I had bad Acne for a number of years, very stubborn no matter what treatment i tried. i got rid of it completely with MSM (methyl sulphonyl methane - theres a forum for it i think). Its basically organic sulphur, detoxes the liver. some people swear by it others dont like it. It cleared my Acne up completely within a couple of weeks and it didnt come back. worth a try.
