How to Treat Acne for Black Skin
Acne treatment for black skin is the same as that for white skin, with some exceptions. Some treatments for acne scars may cause temporary lightening of dark skin. Very dark or black skin may be less well-moisturized than lighter skin, so topicals like benzoyl peroxide that have a drying effect on the skin should be used under the supervision of a dermatologist.
Darker skin has a tendency to develop excessive skin darkening at places where the skin was inflamed. Severe inflammatory acne (cysts and nodules) may result in dark spots. The spots disappear over time; a dermatologist may be able to recommend cosmetic measures to make the spots less apparent until they resolve. Some acne treatments, such as topical retinoids and azelaic acid, may also help fade the discoloration.
Alterations of melanin (dark pigments that give the skin its color) pigmentation such as vitiligo and melasma are not related to acne, but they may be present simultaneously with acne. The diagnosis and treatment of melanin pigmentation disorders such as vitiligo requires a dermatologist with knowledge and experience in treating these conditions.
Many doctors feel that laser resurfacing isn't meant for dark skin because it alters the color of skin too dramatically and unpredictably. Others believe that in the hands of a very experienced surgeon, people with darker skin tones can benefit.
