Dapsone
"Never written a review but this product is sensational. Best creme on the market, doesn't irritate skin and very effective for preventing and healing acne. Works well on face but even better on chest/back I found. Just a few heads up. Don't use with any hydrogen peroxide based products(moisturizer creme etc) at this will temporarily turn your skin brown. Also don't apply too much at a time as it takes a long time to absorb(it will be visible for a short period). 



After using accutane I thought that was the only thing that could really help acne but this works almost as well"
