NOTHING you buy at wal mart will cure your acne so forget about that. In the end you will find yourself resorting to Accutane and will be extremely happy with the results. Im in month 4 of a 6 month course and havent had a zit since the first couple weeks i began. Low doses of 40mg a day and now im down to a dose of 20mg ED and still flawless, it has worked on and off cycle. I have had no side effects to speak of since the first few weeks at those doses, i would be cautious of going upwards of 80mg ED, the side effects will no doubt be problamatic. I tried everything you can think of before i took the plunge with the accutane, but it was one of the best choices ive ever made.
