I got rid of some really bad Acne after years of trying everything (apart from Accutane), sill trying to sort health problems form being on minocyclene for 2 and a half years - I finally cleared it totally with MSM, 1000 - 2000mg a day. Gone within a month. I did this while smoking cigarettes and MJ daily, among other things. It's not so bad not doing all that stuff anymore, still able to function musically most of the time ;)
Try the MSM it works (I've given this advice sooo many times here that people are gonna think I'm selling the stuff...)
