier, to ascertain if it could directly suppress collagen fibrils or even cause them to disintegrate. The researchers noted that collagen fibrillation is pH dependent, and that glucono-delta-lactone was found to exert a concentration-dependent suppression of fibrils and disintegration of preformed collagen fibrils with the antifibrotic function of the compound ascribed to its capacity to decrease pH. Further, glucono-delta-lactone appeared to emerge as an ideal antifibrotic agent as it left intact the triple helical structure of collagen after treatment. The investigators concluded that glucono-delta-lactone provides the foundation for developing antifibrotic agents intended to treat disorders characterized by collagen deposition.10
Conclusion
Gluconolactone emerged in the 1990s as a PHA useful in skin peels as an alternative to alpha hydroxy acids because of its nonirritating qualities. Since then, its soothing, hydrating, and, in particular, antiacne and antiaging qualities have become established. Wider applications of this versatile agent for dermatologic purposes are likely to be further investigated.

More Illnesses Possible Related Linked to Counterfeit Botulinum Toxin Reported
— two in the intensive care unit. None of the cases required intubation, according to an announcement of an investigation into these reports in by the Centers for Disease Control and Prevention (CDC).
The report, published online in the Morbidity and Mortality Weekly Report, notes that the four patients in Tennessee received counterfeit BoNT, while product information was not available for the three cases in New York City. “However, one person reported paying less than US wholesale acquisition cost for the administered product, and another reported that the product had been purchased overseas,” the authors of the report wrote. The development underscores that BoNT injections “should be administered only by licensed and trained providers using recommended doses of FDA [Food and Drug Admininstration]-approved products.”
This report follows a CDC advisory published in April 2024 of at least 22 people from 11 states who reported serious reactions after receiving botulinum toxin injections from unlicensed or untrained individuals or in nonhealthcare settings, such as homes and spas.
The median age of the women in the July report was 48 years, and signs and symptoms included ptosis, dry mouth, dysphagia, shortness of breath, and weakness. Onset occurred between February 23 and March 7, 2024.
“This investigation did not determine why these illnesses occurred after cosmetic BoNT injections; potential reasons might include use of counterfeit BoNT, which might be more potent or contain harmful additional ingredients or higher susceptibility to BoNT effects among some persons,” the investigators wrote. They recommended further studies to describe the clinical spectrum of cosmetic BoNT injection effects such as severity of signs and symptoms.
For cases of suspected systemic botulism, the CDC recommends calling the local or state health department for consultation and antitoxin release (as well as information on reporting adverse events). Alternatively, the 24/7 phone number for the CDC clinical botulism service is 770-488-7100.

How Dermatologists Can Safeguard Against Malpractice Claims
for liability. Dermatologists can protect themselves by understanding malpractice trends and taking preventive steps, such as making sure NPOs have appropriate training and using a rigorous informed consent process, according to a dermatology resident and a dermatologist who have researched recent trends in dermatology lawsuits.
“It’s really important that physicians recognize their responsibility when delegating procedures to nonphysician operators and the physician’s role in supervision of these procedures,” Scott Stratman, MD, MPH, a dermatology resident at the Icahn School of Medicine at Mount Sinai, New York City, told this news organization. He led a study recently published in the Journal of the American Academy of Dermatology, which found that the majority (52%) of malpractice cases for cutaneous energy-based device procedures in the LexisNexis database from 1985 to September 2023 involved NPOs. The study did not break the data down between different types of NPOs.
Trends in Dermatology Malpractice
This follows a similar trend reported in a 2014 study led by Mathew M. Avram, MD, JD, director of the MGH Dermatology Laser and Cosmetic Center at Massachusetts General Hospital, Boston. The study analyzed liability claims related to cutaneous laser surgery performed by nonphysicians from January 1999 to December 2012.
“With nonphysician litigation data, we saw trend lines beginning in 2008 where the proportion of cases began to increase,” Dr. Avram said at the American Society for Laser Medicine and Surgery (ASLMS) meeting on April 12, 2024. “Over a period of 2008-2012, it went from 36% of cases to about 78%,” he said.
About a quarter (23.4%) of those were in medical offices; 76.6% were in nontraditional settings such as medical spas, he added. The proportion of NPOs was similar in a 2022 study that looked at causes of litigation in cutaneous laser surgery from 2012 to 2020, Dr. Avram said. Again, neither study broke down cases involving NPOs by specific type, but the 2014 study reported that 64% of cases by NPOs occurred outside of a traditional medical setting.
“So it seems that the location and potentially the supervision are issues that are important to patient safety,” Dr. Avram said at the meeting. While state laws regarding laser delegation vary widely, “depending on where you practice, it’s incumbent upon you to know that.”
Dr. Avram and colleagues were also the authors of a study published in June in Dermatologic Surgery that looked at the reasons behind ligations involving dermatologists in a retrospective analysis of 48 state and federal cases between 2011 and 2022. The majority of cases — 54.2% — were for unexpected harm, followed by wrong or delayed diagnoses, which accounted for a third of litigations.
Dr. Stratman’s study found that laser hair removal was the most common procedure for malpractice claims in dermatology among cutaneous energy-based device procedures. Complications from energy-based devices included burns, scarring, and pigmentation changes.
The growth of malpractice suits involving NPOs could be because NPOs are performing a greater proportion of dermatologic procedures, “particularly those practicing without direct supervision, such as in the context of a medical spa,” Dr. Stratman said in the interview. “Again, this highlights a physician’s responsibility in delegating these kinds of procedures to NPOs.”
Training Is a Must — But Not Standardized
Comprehensive training for physicians, staff, NPOs, and physicians “is all necessary and paramount in order to diminish adverse outcomes and legal risk, and then, of course, all these practitioners, be it staff or [NPOs], and, of course, physicians, are all held to the same standard of care,” Dr. Stratman said.
However, he added, “There is really no standardized training to operate these devices. That being said, it’s really important to know that both providers and facility owners have a significant obligation to their patients to make sure that their staff in their centers are appropriately trained.”
Training not only involves protocols and procedures but also how to handle patient interactions, Dr. Stratman said.
The legal concept of respondeat superior applies when nonphysicians participate in a patient’s care, Dr. Avram said at the ASLMS meeting. The physician is held liable for a nonphysician’s “negligence provided he or she is an employee receiving a salary [and] benefits and is performing within the scope of his or her duty,” regardless of whether the physician saw the patient or not at that visit, he said. Again, supervision of nonphysician laser procedures varies from state to state, he added.
“So the take-home point is to provide excellent training and appropriate supervision, and if you’re the owner of that practice, you are liable in the event of negligence even though you never were part of the treatment,” Dr. Avram said.
Ins and Outs of Informed Consent
When a patient outcome is less than desirable, or at least less than what the patient expected, a transparent and thorough informed consent process can protect the practice and physician, Dr. Avram said at the meeting.
“Malpractice and consent have nothing to do with each other,” he said. “Consent is getting permission to do a procedure. It’s needed actually for any medical intervention that you perform. What you need to do is to provide information to enable the patient or guardian or to choose knowledgeably among reasonable medical alternatives. This places the patient in control of the course of their medical treatment.”
The information conveyed to the patient should include the diagnosis, the medical causes, the nature and purpose of the treatment, and the risks and alternatives of procedure, “particularly if they’re high risk,” Dr. Avram said.
“Failure to obtain informed consent constitutes a civil battery, and the physician is liable for civil damages,” he said. “The patient need only show that he or she was not informed of the medical nature of the medical touching; physical injury is not necessary.”
A battery could occur if a procedure extends beyond the scope or area of treatment the patient agreed to — for example, extending a liposuction to an area that wasn’t originally targeted, or extending a laser procedure to an area of the body as a presumed favor to the patient. “It does not require a standard of care or an expert witness,” Dr. Avram said. “One only needs to show nonconsensual touching.”
Informed consents should include plain language, he said. “The whole idea is the patient understands what the risks and benefits are,” Dr. Avram said. “You don’t need to use medical jargon.” As an example, he suggested using the term “blisters” instead of “bullae.” If the treatment involves an off-label procedure, include that too, he said.
He also advised avoiding blanket authorizations. “Courts disfavor them,” he noted. “They need more specificity. So those are not valid.”
Dr. Stratman added that providers should think about the setting in which they obtain informed consent. “It’s really important that providers are consenting their patients in private and quiet places, free from distractions, that they accommodate patients who might have disabilities or limitations in English proficiency, using a teach-back method to help patients understand or demonstrate their understanding of the procedure in order to gauge comprehension,” he said.
Both Dr. Avram and Dr. Stratman pointed out that another strategy to prevent malpractice is to build trusting patient-provider relationships. “The patient-provider relationship is paramount not only to the success of the procedure but to the clinical visit as a whole,” Dr. Stratman said.
