you might have to see a dermatologist to figure out what the exact causes for your acne is. most OTC brands of acne treatment dont give th best results for people with mild to severe acne. if you get one pimple very few months then those products are great. but ive never found long term success with OTC products. they work for a few weeks and then stop. anyways, i already answered a simular post here: http://www.skincaretalk.com/acne/930-new-here.html
