Differin
"I started getting acne in my early 20's and by 27 I was suffering from cystic acne.. In total I'd say I've tried 20 or more treatments without improving. I did two courses of accutane without improvement... about a year later I went to a new dermatologist and was prescribed differin gel. After three months my face was perfect.. no acne, no scars. Don't even judge it for two months... waiting isn't fun but discouragement can lead to quitting... don't quit you won't regret it... my skin did get dry and sensitive but got better within a month or so... don't scrub, use excessive products and use moisturizer... seriously perfect skin!!"
