Hello...im an african with black skin...a have pimples on my temple and my cheeks.will benzoyl peroxide bleach my skin if i apply it on ...??

BenPeroxide and skin: No, this should not cause a problem with your skin pigment. It may, however, piss off your girlfriend or wife if you get it on your clothes or pillow-case!

Metrogel topical gel: is another alternative if you don't get the desired results with benzoyl peroxide. Metrogel contains an antibiotic, metrodinazole, and is available by prescription. The ointment is mildly astringent but will not cause the drying out of your skin that can result from the use of benzoyl peroxide.

Probably not: To my knowledge, benzoyl peroxide treatment of acne doesn't bleach skin -- but I'm not a dermatologist, not certain. However, this may not be the right question. In dark skinned persons, any scarring can be depigmented, i.e. light color. Your acne itself carries more risk of this than treatment does. Severity of acne can be easily controlled, e.g. with low dose antibiotic. See a dermatologist.
