Adapalene
"I've had acne since like the 7th grade and I didn't really bother to do anything about it because it wasn't bad but at the end of 8th grade it got worse so I went to a dermatologist and she prescribed Epiduo to me and I used it and had clear skin for almost the whole summer, but in August when school started my face started getting horribly dry and peeling and it hurt. So I went back to the derm. and she prescribed Differin (0.3%) gel and I've been using it now for 4 months and it works great! I have to say it does get worse before it gets better. "
