Acne
"I started using Differin when I was 12. I was going through puberty and getting the worst acne anyone has ever seen. I saw significant improvements in my skin immediately. On the downside, it dries some parts of my face and has increased oiliness in other parts, so now every morning I wash my face and apply moderate-strength moisturizer. It doesn&#039;t prevent blackheads, and I still get some pimples and boils here or there. Now I am 20 and still apply it to my whole face every night."
