Can you tell me how to get rid of moderate acne?

Serious Rx: I trust you are already using topical benzoyl peroxide as tolerated and this has not cleared you. Your physician needs to add something else. If it's on your trunk, a month on an antibiotic may be all that's required; repeat occasionally as needed. Acne can't be cured but will eventually remit on its own. Isotretinoin is available for the toughest cases. Best wishes.

See a dermatologist: Very important to know menstrual history and any birth control. Nursing? Pregnant? Best treatment for most women your age is spironolactone, typically 100mg a day. Not to be used if pregnant, nursing, or kidney failure. Costs only $16 for 3 months, works in 2 or 3 months, then is continued to keep it controlled. It is an anti androgen which might make your bra tight.
