i feel your pain, i had the same problem. i have adult acne. the stuff the skin doctors prescribe is retinA. the only thing that worked for me is something called natures cure. it is a homopathic remedy that includes herbs. if you go to the search engine and type in "natures cure acne treatment" you will find it.
it has rave reviews, there was more people satisfied than not.
it helped me, its inexpensive and you can buy it at CVS, WALMART, WALGREENS sometimes these stores dont sell it, you can order it online. if you have trouble finding it just email me.
good luck