That’s a two-way street, he added. Patients should be able to trust that their provider provides them with the best treatment based on their own history, and providers should also be able to trust that patients are providing them with an accurate history, asking relevant questions, or expressing any level of apprehension about the procedure or visit. “The patient-provider relationship is everything,” Dr. Stratman said.
Dr. Stratman and Dr. Avram had no relevant disclosures.

Cosmetic Botulinum Toxin A Doses May Differ in Sunny Climates
findings from a comparative cohort study suggested.
“Botulinum toxin A to the glabella is a popular cosmetic intervention,” researchers led by Kim L. Borsky, MD, MBBS, of the Department of Plastic and Reconstructive Surgery at Stoke Mandeville Hospital, Aylesbury, England, and colleagues wrote in their study, which was published in Plastic and Reconstructive Surgery. “Functional musculature differences may arise from chronic behavioral adjustment to high sun exposure levels, requiring greater doses. This could affect clinical practice globally.”
To investigate the effect of climate on real-world doses of the product, the researchers enrolled 523 women aged 35-60 years who received glabellar botulinum toxin treatment at two centers between 2012 and 2019: one in the United Kingdom and one in Malta. They evaluated data on 292 patients treated during the summer months at the Malta center (classified as the high sun-exposure group), and 231 patients treated during the winter months at the UK center (classified as the low sun-exposure group). The primary outcomes of interest were the required top-up doses and the total dose to achieve full paralysis. Smokers were excluded from the analysis, as were those who did not seek maximal paralysis, those documented as not compliant with posttreatment advice, and those with colds or fevers. They used univariable and multivariable analyses to compare the high vs low sun-exposure groups.
The researchers found that 68.5% of women in the high-sun group required a top-up dose to achieve full paralysis, compared with 61.5% in the low-sun group, a difference that did not reach statistical significance (P = .1032). All patients achieved full paralysis with the treatment protocol used. However, in the high-sun group, the mean top-up dose was significantly higher than that in the low-sun group (a mean of 9.30 vs 7.06 units, respectively; P = .0009), as was the mean total dose (a mean of 29.23 vs 27.25 units; P = .0031).
“Patients subject to less sun exposure require a lower dose than patients with high sun exposure, and this was present and persisted when controlling for potential confounders,” the researchers wrote. “Although robustly demonstrated, the difference in doses seen here was small, and so may not directly impact at a health economic level, as the difference would not necessarily change the number of vials used. However, it may be of relevance to training and protocolization of treatments. Rigid protocols about doses and distributions may lead to undertreatment if applied in sunnier climates.”

Transgender and Gender Diverse Health Care in the US Military: What Dermatologists Need to Know
People whose gender identity differs from the sex assigned at birth are referred to as transgender. For some, gender identity may not fit into the binary constructs of male and female but rather falls between, within, or outside this construct. These people often consider themselves nonbinary or gender diverse. As the terminology continues to evolve, current recommendations include referring to this patient population as transgender and gender diverse (TGD) to ensure the broadest inclusivity.1 In this article, the following terms are used as defined below:
- The terms transgender woman and trans feminine describe persons who were assigned male gender at birth but their affirmed gender is female or nonmasculine.
- The terms transgender man and trans masculine describe persons who were assigned female gender at birth but their affirmed gender is male or nonfeminine.
The US Military’s policies on the service of TGD persons have evolved considerably over the past decade. Initial military policies barred TGD service members (TSMs) from service all together, leading to challenges in accessing necessary health care. The first official memorandum explicitly allowing military service by TGD persons was released on June 30, 2016.2 The intention of this memorandum was 2-fold: (1) to allow TGD persons to serve in the military so long as they meet “the rigorous standards for military service and readiness” by fulfilling the same standards and procedures as other military service members, including medical fitness for duty, physical fitness, uniform and grooming, deployability, and retention, and (2) to direct the establishment of new or updated policies to specific departments and prescribe procedures for retention standards, separation from service, in-service transition, and medical coverage.2 Several other official policies were released following this initial memorandum that provided more specific guidance on how to implement these policies at the level of the force, unit, and individual service member.
Modifications to the original 2016 policies had varying impacts on transgender health care provision and access.3 At the time of publication of this article, the current policy—the Department of Defense Instruction 1300.284—among others, establishes standards and procedures for the process by which active and reserve TSMs may medically, socially, and legally transition genders within the military. The current policy applies to all military branches and serves as the framework by which each branch currently organizes their gender-affirmation processes (GAP).4
There currently are several different GAP models among the military branches.5 Each branch has a different model or approach to implementing the current policy, with varying service-specific processes in place for TSMs to access gender-affirming care; however, this may be changing. The Defense Health Agency is in the process of consolidating and streamlining the GAP across the Department of Defense branches in an effort to optimize costs and ensure uniformity of care. Per the Defense Health Agency Procedural Instruction Number 6025.21 published in May 2023, the proposed consolidated model likely will entail a single central transgender health center that provides oversight and guidance for several regional joint-service gender-affirming medical hubs. Patients would either be managed at the level of the hub or be referred to the central site.5
Herein, we discuss the importance of gender-affirming care and how military and civilian dermatologists can contribute. We also review disparities in health care and identify areas of improvement.
Benefits of Gender-Affirming Care
Gender-affirming procedures are critical for aligning physical appearance with gender identity. Physical appearance is essential for psychological well-being, operational readiness, and the safety of TSMs.6 It is well documented that TGD persons experience suicidal ideation, depression, stigma, discrimination and violence at higher rates than their cisgender peers.7,8 It is important to recognize that transgender identity is not a mental illness, and these elevated rates have been linked to complex trauma, societal stigma, violence, and discrimination.1 Other studies have suggested that increased access to gender-affirming interventions may ameliorate these mental health concerns.1,7-9
The major components of gender-affirming care include hormone therapy, gender confirmation surgery, and mental health care, if needed. These are covered by TRICARE, the health care program for military service members; however, at the time of publication, many of the dermatologic gender-affirming procedures are not covered by TRICARE because they are considered “cosmetic procedures,” which is a term used by insurance companies but does not accurately indicate whether a procedure is medically necessary or not. Newer literature has demonstrated that gender-affirming care positively affects the lives of TGD patients, strengthening the argument that gender-affirming care is a medical necessity and not just cosmetic.1
Aesthetic Procedures in Gender-Affirming Care
Surgeons, including those within the specialties of oto-laryngology, oral and maxillofacial surgery, urology, gynecology, and plastic surgery, provide major gender-affirming interventions; however, dermatologists may offer less invasive solutions that can serve as a temporary experience prior to undergoing more permanent procedures.Hormonally driven disorders including acne, hair loss, and melasma also are managed by dermatologists, along with scar treatment following surgeries.
Because human variation is expansive and subjective, what is considered feminine or masculine may vary by person, group, culture, and country; therefore, it is imperative to ask patients about their individual aesthetic goals and tailor their treatment accordingly. Feminine and masculine are terms that will be used to describe prototypical appearances and are not meant to define a patient’s current state or ultimate goals. The following procedures and medical interventions are where dermatologists can play an important role in TGD persons’ GAPs.
Botulinum Toxin Injections—Botulinum toxin injection is the most common nonsurgical aesthetic procedure performed around the world.10 The selective paralysis afforded by botulinum toxin has several uses for people undergoing transition. Aesthetically, the feminine eyebrow tends to be positioned above the orbital rim and is arched with its apex between the lateral limbus and lateral canthus,11 while the masculine eyebrow tends to be flatter and fuller and runs over the orbital rim without a peak. For people seeking a more feminine appearance, an eyebrow lift with botulinum toxin can help reshape the typical flatter masculine eyebrow to give it lateral lift that often is considered more feminine. The targeted muscle is the superolateral orbicularis oculi, which serves as a depressor on the eyebrow. This can be combined with purposefully avoiding total lateral frontalis paralysis, which leads to a “Spock” brow for extra lift. Conversely, a naturally arched and higher eyebrow can be flattened and lowered by selectively targeting areas of the frontalis muscle.
Broad square jawlines typically are considered a masculine feature and are another area where botulinum toxin can be used to feminize a patient’s facial features. Targeting the masseter muscle induces muscle weakness, which ultimately may result in atrophy after one or more treatment sessions. This atrophy may lead to narrowing of the lower face and thus may lead to a fuller-appearing midface or overall more heart-shaped face. Every individual’s aesthetic goals are unique and therefore should be discussed prior to any treatment.
