Never taken those pills, but I had some vicious acne starting when I was 16. It was horrible cause I had the cystic type which cause large nodules under the skin. Inflammatory acne sucks ass.
I'm 21 now and I think I'm almost out of the acne stage. Starting 2 years ago, I started to use Proactiv, and that seemed to work pretty well. My mom noticed my skin got clearer 2 or 3 days after first use. I stopped using Proactiv about 3 weeks ago and haven't broken out since. Could be that I just grew out of it. Anyways, many many ppl get acne so don't let it get to you too much. It got to me a lot and I regret having a skin condition get to me so much. Good luck!
