I also must agree with the other posts. Differin really didn't do anything. I mean it did cause the "inital breakout" as it is suppose to. But after that it did nothing. The breakout didn't get better or worse. Just said the same really. Also made me quite oily. (And I already have oily skin!) But everyone is different. I know a few people who have used Differin and it worked for them. So give it a shot... if you don't see improvement after 6 weeks... consider switching meds (like I had to do) good luck!