Dermal Fillers—Dermal fillers are gel-like substances injected under the skin for subtle contouring of the face. Fillers also can be used to help promote a more masculine or feminine appearance. Filler can be placed in the lips to create a fuller, more projected, feminine-appearing lip. Malar cheek and central lower chin filler can be used to help define a heart-shaped face by accentuating the upper portion of the face and creating a more pointed chin, respectively. Alternatively, filler can be used to masculinize the chin by placing it where it can increase jawline squareness and increase anterior jaw projection. Additionally, filler at the angle of the jaw can help accentuate a square facial shape and a more defined jawline. Although not as widely practiced, lateral brow filler can create a heavier-appearing and broader forehead for a more masculine appearance. These procedures can be combined with the previously mentioned botulinum toxin procedures for a synergistic effect.
Deoxycholic Acid—Deoxycholic acid is an injectable product used to selectively remove unwanted fat. It currently is approved by the US Food and Drug Administration for submental fat, but some providers are experimenting with off-label uses. Buccal fat pad removal—or in this case reduction by dissolution—tends to give a thinner, more feminine facial appearance.12 Reducing fat around the axillae also can help promote a more masculine upper torso.13 The safety of deoxycholic acid in these areas has not been adequately tested; thus, caution should be used when discussing these off-label uses with patients.
Hair and Tattoo Removal—Hair removal may be desired by TGD persons for a variety of reasons. Because cisgender females tend to have less body hair overall, transgender people in pursuit of a more feminine appearance often desire removal of facial, neck, and body hair. Although shaving and other modalities such as waxing and chemical depilatories are readily available at-home options, they are not permanent and may lead to folliculitis or pseudofolliculitis barbae. Laser hair removal (LHR) and electrolysis are modalities provided by dermatologists that tend to be more permanent and lead to better outcomes, including less irritation and better aesthetic appearance. It is important to keep in mind that not every person and not every body site can be safely treated with LHR. Patients with lighter skin types and darker hair tend to have the most effective response with a higher margin of safety, as these features allow the laser energy to be selectively absorbed by the melanin in the hair bulb and not by the background skin pigmentation.14,15 Inappropriate patient selection or improper settings for wavelength, pulse width, or fluences can lead to burns and permanent scarring.14,15 Electrolysis is an alternative to hair removal within tattoos and is more effective for those individuals with blonde, red, or white hair.16
Another novel treatment for unwanted hair is eflornithine hydrochloride cream, which works by blocking ornithine decarboxylase, the enzyme that stimulates hair growth. It currently is approved to reduce unwanted hair on the face and adjacent areas under the chin; however the effects of this medication are modest and the medication can be expensive.17
Cosmetic hair and tattoo removal are not currently covered by TRICARE, except in cases of surgical and donor-site preparation for some GAPs. Individuals may desire removal of tattoos at surgery sites to obtain more natural-appearing skin. Currently, GAPs such as vaginoplasty, phalloplasty, and metoidioplasty—often referred to by patients as “bottom surgeries”—include insurance coverage for tattoo removal, LHR, and/or electrolysis.
Management of Hormonal Adverse Effects
Acne—Individuals on testosterone supplementation tend to develop acne for the first several years of treatment, but it may improve with time.18 Acne is treated in individuals receiving testosterone the same way as it is treated in cisgender men, with numerous options for topical and oral medications. In trans masculine persons, spironolactone therapy typically is avoided because it may interfere with the actions of exogenous testosterone administered as part of gender-affirming medical treatment and may lead to other undesired adverse effects such as impotence and gynecomastia.1
Although acne typically improves after starting estrogen therapy, patients receiving estrogens may still develop acne. Most trans feminine patients will already be on an estrogen and an antiandrogen, often spironolactone.1 Spironolactone often is used as monotherapy for acne control in cisgender women. Additionally, an important factor to consider with spironolactone is the possible adverse effect of increased micturition. Currently, the military rarely has gender-inclusive restroom options, which can create a challenge for TSMs who find themselves needing to use the restroom more frequently in the workplace.
If planning therapy with isotretinoin, dermatologists should discuss several important factors with all patients, including TGD patients. One consideration is the patient’s planned future surgeries. Although new literature shows that isotretinoin does not adversely affect wound healing,19 some surgeons still adhere to an isotretinoin washout period of 6 to 12 months prior to performing any elective procedures due to concerns about wound healing.20,21 Second, be sure to properly assess and document pregnancy potential in TGD persons. Providers should not assume that a patient is not pregnant or is not trying to become pregnant just because they are trans masculine. It also is important to note that testosterone is not a reliable birth control method.1 If a patient still has ovaries, fallopian tubes, and a uterus, they are considered medically capable of pregnancy, and providers should keep this in mind regarding all procedures in the TGD population.
Another newer acne treatment modality is the 1762-nm laser, which targets sebaceous glands.22 This device allows for targeted treatment of acne-prone areas without systemic therapy such as retinoids or antiandrogens. The 1762-nm laser is not widely available but may become a regular treatment option once its benefits are proven over time.
Alopecia and Hyperpigmentation—Androgens, whether endogenously or exogenously derived, can lead to androgenetic alopecia (AGA) in genetically susceptible individuals. Trans masculine persons and others receiving androgen therapy are at higher risk for AGA, which often is undesirable and may be considered gender affirming by some TGD persons. Standard AGA treatments for cisgender men also can be used in trans masculine persons. Some of the most common anti-AGA medications are topical minoxidil, oral finasteride, and oral minoxidil. Although Coleman et al1 recently reported that finasteride may be an appropriate treatment option in trans masculine persons experiencing alopecia, treatment with 5α-reductase inhibitors may impair clitoral growth and the development of facial and body hair. Further studies are needed to assess the efficacy and safety of 5α-reductase inhibitors in transgender populations.1 Dutasteride may be used off-label and comes with a similar potential adverse-event profile as finasteride, which includes depression, decreased libido, erectile dysfunction, ejaculation disorders, and gynecomastia.
Conversely, AGA tends to improve in trans feminine persons and others receiving estrogen and antiandrogen therapy. Natural testosterone production is suppressed by estrogens and spironolactone as well as in patients who undergo orchiectomy.1 Although spironolactone is not approved for acne, AGA, or hirsutism, it is a standard treatment of AGA in cisgender women because it functions to block the effects of androgens, including at the hair follicle. Finasteride may be used for AGA in cisgender women but it is not recommended for trans feminine persons.1
There are many other modalities available for the treatment of AGA that are less commonly used—some may be cost prohibitive or do not have robust supporting evidence, or both. One example is hair
Melasma is a hyperpigmentation disorder related to estrogens, UV light exposure, and sometimes medication use (eg, hormonal birth control, spironolactone).24 The mainstay of treatment is prevention, including sun avoidance as well as use of sun-protective clothing and broad-spectrum sunscreens. Dermatologists tend to recommend physical sunscreens containing zinc oxide, titanium dioxide, and/or iron oxide, as they cover a wider UV spectrum and also provide some protection from visible light. Once melasma is present, dermatologists still have several treatment options. Topical hydroquinone is a proven treatment; however, it must be used with caution to avoid ochronosis. With careful patient selection, chemical peels also are effective treatment options for dyspigmentation and hyperpigmentation. Energy devices such as intense pulsed light and tattoo removal lasers—Q-switched lasers and picosecond pulse widths—also can be used to treat hyperpigmentation. Oral, intralesional, and topical tranexamic acid are newer treatment options for melasma that still are being studied and have shown promising results. Further studies are needed to determine long-term safety and optimal treatment regimens.24,25
Many insurance carriers, including TRICARE, do not routinely cover medical management of AGA or melasma. Patients should be advised that they likely will have to pay for any medications prescribed and procedures undertaken for these purposes; however, some medication costs can be offset by ordering larger prescription quantities, such as a 90-day supply vs a 30-day supply, as well as utilizing pharmacy discount programs.
Scar Management Following Surgery
In TSMs who undergo gender-affirming surgeries, dermatologists play an important role when scar symptoms develop, including pruritus, tenderness, and/or paresthesia. In the military, some common treatment modalities for symptomatic scars include intralesional steroids with or without 5-fluouroruacil and the fractionated CO2 laser. There also are numerous experimental treatment options for scars, including intralesional or perilesional botulinum toxin, the pulsed dye laser, or nonablative fractionated lasers. These modalities also may be used on hypertrophic scars or keloids. Another option for keloids is scar excision followed by superficial radiation therapy.26
Mental Health Considerations
Providers must take psychological adverse effects into consideration when considering medical therapies for dermatologic conditions in TGD patients. In particular, it is important to consider the risks for increased rates of depression and suicidal ideation formerly associated with the use of isotretinoin and finasteride, though much of the evidence regarding these risks has been called into question in recent years.27,28 Nonetheless, it remains prominent in lay media and may be a more important consideration in patients at higher baseline risk.27 Although there are no known studies that have expressly assessed rates of depression or suicidal ideation in TGD patients taking isotretinoin or finasteride, it is well established that TGD persons are at higher baseline risk for depression and suicidality.1,7,8 All patients should be carefully assessed for depression and suicidal ideation as well as counseled regarding these risks prior to initiating these therapies. If concerns for untreated mental health issues arise during screening and counseling, patients should be referred for assessment by a behavioral health specialist prior to starting therapy.
