Acne on the face and back is called acne. The treatment of acne is divided into general treatment and medication according to the severity of the condition. General treatment mainly involves eating less spicy and stimulating foods, fatty and sugary foods, avoiding tobacco and alcohol, and usually not squeezing the damage with your hands to avoid secondary and more serious infections. For mild acne, which is acne with mainly whiteheads and blackheads, topical medication is usually sufficient. The drugs often chosen are retinoic acid cream, adapalene gel or azelaic acid gel, benzoyl peroxide gel, clindamycin gel, etc. For moderate acne, that is, acne with inflammatory papules and pustules, oral antibiotics such as tetracycline, doxycycline, memantine, and roxithromycin are needed to inhibit the inflammatory response and kill Propionibacterium acnes. Also severe acne with nodules and cysts requires oral isotretinoin capsules for a 3-4 month course of treatment.
