MIAMI BEACH – When it comes to procedures such as chemical peels, microdermabrasion, and laser therapies, one size doesn’t fit all, and dermatologists should take special precautions when treating patients with darker skin.
Dr. Marta Rendon, a dermatologist in Boca Raton, Florida, said she sees at least two patients a week who are seeking treatment for pigmentary complications that have been caused by prior cosmetic procedures performed by other physicians.
Some she can treat, and some are beyond repair.
"If I were to sum up my presentation, I would tell you that above all, be conservative and don’t be aggressive," especially in patients with ethnic skin, she told her audience at the annual meeting of the American Academy of Dermatology.
Dr. Rendon, who is also the president of the Skin of Color Society, urged physicians to take precautions because with the increasing diversity of the United States, their patient population is only going to get more diverse.
"Do the patient history. Take your time," advised Dr. Rendon. "Find out what their ethnic background is. Ask them about their grandmother, and where they are from."
The second most important part of history, she said, is asking about reaction to prior procedures or surgeries and prior history of postinflammatory hyperpigmentation (PIH).
"Ask them about what they do, what their hobbies are, or if they play a sport," she said. And take into account the season. During warmer temperatures, consider superficial peels and be careful with lasers. Medium peels and laser resurfacing are more appropriate during cooler and cloudier seasons, she said.
Take caution
Dr. Rendon had the following advice for various procedures in ethnic skin:
• Don’t perform chemical peels on patients on tretinoin. Don’t start with a high concentration. Don’t do excessive layers. And don’t combine surgical procedures with peels in the same visit.
• When performing microdermabrasion, don’t be too aggressive to avoid PIH, streaking, and scratch marks. Don\'t perform the procedure too close to the eyes. Avoid extremely sensitive skin and pressure urticaria. And always start with the lowest strength and time interval.
• With fillers, be careful with superficial placement since the colored material can be seen through the skin. Hyaluronic acid is safer, because it’s colorless and less risky to use. Be mindful that severe bruising can lead to hemosiderin. And be sure that all your patients are using sunscreen.
• For laser and light therapies, always do a test spot. Have a solid understanding of laser-tissue interaction. And be prepared if pigmentation problems develop, so that you can treat them early.
Treatment
Aggressive and early intervention is crucial in treating side effects from cosmetic procedures.
One of the keys to prevent hyperpigmentation is UV protection, whether it’s with sunscreens, cosmetics, antioxidants such as topical vitamin C and E, or systemic agents such as chloroquine, fish oil, or green-tea extract, said Dr. Rendon.
Several topical agents can be used to treat hyperpigmentation. They include hydroquinone, hydroquinone combination, glycolic/retinoid/steroid combination, or antioxidants.
Dr. Rendon also listed several combination bleaching agents including hydroquinone 4%, tretinoin 0.05%, and fluocinolone 0.01%; hydroquinone 4% and retinol 0.3%; hydroquinone microentrapped 4% and retinol 0.15%; hydroquinone and glycolic acid 10%; hydroquinone, glycolic acid 10% + and hyaluronic acid; mequinol and tretinoin 0.01%; retinaldehyde and glycolic acid; and compounded hydroquinone 6%-8%.
Niacinamide is one of the cosmeceutical skin-lightening agents that act as a vitamin exfoliant, reducing melanosome transfer. Soy-protease inhibitors and glutathione also have skin-lightening effects. Dr. Rendon also listed several skin lightening products including Melanozyme, Melaplex, Lumixyl (oligopeptide), retinaldehyde, lactic acid, ferrulic acid, and sunscreen.
She said her favorite method of treating pigmentary complications is to combine treatments. For instance, she combines peels with microdermabrasion; peels with laser; microdermabrasion with IPL; and fractional resurfacing with topical regimens. She added that she maximizes the procedures with topical regimens.
The bottom line is aggressive and early intervention for side effects, Dr. Rendon said.
As a result of growing ethnic population, the treatment options for pigmented skin is expanding, but in the meantime, dermatologists should ensure that their procedures are specific and individualized, Dr. Rendon advised.
"There’s no way of predicting who will hyperpigment, unless you take a good history," she said. And remember two pearls to stay out of trouble: Be conservative, and don’t use aggressive techniques.
Dr. Rendon has performed clinical research for and/or served as a consultant for several companies, including Amgen, Aveeno, Galderma, J&J, Neutrogena, and Sanofi-Aventis. She is a global spokesperson for the H&S brand.