Future Directions
The future of TGD health care in the military could see an expansion of covered benefits and the development of new dermatologic procedures or medications. Research and policy evolution are necessary to bridge the current gaps in care; however, it is unlikely that all procedures currently considered to be cosmetic will become covered benefits.
Facial LHR is a promising candidate for future coverage for trans feminine persons. When cisgender men develop adverse effects from mandatory daily shaving, LHR is already a covered benefit. Two arguments in support of adding LHR for TGD patients revolve around achieving and maintaining an appearance congruent with their gender along with avoiding unwanted adverse effects related to daily shaving. Visual conformity with one’s affirmed gender has been associated with improvements in well-being, quality of life, and some mental health conditions.29
Scar prevention, treatment, and reduction are additional areas under active research in which dermatologists likely will play a crucial role.30,31 As more dermatologic procedures are performed on TGD persons, the published data and collective knowledge regarding best practices in this population will continue to grow, which will lead to improved cosmetic and safety outcomes.
Final Thoughts
Although dermatologists do not directly perform gender-affirming surgeries or hormone management, they do play an important role in enhancing a TGD person’s desired appearance and managing possible adverse effects resulting from gender-affirming interventions. There have been considerable advancements in TGD health care over the past decade, but there likely are more changes on the way. As policies and understanding of TGD health care needs evolve, it is crucial that the military health care system adapts to provide comprehensive, accessible, and equitable care, which includes expanding the range of covered dermatologic treatments to fully support the health and readiness of TSMs.

People whose gender identity differs from the sex assigned at birth are referred to as transgender. For some, gender identity may not fit into the binary constructs of male and female but rather falls between, within, or outside this construct. These people often consider themselves nonbinary or gender diverse. As the terminology continues to evolve, current recommendations include referring to this patient population as transgender and gender diverse (TGD) to ensure the broadest inclusivity.1 In this article, the following terms are used as defined below:
- The terms transgender woman and trans feminine describe persons who were assigned male gender at birth but their affirmed gender is female or nonmasculine.
- The terms transgender man and trans masculine describe persons who were assigned female gender at birth but their affirmed gender is male or nonfeminine.
The US Military’s policies on the service of TGD persons have evolved considerably over the past decade. Initial military policies barred TGD service members (TSMs) from service all together, leading to challenges in accessing necessary health care. The first official memorandum explicitly allowing military service by TGD persons was released on June 30, 2016.2 The intention of this memorandum was 2-fold: (1) to allow TGD persons to serve in the military so long as they meet “the rigorous standards for military service and readiness” by fulfilling the same standards and procedures as other military service members, including medical fitness for duty, physical fitness, uniform and grooming, deployability, and retention, and (2) to direct the establishment of new or updated policies to specific departments and prescribe procedures for retention standards, separation from service, in-service transition, and medical coverage.2 Several other official policies were released following this initial memorandum that provided more specific guidance on how to implement these policies at the level of the force, unit, and individual service member.
Modifications to the original 2016 policies had varying impacts on transgender health care provision and access.3 At the time of publication of this article, the current policy—the Department of Defense Instruction 1300.284—among others, establishes standards and procedures for the process by which active and reserve TSMs may medically, socially, and legally transition genders within the military. The current policy applies to all military branches and serves as the framework by which each branch currently organizes their gender-affirmation processes (GAP).4
There currently are several different GAP models among the military branches.5 Each branch has a different model or approach to implementing the current policy, with varying service-specific processes in place for TSMs to access gender-affirming care; however, this may be changing. The Defense Health Agency is in the process of consolidating and streamlining the GAP across the Department of Defense branches in an effort to optimize costs and ensure uniformity of care. Per the Defense Health Agency Procedural Instruction Number 6025.21 published in May 2023, the proposed consolidated model likely will entail a single central transgender health center that provides oversight and guidance for several regional joint-service gender-affirming medical hubs. Patients would either be managed at the level of the hub or be referred to the central site.5
Herein, we discuss the importance of gender-affirming care and how military and civilian dermatologists can contribute. We also review disparities in health care and identify areas of improvement.
Benefits of Gender-Affirming Care
Gender-affirming procedures are critical for aligning physical appearance with gender identity. Physical appearance is essential for psychological well-being, operational readiness, and the safety of TSMs.6 It is well documented that TGD persons experience suicidal ideation, depression, stigma, discrimination and violence at higher rates than their cisgender peers.7,8 It is important to recognize that transgender identity is not a mental illness, and these elevated rates have been linked to complex trauma, societal stigma, violence, and discrimination.1 Other studies have suggested that increased access to gender-affirming interventions may ameliorate these mental health concerns.1,7-9
The major components of gender-affirming care include hormone therapy, gender confirmation surgery, and mental health care, if needed. These are covered by TRICARE, the health care program for military service members; however, at the time of publication, many of the dermatologic gender-affirming procedures are not covered by TRICARE because they are considered “cosmetic procedures,” which is a term used by insurance companies but does not accurately indicate whether a procedure is medically necessary or not. Newer literature has demonstrated that gender-affirming care positively affects the lives of TGD patients, strengthening the argument that gender-affirming care is a medical necessity and not just cosmetic.1
Aesthetic Procedures in Gender-Affirming Care
Surgeons, including those within the specialties of oto-laryngology, oral and maxillofacial surgery, urology, gynecology, and plastic surgery, provide major gender-affirming interventions; however, dermatologists may offer less invasive solutions that can serve as a temporary experience prior to undergoing more permanent procedures.Hormonally driven disorders including acne, hair loss, and melasma also are managed by dermatologists, along with scar treatment following surgeries.
Because human variation is expansive and subjective, what is considered feminine or masculine may vary by person, group, culture, and country; therefore, it is imperative to ask patients about their individual aesthetic goals and tailor their treatment accordingly. Feminine and masculine are terms that will be used to describe prototypical appearances and are not meant to define a patient’s current state or ultimate goals. The following procedures and medical interventions are where dermatologists can play an important role in TGD persons’ GAPs.
Botulinum Toxin Injections—Botulinum toxin injection is the most common nonsurgical aesthetic procedure performed around the world.10 The selective paralysis afforded by botulinum toxin has several uses for people undergoing transition. Aesthetically, the feminine eyebrow tends to be positioned above the orbital rim and is arched with its apex between the lateral limbus and lateral canthus,11 while the masculine eyebrow tends to be flatter and fuller and runs over the orbital rim without a peak. For people seeking a more feminine appearance, an eyebrow lift with botulinum toxin can help reshape the typical flatter masculine eyebrow to give it lateral lift that often is considered more feminine. The targeted muscle is the superolateral orbicularis oculi, which serves as a depressor on the eyebrow. This can be combined with purposefully avoiding total lateral frontalis paralysis, which leads to a “Spock” brow for extra lift. Conversely, a naturally arched and higher eyebrow can be flattened and lowered by selectively targeting areas of the frontalis muscle.
Broad square jawlines typically are considered a masculine feature and are another area where botulinum toxin can be used to feminize a patient’s facial features. Targeting the masseter muscle induces muscle weakness, which ultimately may result in atrophy after one or more treatment sessions. This atrophy may lead to narrowing of the lower face and thus may lead to a fuller-appearing midface or overall more heart-shaped face. Every individual’s aesthetic goals are unique and therefore should be discussed prior to any treatment.
Dermal Fillers—Dermal fillers are gel-like substances injected under the skin for subtle contouring of the face. Fillers also can be used to help promote a more masculine or feminine appearance. Filler can be placed in the lips to create a fuller, more projected, feminine-appearing lip. Malar cheek and central lower chin filler can be used to help define a heart-shaped face by accentuating the upper portion of the face and creating a more pointed chin, respectively. Alternatively, filler can be used to masculinize the chin by placing it where it can increase jawline squareness and increase anterior jaw projection. Additionally, filler at the angle of the jaw can help accentuate a square facial shape and a more defined jawline. Although not as widely practiced, lateral brow filler can create a heavier-appearing and broader forehead for a more masculine appearance. These procedures can be combined with the previously mentioned botulinum toxin procedures for a synergistic effect.
Deoxycholic Acid—Deoxycholic acid is an injectable product used to selectively remove unwanted fat. It currently is approved by the US Food and Drug Administration for submental fat, but some providers are experimenting with off-label uses. Buccal fat pad removal—or in this case reduction by dissolution—tends to give a thinner, more feminine facial appearance.12 Reducing fat around the axillae also can help promote a more masculine upper torso.13 The safety of deoxycholic acid in these areas has not been adequately tested; thus, caution should be used when discussing these off-label uses with patients.
