I am 20, and when I was a teenager my acne was not bad. Now here recently, like a week before my menstual cycle I break out bad. I'm using OTC treatments and that does help some, but I'm wondering if there is like a vitamin or something I can take around that time to prevent it? I'd rather not go on the pill, but I would like something else to just boost my acne prevention when I know it's coming so I don't break out. I'm still trying to fight off the scars from 6 months ago, I don't want any more breakouts!
