I have severe back acne. i treated it before but now it's back. it's i thy and so painful. i forgot the medication i used help !

Benzoyl peroxide 10%: I would try a 10% benzoyl perozide wash or creme for starters on the face and back for one month, apply twice a day. Your skin may get pink and peel a bit, then your new acne should decrease in the second month. The next step would be a retin a (tretinoin) product if you are not happy within the month with your improvement. We can prescribe through a Prime Visit.