Hair and Tattoo Removal—Hair removal may be desired by TGD persons for a variety of reasons. Because cisgender females tend to have less body hair overall, transgender people in pursuit of a more feminine appearance often desire removal of facial, neck, and body hair. Although shaving and other modalities such as waxing and chemical depilatories are readily available at-home options, they are not permanent and may lead to folliculitis or pseudofolliculitis barbae. Laser hair removal (LHR) and electrolysis are modalities provided by dermatologists that tend to be more permanent and lead to better outcomes, including less irritation and better aesthetic appearance. It is important to keep in mind that not every person and not every body site can be safely treated with LHR. Patients with lighter skin types and darker hair tend to have the most effective response with a higher margin of safety, as these features allow the laser energy to be selectively absorbed by the melanin in the hair bulb and not by the background skin pigmentation.14,15 Inappropriate patient selection or improper settings for wavelength, pulse width, or fluences can lead to burns and permanent scarring.14,15 Electrolysis is an alternative to hair removal within tattoos and is more effective for those individuals with blonde, red, or white hair.16
Another novel treatment for unwanted hair is eflornithine hydrochloride cream, which works by blocking ornithine decarboxylase, the enzyme that stimulates hair growth. It currently is approved to reduce unwanted hair on the face and adjacent areas under the chin; however the effects of this medication are modest and the medication can be expensive.17
Cosmetic hair and tattoo removal are not currently covered by TRICARE, except in cases of surgical and donor-site preparation for some GAPs. Individuals may desire removal of tattoos at surgery sites to obtain more natural-appearing skin. Currently, GAPs such as vaginoplasty, phalloplasty, and metoidioplasty—often referred to by patients as “bottom surgeries”—include insurance coverage for tattoo removal, LHR, and/or electrolysis.
Management of Hormonal Adverse Effects
Acne—Individuals on testosterone supplementation tend to develop acne for the first several years of treatment, but it may improve with time.18 Acne is treated in individuals receiving testosterone the same way as it is treated in cisgender men, with numerous options for topical and oral medications. In trans masculine persons, spironolactone therapy typically is avoided because it may interfere with the actions of exogenous testosterone administered as part of gender-affirming medical treatment and may lead to other undesired adverse effects such as impotence and gynecomastia.1
Although acne typically improves after starting estrogen therapy, patients receiving estrogens may still develop acne. Most trans feminine patients will already be on an estrogen and an antiandrogen, often spironolactone.1 Spironolactone often is used as monotherapy for acne control in cisgender women. Additionally, an important factor to consider with spironolactone is the possible adverse effect of increased micturition. Currently, the military rarely has gender-inclusive restroom options, which can create a challenge for TSMs who find themselves needing to use the restroom more frequently in the workplace.
If planning therapy with isotretinoin, dermatologists should discuss several important factors with all patients, including TGD patients. One consideration is the patient’s planned future surgeries. Although new literature shows that isotretinoin does not adversely affect wound healing,19 some surgeons still adhere to an isotretinoin washout period of 6 to 12 months prior to performing any elective procedures due to concerns about wound healing.20,21 Second, be sure to properly assess and document pregnancy potential in TGD persons. Providers should not assume that a patient is not pregnant or is not trying to become pregnant just because they are trans masculine. It also is important to note that testosterone is not a reliable birth control method.1 If a patient still has ovaries, fallopian tubes, and a uterus, they are considered medically capable of pregnancy, and providers should keep this in mind regarding all procedures in the TGD population.
Another newer acne treatment modality is the 1762-nm laser, which targets sebaceous glands.22 This device allows for targeted treatment of acne-prone areas without systemic therapy such as retinoids or antiandrogens. The 1762-nm laser is not widely available but may become a regular treatment option once its benefits are proven over time.
Alopecia and Hyperpigmentation—Androgens, whether endogenously or exogenously derived, can lead to androgenetic alopecia (AGA) in genetically susceptible individuals. Trans masculine persons and others receiving androgen therapy are at higher risk for AGA, which often is undesirable and may be considered gender affirming by some TGD persons. Standard AGA treatments for cisgender men also can be used in trans masculine persons. Some of the most common anti-AGA medications are topical minoxidil, oral finasteride, and oral minoxidil. Although Coleman et al1 recently reported that finasteride may be an appropriate treatment option in trans masculine persons experiencing alopecia, treatment with 5α-reductase inhibitors may impair clitoral growth and the development of facial and body hair. Further studies are needed to assess the efficacy and safety of 5α-reductase inhibitors in transgender populations.1 Dutasteride may be used off-label and comes with a similar potential adverse-event profile as finasteride, which includes depression, decreased libido, erectile dysfunction, ejaculation disorders, and gynecomastia.
Conversely, AGA tends to improve in trans feminine persons and others receiving estrogen and antiandrogen therapy. Natural testosterone production is suppressed by estrogens and spironolactone as well as in patients who undergo orchiectomy.1 Although spironolactone is not approved for acne, AGA, or hirsutism, it is a standard treatment of AGA in cisgender women because it functions to block the effects of androgens, including at the hair follicle. Finasteride may be used for AGA in cisgender women but it is not recommended for trans feminine persons.1
There are many other modalities available for the treatment of AGA that are less commonly used—some may be cost prohibitive or do not have robust supporting evidence, or both. One example is hair
Melasma is a hyperpigmentation disorder related to estrogens, UV light exposure, and sometimes medication use (eg, hormonal birth control, spironolactone).24 The mainstay of treatment is prevention, including sun avoidance as well as use of sun-protective clothing and broad-spectrum sunscreens. Dermatologists tend to recommend physical sunscreens containing zinc oxide, titanium dioxide, and/or iron oxide, as they cover a wider UV spectrum and also provide some protection from visible light. Once melasma is present, dermatologists still have several treatment options. Topical hydroquinone is a proven treatment; however, it must be used with caution to avoid ochronosis. With careful patient selection, chemical peels also are effective treatment options for dyspigmentation and hyperpigmentation. Energy devices such as intense pulsed light and tattoo removal lasers—Q-switched lasers and picosecond pulse widths—also can be used to treat hyperpigmentation. Oral, intralesional, and topical tranexamic acid are newer treatment options for melasma that still are being studied and have shown promising results. Further studies are needed to determine long-term safety and optimal treatment regimens.24,25
Many insurance carriers, including TRICARE, do not routinely cover medical management of AGA or melasma. Patients should be advised that they likely will have to pay for any medications prescribed and procedures undertaken for these purposes; however, some medication costs can be offset by ordering larger prescription quantities, such as a 90-day supply vs a 30-day supply, as well as utilizing pharmacy discount programs.
Scar Management Following Surgery
In TSMs who undergo gender-affirming surgeries, dermatologists play an important role when scar symptoms develop, including pruritus, tenderness, and/or paresthesia. In the military, some common treatment modalities for symptomatic scars include intralesional steroids with or without 5-fluouroruacil and the fractionated CO2 laser. There also are numerous experimental treatment options for scars, including intralesional or perilesional botulinum toxin, the pulsed dye laser, or nonablative fractionated lasers. These modalities also may be used on hypertrophic scars or keloids. Another option for keloids is scar excision followed by superficial radiation therapy.26
Mental Health Considerations
Providers must take psychological adverse effects into consideration when considering medical therapies for dermatologic conditions in TGD patients. In particular, it is important to consider the risks for increased rates of depression and suicidal ideation formerly associated with the use of isotretinoin and finasteride, though much of the evidence regarding these risks has been called into question in recent years.27,28 Nonetheless, it remains prominent in lay media and may be a more important consideration in patients at higher baseline risk.27 Although there are no known studies that have expressly assessed rates of depression or suicidal ideation in TGD patients taking isotretinoin or finasteride, it is well established that TGD persons are at higher baseline risk for depression and suicidality.1,7,8 All patients should be carefully assessed for depression and suicidal ideation as well as counseled regarding these risks prior to initiating these therapies. If concerns for untreated mental health issues arise during screening and counseling, patients should be referred for assessment by a behavioral health specialist prior to starting therapy.
Future Directions
The future of TGD health care in the military could see an expansion of covered benefits and the development of new dermatologic procedures or medications. Research and policy evolution are necessary to bridge the current gaps in care; however, it is unlikely that all procedures currently considered to be cosmetic will become covered benefits.
Facial LHR is a promising candidate for future coverage for trans feminine persons. When cisgender men develop adverse effects from mandatory daily shaving, LHR is already a covered benefit. Two arguments in support of adding LHR for TGD patients revolve around achieving and maintaining an appearance congruent with their gender along with avoiding unwanted adverse effects related to daily shaving. Visual conformity with one’s affirmed gender has been associated with improvements in well-being, quality of life, and some mental health conditions.29
Scar prevention, treatment, and reduction are additional areas under active research in which dermatologists likely will play a crucial role.30,31 As more dermatologic procedures are performed on TGD persons, the published data and collective knowledge regarding best practices in this population will continue to grow, which will lead to improved cosmetic and safety outcomes.
