acne
"DO NOT use differin. As a result of using this lotion I developed a horrible red rash on my neck and face. 2.5 months later I am still have to apply hydrocortisone cream twice a day to keep it at bay and can't use any nice foundation or makeup. I have read several other reviews where it has happened to people and spoken to other GP's who have said they wouldn't prescribe it. 



IT IS NOT WORTH IT! Try anything else, but don't use this product."
