Please help! what is the best way to wash my face and back and get rid of the acne?

Serious Rx: Acne on your trunk won't respond to anything short of systemic prescription rx. One combination is topical benzoyl peroxide plus oral tetracycline; there are many other possibilities depending on what's right for you. Acne is basically unrelated to washing, hygiene, lifestyle, or most other things, and it's a serious personal and professional liability. Let us clear you up.
