Differin
"The first 2 days of using differen gel were a little rough. My skin was super dry and I had to keep caking on the moisturizer. I took a couple days off from use and then started back daily use with no problem. I just moisturizer every morning. My skin still isn't perfect but it at least dries up the lager cystic acne. I still get blackheads around nose and small "under the skin whiteheads" around my chin. But I don't exfoliate like I should so that's my own fault."
