Adapalene / benzoyl peroxide
"I had HORRIBLE acne since I was 13+. I've been using EPIDUO since I was 16 and I can't go without it! I'm now 18 and I've never stopped using it. It's amazing. At first you will be very irritated and your skin gets super dry. But give it a week or 2 and you'll be fine. Your skin adapts and after that it's great. I don't know what I would do without it because there have been times where I stop using it for about a month or 2 and my acne starts coming back. So I guess I'll be using this the rest of my life lol. I get so many compliments on my skin since I've been using this product, everyone asks me what I do."
