Picture of Acne

Acne appears when oil and dead skin cells clog up hair follicles, leading to whiteheads, blackheads, and other blemishes.

Acne medications can help clear up the unwanted skin condition. Over-the-counter treatments containing benzoyl peroxide or salicylic acid may be effective. Stronger treatments containing higher concentrations of active ingredients are available by prescription. Some doctors prescribe antibiotics to treat acne. Acne treatments may take 4 to 8 weeks to work.
