I have been locked in an acne battle since I was 11 years old. I'm 27 now, and suffered the worst breakout of my life this past summer/fall. My skin has turned dry and sensitive, and anything strong enough to fight the acne turned my skin into burning sandpaper. But THIS STUFF WORKS. I've been using it for about three weeks, and while I did have some initial dryness, my skin has adjusted to it and is clearer than it has been in AGES. I am beyond happy with this product.
