Dapsone
"Aczone is amazing!  I am 36 years old and have had adult acne my whole adult life.  As I got older it changed but I had never known a time where I wasn't breaking out somewhere. I've been to dermatologists for years and nothing they gave me ever worked. While my acne was not severe it did make me self conscious.  I went to a new dermatologist a year ago and she prescribed Aczone.  She told me it could take up to 2 months to work but I thought I'd try it. This is seriously the miracle I've been looking for, it started working right away.  I no longer get cystic acne and when I do get a blemish Aczone dramatically cuts down on the heal time, it pretty much makes my acne go away within a couple of days & I haven't had any dryness."
