Acne
"I&#039;ve been using Differin 0.1 for years now (over 10 years) and swear by it. It keeps big cytic acne from breakout too badly / clears up blemishes and marks fast and most importantly prevents from them occuring in the first place. I have also read its anti-aging... I&#039;m 33 now and people think I&#039;m 26."