Final Thoughts
Although dermatologists do not directly perform gender-affirming surgeries or hormone management, they do play an important role in enhancing a TGD person’s desired appearance and managing possible adverse effects resulting from gender-affirming interventions. There have been considerable advancements in TGD health care over the past decade, but there likely are more changes on the way. As policies and understanding of TGD health care needs evolve, it is crucial that the military health care system adapts to provide comprehensive, accessible, and equitable care, which includes expanding the range of covered dermatologic treatments to fully support the health and readiness of TSMs.

It also is important to note that testosterone is not a reliable birth control method.1 If a patient still has ovaries, fallopian tubes, and a uterus, they are considered medically capable of pregnancy, and providers should keep this in mind regarding all procedures in the TGD population.
Another newer acne treatment modality is the 1762-nm laser, which targets sebaceous glands.22 This device allows for targeted treatment of acne-prone areas without systemic therapy such as retinoids or antiandrogens. The 1762-nm laser is not widely available but may become a regular treatment option once its benefits are proven over time.
Alopecia and Hyperpigmentation—Androgens, whether endogenously or exogenously derived, can lead to androgenetic alopecia (AGA) in genetically susceptible individuals. Trans masculine persons and others receiving androgen therapy are at higher risk for AGA, which often is undesirable and may be considered gender affirming by some TGD persons. Standard AGA treatments for cisgender men also can be used in trans masculine persons. Some of the most common anti-AGA medications are topical minoxidil, oral finasteride, and oral minoxidil. Although Coleman et al1 recently reported that finasteride may be an appropriate treatment option in trans masculine persons experiencing alopecia, treatment with 5α-reductase inhibitors may impair clitoral growth and the development of facial and body hair. Further studies are needed to assess the efficacy and safety of 5α-reductase inhibitors in transgender populations.1 Dutasteride may be used off-label and comes with a similar potential adverse-event profile as finasteride, which includes depression, decreased libido, erectile dysfunction, ejaculation disorders, and gynecomastia.
Conversely, AGA tends to improve in trans feminine persons and others receiving estrogen and antiandrogen therapy. Natural testosterone production is suppressed by estrogens and spironolactone as well as in patients who undergo orchiectomy.1 Although spironolactone is not approved for acne, AGA, or hirsutism, it is a standard treatment of AGA in cisgender women because it functions to block the effects of androgens, including at the hair follicle. Finasteride may be used for AGA in cisgender women but it is not recommended for trans feminine persons.1
There are many other modalities available for the treatment of AGA that are less commonly used—some may be cost prohibitive or do not have robust supporting evidence, or both. One example is hair
Melasma is a hyperpigmentation disorder related to estrogens, UV light exposure, and sometimes medication use (eg, hormonal birth control, spironolactone).24 The mainstay of treatment is prevention, including sun avoidance as well as use of sun-protective clothing and broad-spectrum sunscreens. Dermatologists tend to recommend physical sunscreens containing zinc oxide, titanium dioxide, and/or iron oxide, as they cover a wider UV spectrum and also provide some protection from visible light. Once melasma is present, dermatologists still have several treatment options. Topical hydroquinone is a proven treatment; however, it must be used with caution to avoid ochronosis. With careful patient selection, chemical peels also are effective treatment options for dyspigmentation and hyperpigmentation. Energy devices such as intense pulsed light and tattoo removal lasers—Q-switched lasers and picosecond pulse widths—also can be used to treat hyperpigmentation. Oral, intralesional, and topical tranexamic acid are newer treatment options for melasma that still are being studied and have shown promising results. Further studies are needed to determine long-term safety and optimal treatment regimens.24,25
Many insurance carriers, including TRICARE, do not routinely cover medical management of AGA or melasma. Patients should be advised that they likely will have to pay for any medications prescribed and procedures undertaken for these purposes; however, some medication costs can be offset by ordering larger prescription quantities, such as a 90-day supply vs a 30-day supply, as well as utilizing pharmacy discount programs.
Scar Management Following Surgery
In TSMs who undergo gender-affirming surgeries, dermatologists play an important role when scar symptoms develop, including pruritus, tenderness, and/or paresthesia. In the military, some common treatment modalities for symptomatic scars include intralesional steroids with or without 5-fluouroruacil and the fractionated CO2 laser. There also are numerous experimental treatment options for scars, including intralesional or perilesional botulinum toxin, the pulsed dye laser, or nonablative fractionated lasers. These modalities also may be used on hypertrophic scars or keloids. Another option for keloids is scar excision followed by superficial radiation therapy.26
Mental Health Considerations
Providers must take psychological adverse effects into consideration when considering medical therapies for dermatologic conditions in TGD patients. In particular, it is important to consider the risks for increased rates of depression and suicidal ideation formerly associated with the use of isotretinoin and finasteride, though much of the evidence regarding these risks has been called into question in recent years.27,28 Nonetheless, it remains prominent in lay media and may be a more important consideration in patients at higher baseline risk.27 Although there are no known studies that have expressly assessed rates of depression or suicidal ideation in TGD patients taking isotretinoin or finasteride, it is well established that TGD persons are at higher baseline risk for depression and suicidality.1,7,8 All patients should be carefully assessed for depression and suicidal ideation as well as counseled regarding these risks prior to initiating these therapies. If concerns for untreated mental health issues arise during screening and counseling, patients should be referred for assessment by a behavioral health specialist prior to starting therapy.
Future Directions
The future of TGD health care in the military could see an expansion of covered benefits and the development of new dermatologic procedures or medications. Research and policy evolution are necessary to bridge the current gaps in care; however, it is unlikely that all procedures currently considered to be cosmetic will become covered benefits.
Facial LHR is a promising candidate for future coverage for trans feminine persons. When cisgender men develop adverse effects from mandatory daily shaving, LHR is already a covered benefit. Two arguments in support of adding LHR for TGD patients revolve around achieving and maintaining an appearance congruent with their gender along with avoiding unwanted adverse effects related to daily shaving. Visual conformity with one’s affirmed gender has been associated with improvements in well-being, quality of life, and some mental health conditions.29
Scar prevention, treatment, and reduction are additional areas under active research in which dermatologists likely will play a crucial role.30,31 As more dermatologic procedures are performed on TGD persons, the published data and collective knowledge regarding best practices in this population will continue to grow, which will lead to improved cosmetic and safety outcomes.
Final Thoughts
Although dermatologists do not directly perform gender-affirming surgeries or hormone management, they do play an important role in enhancing a TGD person’s desired appearance and managing possible adverse effects resulting from gender-affirming interventions. There have been considerable advancements in TGD health care over the past decade, but there likely are more changes on the way. As policies and understanding of TGD health care needs evolve, it is crucial that the military health care system adapts to provide comprehensive, accessible, and equitable care, which includes expanding the range of covered dermatologic treatments to fully support the health and readiness of TSMs.

Practice Points
- Transgender and gender diverse (TGD) health care is multidisciplinary, and both military and civilian dermatologists can serve an important role.
- Although dermatologists do not directly perform gender-affirming surgeries or hormone management, there are a number of dermatologic procedures and medical interventions that can enhance a TGD person’s desired appearance.
- Dermatologists also can help manage possible adverse effects from gender-affirming interventions.
Study Addresses Litigation Related to Cutaneous Energy-based Based Device Treatments
“The utilization of laser and energy-based devices (LEBD) has grown substantially,” corresponding author Scott Stratman, MD, MPH, and coauthors wrote in their study, which was published online in the Journal of the American Academy of Dermatology. “This has led to a rise in practitioners, both physicians and nonphysicians, who may lack the requisite training in LEBD procedures. Subsequently, procedures performed by these untrained practitioners have resulted in more lawsuits related to patient complications. As the demand for LEBD procedures and the number of practitioners performing these procedures increase, it remains paramount to characterize the trends of malpractice cases involving these procedures.”
Dr. Stratman, a dermatology resident at the Icahn School of Medicine at Mount Sinai, New York City, and colleagues queried the LexisNexis database from 1985 to Sept. 30, 2023, for all state, federal, and appellate cases that included the terms “negligence” or “malpractice” and “skin” and “laser.” After they removed duplicate cases and excluded cases that did not report dermatologic complications or cutaneous energy-based procedures, the final analysis included 75 cases.
Most of the appellants/plaintiffs (66; 88%) were women, a greater number of cases were in the Northeast (26; 34.7%) and the South (23; 30.7%), and the fewest cases were in the Midwest (12 [16%]). The most common anatomical sites were the face, head, and/or neck, and 43 of the cases (57.3%) were decided in favor of the appellee/defendant or the party defending against the appeal, while 29 (38.7%) were in favor of the appellant/plaintiff or the party appealing, and three cases (4%) did not report a verdict.
