There are no acne treatments specifically for use on dark skin. Acne treatments are generally as safe and effective on dark skin as on light skin. 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. Tropical anti-acne agents such as benzoyl peroxide that have a drying effect on the skin should be used under the supervision of a dermatologist. Benzoyl peroxide also is a strong bleach and therefore must be applied carefully to avoid inadvertent decolorization of a patch of hair, towels or clothing.
Darker skin has a tendency to develop post-inflammatory hyperpigmentation (excessive skin darkening at places where the skin was inflamed). Severe inflammatory acne may result in dark spots. The spots resolve 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.
Removal of acne scars by dermabrasion or chemical peeling may cause temporary lightening or darkening of dark skin in the areas of treatment. Scar treatment should be discussed with a dermatologist or dermatologic surgeon before it is undertaken.
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.
