Dapsone
"I have suffered from cystic acne for almost 10 years. I've tried every topical known to man and not one, but TWO rounds of Accutane. But it still comes back.



I started using Aczone once a day (at night) with a basic moisturizer and have noticed a phenomenal difference. It hasn't healed me because when I'm lazy refilling my prescription, my skin breaks out again. But at least I know it's working when I do use it.



Only downside: it's expensive! Ask your derm for a coupon!"
