a search will clear this up (no pun intended) it can help and maybe eliminate acne, it needs to be taken a few months before. I and many others have used it while on cycle with great results. Its expensive and does have side affects of its own though. If you are acne prone it might be a good idea, if you do it while on cycle make sure and go through a doc or at the very least get blood work (and analysis) monthly while on, its important.
