Differin
"My acne was moderate, I went to the doctor and tried birth control to help & the first 3 months on birth control made it 100 times worse, I stuck with it though & then got on a prescription topical which I had an allergic reaction to. I tried so many different face washes, then finally a family friend recommended differin. I found it  for $20-25 I think? My skin cleared up in a week. I still have some small under the skin spots around my chin / mouth but easily covered up by make up. No more cystic acne! I recommend everyone to try this. I have before and after pictures that I wish I could attached because the difference is insane."