In other findings, plastic surgeons were the most litigated healthcare professionals (18; 24%), while 39 of the overall cases (52%) involved nonphysician operators (NPOs), 32 (42.7%) involved a physician operator, and 4 cases (5.3%) did not name a device operator. The most common procedure performed in the included cases was laser hair removal (33; 44%). Complications from energy-based devices included burns, scarring, and pigmentation changes. Statistically significant associations were neither found between verdict outcome and appellee/defendant type nor found between energy-device operator or anatomical site.
The authors acknowledged certain limitations of the study, including the fact that the LexisNexis database does not contain cases handled in out-of-court settlements and cases that underwent third-party arbitration.
“Physicians must recognize their responsibility when delegating procedures to NPOs and their role in supervision of these procedures,” they concluded. “Comprehensive training for physicians and their agents is necessary to diminish adverse outcomes and legal risks. Moreover, all practitioners should be held to the same standard of care. Familiarity with malpractice trends not only strengthens the patient-provider relationship but also equips providers with effective strategies to minimize the risk of legal repercussions.”
Mathew M. Avram, MD, JD, director of laser, cosmetics, and dermatologic surgery at Massachusetts General Hospital, Boston, who was asked to comment on the study, said that it “reaffirms previous studies which show that laser hair removal continues to be the most litigated procedure in laser surgery, and that nonphysician operators are most commonly litigated against. It further reiterates the importance of close supervision and expert training of procedures delegated by physicians.”
Neither the authors nor Dr. Avram reported having relevant financial disclosures.

Familiarity with malpractice trends not only strengthens the patient-provider relationship but also equips providers with effective strategies to minimize the risk of legal repercussions.”
Mathew M. Avram, MD, JD, director of laser, cosmetics, and dermatologic surgery at Massachusetts General Hospital, Boston, who was asked to comment on the study, said that it “reaffirms previous studies which show that laser hair removal continues to be the most litigated procedure in laser surgery, and that nonphysician operators are most commonly litigated against. It further reiterates the importance of close supervision and expert training of procedures delegated by physicians.”

“The utilization of laser and energy-based devices (LEBD) has grown substantially,” corresponding author Scott Stratman, MD, MPH, and coauthors wrote in their study, which was published online in the Journal of the American Academy of Dermatology. “This has led to a rise in practitioners, both physicians and nonphysicians, who may lack the requisite training in LEBD procedures. Subsequently, procedures performed by these untrained practitioners have resulted in more lawsuits related to patient complications. As the demand for LEBD procedures and the number of practitioners performing these procedures increase, it remains paramount to characterize the trends of malpractice cases involving these procedures.”
Dr. Stratman, a dermatology resident at the Icahn School of Medicine at Mount Sinai, New York City, and colleagues queried the LexisNexis database from 1985 to Sept. 30, 2023, for all state, federal, and appellate cases that included the terms “negligence” or “malpractice” and “skin” and “laser.” After they removed duplicate cases and excluded cases that did not report dermatologic complications or cutaneous energy-based procedures, the final analysis included 75 cases.
Most of the appellants/plaintiffs (66; 88%) were women, a greater number of cases were in the Northeast (26; 34.7%) and the South (23; 30.7%), and the fewest cases were in the Midwest (12 [16%]). The most common anatomical sites were the face, head, and/or neck, and 43 of the cases (57.3%) were decided in favor of the appellee/defendant or the party defending against the appeal, while 29 (38.7%) were in favor of the appellant/plaintiff or the party appealing, and three cases (4%) did not report a verdict.
In other findings, plastic surgeons were the most litigated healthcare professionals (18; 24%), while 39 of the overall cases (52%) involved nonphysician operators (NPOs), 32 (42.7%) involved a physician operator, and 4 cases (5.3%) did not name a device operator. The most common procedure performed in the included cases was laser hair removal (33; 44%). Complications from energy-based devices included burns, scarring, and pigmentation changes. Statistically significant associations were neither found between verdict outcome and appellee/defendant type nor found between energy-device operator or anatomical site.
The authors acknowledged certain limitations of the study, including the fact that the LexisNexis database does not contain cases handled in out-of-court settlements and cases that underwent third-party arbitration.

Meta-Analysis Finds Combination Cream Plus Tranexamic Acid Effective for Melasma
TOPLINE:
A meta-analysis showed that .
METHODOLOGY:
- Current treatments for melasma focus on inducing remission and preventing relapse. Tranexamic acid, an antifibrinolytic drug, has shown promise in recent studies, but its optimal use, either alone or as an adjunct to TCC, remains unclear.
- Researchers conducted a meta-analysis of four randomized controlled trials patients that compared oral tranexamic acid plus TCC (hydroquinone, retinoic acid, and hydrocortisone) and TCC alone in 480 patients with melasma, divided almost evenly into the two treatment groups.
- The main outcome was the change in the Melasma Severity Area Index (MASI) score and recurrence rate from baseline.
TAKEAWAY:
- Patients treated with oral tranexamic acid plus TCC showed a greater reduction in MASI scores compared with those who received TCC alone (mean difference, −3.10; P = .03).
- The recurrence rate of melasma was significantly lower in the tranexamic acid plus TCC group (risk ratio [RR], 0.28; P < .001).
- There was no significant difference in the incidences of erythema (RR, 0.63; P = .147) and burning (RR, 0.59; P = .131).
IN PRACTICE:
“Evidence indicates that oral tranexamic acid confers clinical benefits, contributing to the enhancement of treatment outcomes in melasma when used in conjunction with TCC therapy,” and results are promising with regards to minimizing recurrence, the authors concluded.
SOURCE:
The study was led by Ocílio Ribeiro Gonçalves, MS, of the Federal University of Piauí, Teresina, Brazil, and was published online on June 8, 2024, in Clinical and Experimental Dermatology.
LIMITATIONS:
There was heterogeneity across studies, including different methods of administration, treatment protocols (including dosage), and timing of treatment.
DISCLOSURES:
The study reported receiving no funding. The authors declared no conflicts of interest.

Macadamia and Sapucaia Extracts and the Skin
Macadamia (Macadamia tetraphylla) is endemic to Australia and is now commercially cultivated worldwide.1 It is closely related genetically to the other macadamia plants, including the other main one, M. integrifolia, cultivated for macadamia nuts. Known in Brazil as sapucaia or castanha-de-sapucaia, Lecythis pisonis (also referred to as “cream nut” or “monkey pot”) is a large, deciduous tropical tree and member of the Brazil nut family, Lecythidaceae.2 Various parts of both of these plants have been associated with medicinal properties, including the potential for dermatologic activity. Notably, the leaves of L. pisonis have been used in traditional medicine to treat pruritus.2.
