Yup...this totally works! I used to do it when I had pretty bad acne years ago. Although, I think I took a 100mg supplement. Zinc is one of those things you have to be careful how much you take though, because it can build up in your body and become toxic. But...I never had a problem with 100mg. I think you'd have to really be mega dosing for it to be a problem. My stepmom, who is a big health nut, told me about it at the time. You have to give it a little time to work though. It was not an immediate improvement. It took a few weeks if I remember correctly.
