It took me a while before I even considered vitamin supplements as acne treatment. It just never crossed my mind until I saw these reviews about six months ago.
Zinc seemed to be the most popular, so I initially tried that. It seemed to work alright, but I was still getting minor breakouts and it sometimes left me feeling sick. It also made my eyes really dry which is annoying with contacts.
I stopped Zinc, then tried B-5, and within a couple weeks, my acne was completely gone. My face hasn't been entirely clear since I was 12, and I'm 21 now. I truly can't believe how well this works, and I was such a doubter of vitamin supplements in the beginning. As long as I also wash my face with a simple cleanser every morning and night, I never see a single zit. No more skin toners or Benzoyl Peroxide. Also, I went on Accutane when I was 15, and this stuff does the exact same thing with absolutely no side effects. Amazing.
The only unfortunate part is that, because of the amount you need to take, it can be expensive. I end up spending $70-80 a month on two orders of 300 capsules. I take eight in the morning and eight at night, so 8 grams daily. This is probably overkill though, and I'm going to experiment with lower dosages.