Macadamia
Extraction to Harness Antioxidant Activity
In 2015, Dailey and Vuong developed an aqueous extraction process to recover the phenolic content and antioxidant functionality from the skin waste of M. tetraphylla using response surface methodology. As an environmentally suitable solvent that is also cheap and safe, water was chosen to maximize the extraction scenario. They identified the proper conditions (90° C, a time of 20 min, and a sample-to-solvent ratio of 5 g/100 mL) to obtain sufficient phenolic compounds, proanthocyanidins, and flavonoids to render robust antioxidant function.1
Early in 2023, Somwongin et al. investigated various green extraction methods for viability in harnessing the cosmetic/cosmeceutical ingredients of M. integrifolia pericarps. Extracts were assessed for total phenolic content as well as antioxidant and anti–skin aging functions. They found that among the green extraction methods (ultrasound, micellar, microwave, and pulsed electric field extraction with water used as a clean solvent), the ultrasound-assisted extraction method netted the greatest yield and total phenolic content. It was also associated with the most robust antioxidant and anti–skin aging activities. Indeed, the researchers reported that its antioxidant activities were comparable to ascorbic acid and Trolox and its anti–skin aging potency on a par with epigallocatechin-3-gallate and oleanolic acid. The ultrasound-assisted extract was also deemed safe as it did not provoke irritation. The authors concluded that this environmentally suitable extraction method for M. integrifolia is appropriate for obtaining effective macadamia extracts for use in cosmetics and cosmeceuticals.3
Anti-Aging Activity
In 2017, Addy et al. set out to characterize skin surface lipid composition and differences in an age- and sex-controlled population as a foundation for developing a botanically derived skin surface lipid mimetic agent. They noted that fatty acids, triglycerides, cholesterol, steryl esters, wax esters, and squalene are the main constituents of skin surface lipids. The investigators obtained skin surface lipid samples from the foreheads of 59 healthy 22-year-old women, analyzed them, and used the raw components of M. integrifolia, Simmondsia chinensis, and Olea europaea to engineer a mimetic product. They reported that the esterification reactions of jojoba, macadamia, and tall oils, combined with squalene derived from O. europaea, yielded an appropriate skin surface lipid mimetic, which, when applied to delipidized skin, assisted in recovering barrier function, enhancing skin hydration, and improving elasticity as well as firmness in aged skin. The researchers concluded that this skin surface lipid mimetic could serve as an effective supplement to human skin surface lipids in aged skin and for conditions in which the stratum corneum is impaired.4
Two years later, Hanum et al. compared the effects of macadamia nut oil nanocream and conventional cream for treating cutaneous aging over a 4-week period. The macadamia nut oil nanocream, which contained macadamia nut oil 10%, tween 80, propylene glycol, cetyl alcohol, methylparaben, propylparaben, and distilled water, was compared with the conventional cream based on effects on moisture, evenness, pore size, melanin, and wrinkling. The macadamia nut oil was found to yield superior anti-aging activity along each parameter as compared with the conventional cream. The researchers concluded that the macadamia nut oil in nanocream can be an effective formulation for providing benefits in addressing cutaneous aging.5
Macadamia nut oil has also been used in an anti-aging emulsion that was evaluated in a small study with 11 volunteers in 2008. Akhtar et al. prepared multiple emulsions of vitamin C and wheat protein using macadamia oil for its abundant supply of palmitoleic acid. Over 4 weeks, the emulsion was found to increase skin moisture without affecting other skin parameters, such as elasticity, erythema, melanin, pH, or sebum levels.6
Sapucaia (L. pisonis), an ornamental tree that is used for timber, produces edible, nutritious nuts that are rich in tocopherols, polyphenols, and fatty acids.7,8 In 2018, Demoliner et al. identified and characterized the phenolic substances present in sapucaia nut extract and its shell. Antioxidant activity conferred by the extract was attributed to the copious supply of catechin, epicatechin, and myricetin, as well as ellagic and ferulic acids, among the 14 phenolic constituents. The shell included 22 phenolic substances along with a significant level of condensed tannins and marked antioxidant function. The authors correlated the substantial activity imparted by the shell with its higher phenolic content, and suggested this robust source of natural antioxidants could be well suited to use in cosmetic products.9
Antifungal Activity
In 2015, Vieira et al. characterized 12 fractions enriched in peptides derived from L. pisonis seeds to determine inhibitory activity against Candida albicans. The fraction that exerted the strongest activity at 10 μg/mL, suppressing C. albicans growth by 38.5% and inducing a 69.3% loss of viability, was identified as similar to plant defensins and thus dubbed “L. pisonis defensin 1 (Lp-Def1).” The investigators concluded that Lp-Def1 acts on C. albicans by slightly elevating the induction of reactive oxygen species and causing a significant reduction in mitochondrial activity. They suggested that their findings support the use of plant defensins, particularly Lp-Def1, in the formulation of antifungal products, especially to address C. albicans.10
Pruritus
In 2012, Silva et al. studied the antipruritic impact of L. pisonis leaf extracts in mice and rats. Pretreatment with the various fractions of L. pisonis as well as constituent mixed triterpenes (ursolic and oleanolic acids) significantly blocked scratching behavior provoked by compound 48/80. The degranulation of rat peritoneal mast cells caused by compound 48/80 was also substantially decreased from pretreatment with the ethanol extract of L. pisonis, ether-L. pisonis fraction, and mixed triterpenes. The L. pisonis ether fraction suppressed edema induced by carrageenan administration and the ethanol extract displayed no toxicity up to an oral dose of 2g/kg. The investigators concluded that their results strongly support the antipruritic effects of L. pisonis leaves as well as the traditional use of the plant to treat pruritus.2
Stability for Cosmetic Creams
In 2020, Rampazzo et al. assessed the stability and cytotoxicity of a cosmetic cream containing sapucaia nut oil. All three tested concentrations (1%, 5%, and 10%) of the cream were found to be stable, with an effective preservative system, and deemed safe for use on human skin. To maintain a pH appropriate for a body cream, the formulation requires a stabilizing agent. The cream with 5% nut oil was identified as the most stable and satisfying for use on the skin.7
More recently, Hertel Pereira et al. investigated the benefits of using L. pisonis pericarp extract, known to exhibit abundant antioxidants, in an all-natural skin cream. They found that formulation instability increased proportionally with the concentration of the extract, but the use of the outer pericarp of L. pisonis was well suited for the cream formulation, with physical-chemical and organoleptic qualities unchanged after the stability test.11
Conclusion
The available literature on the medical applications of macadamia and sapucaia plants is sparse. Some recent findings are promising regarding possible uses in skin health. However, much more research is necessary before considering macadamia and sapucaia as viable sources of botanical agents capable of delivering significant cutaneous benefits.

The macadamia nut oil nanocream, which contained macadamia nut oil 10%, tween 80, propylene glycol, cetyl alcohol, methylparaben, propylparaben, and distilled water, was compared with the conventional cream based on effects on moisture, evenness, pore size, melanin, and wrinkling. The macadamia nut oil was found to yield superior anti-aging activity along each parameter as compared with the conventional cream. The researchers concluded that the macadamia nut oil in nanocream can be an effective formulation for providing benefits in addressing cutaneous aging.5
Macadamia nut oil has also been used in an anti-aging emulsion that was evaluated in a small study with 11 volunteers in 2008. Akhtar et al. prepared multiple emulsions of vitamin C and wheat protein using macadamia oil for its abundant supply of palmitoleic acid. Over 4 weeks, the emulsion was found to increase skin moisture without affecting other skin parameters, such as elasticity, erythema, melanin, pH, or sebum levels.6
Sapucaia (L. pisonis), an ornamental tree that is used for timber, produces edible, nutritious nuts that are rich in tocopherols, polyphenols, and fatty acids.7,8 In 2018, Demoliner et al. identified and characterized the phenolic substances present in sapucaia nut extract and its shell. Antioxidant activity conferred by the extract was attributed to the copious supply of catechin, epicatechin, and myricetin, as well as ellagic and ferulic acids, among the 14 phenolic constituents. The shell included 22 phenolic substances along with a significant level of condensed tannins and marked antioxidant function. The authors correlated the substantial activity imparted by the shell with its higher phenolic content, and suggested this robust source of natural antioxidants could be well suited to use in cosmetic products.9
Antifungal Activity
In 2015, Vieira et al. characterized 12 fractions enriched in peptides derived from L. pisonis seeds to determine inhibitory activity against Candida albicans. The fraction that exerted the strongest activity at 10 μg/mL, suppressing C. albicans growth by 38.5% and inducing a 69.3% loss of viability, was identified as similar to plant defensins and thus dubbed “L. pisonis defensin 1 (Lp-Def1).” The investigators concluded that Lp-Def1 acts on C. albicans by slightly elevating the induction of reactive oxygen species and causing a significant reduction in mitochondrial activity. They suggested that their findings support the use of plant defensins, particularly Lp-Def1, in the formulation of antifungal products, especially to address C. albicans.10
Pruritus
In 2012, Silva et al. studied the antipruritic impact of L. pisonis leaf extracts in mice and rats. Pretreatment with the various fractions of L. pisonis as well as constituent mixed triterpenes (ursolic and oleanolic acids) significantly blocked scratching behavior provoked by compound 48/80. The degranulation of rat peritoneal mast cells caused by compound 48/80 was also substantially decreased from pretreatment with the ethanol extract of L. pisonis, ether-L. pisonis fraction, and mixed triterpenes. The L. pisonis ether fraction suppressed edema induced by carrageenan administration and the ethanol extract displayed no toxicity up to an oral dose of 2g/kg. The investigators concluded that their results strongly support the antipruritic effects of L. pisonis leaves as well as the traditional use of the plant to treat pruritus.2
Stability for Cosmetic Creams
In 2020, Rampazzo et al. assessed the stability and cytotoxicity of a cosmetic cream containing sapucaia nut oil. All three tested concentrations (1%, 5%, and 10%) of the cream were found to be stable, with an effective preservative system, and deemed safe for use on human skin. To maintain a pH appropriate for a body cream, the formulation requires a stabilizing agent. The cream with 5% nut oil was identified as the most stable and satisfying for use on the skin.7
More recently, Hertel Pereira et al. investigated the benefits of using L. pisonis pericarp extract, known to exhibit abundant antioxidants, in an all-natural skin cream. They found that formulation instability increased proportionally with the concentration of the extract, but the use of the outer pericarp of L. pisonis was well suited for the cream formulation, with physical-chemical and organoleptic qualities unchanged after the stability test.11
Conclusion
The available literature on the medical applications of macadamia and sapucaia plants is sparse. Some recent findings are promising regarding possible uses in skin health. However, much more research is necessary before considering macadamia and sapucaia as viable sources of botanical agents capable of delivering significant cutaneous benefits.
