I tried everything under the sun to get my adult-onset acne under control. I even spent upwards of $500 on dermatologist visits, etc. The antibiotics helped a lot, I admit, but never fully cleared things up. I researched and researched, then finally decided to give something so simple a try and boy was it worth it! Keep in mind, zinc isn't an overnight solution, but I've been taking it for about two months now every other day and my face is totally acne free. I went from 20 or so comedones at a time to getting maybe 1 a week that usually heals pretty quickly. I say that anyone with acne should give zinc a try, especially since it's cheap! Always take it with food; otherwise, you'll get super queasy.
