acne
"This product is a lifesaver! I use Duac at night in combination with Differin in the morning and Sumadan wash before I apply both, and it has done wonders for my skin. I broke out terribly last year (I was 15 then) with huge white heads and bumps all across my forehead and T-zone, and the occasional chin zit. I began using this in June and by the end of the summer my acne was COMPLETELY gone. Aside from being slightly drying (which is totally fine so long as you use a moisturizer 30 minutes after applying)  this medicine is wonderful. I'd definitely recommend this to anyone struggling with moderate to severe acne, but don't be disappointed if it doesn't work right away like it did for me. Also, the tube lasted me forever! Almost 9 months."
