acne
"I had acne for 5 years, saw many doctors and they all said nothing would help me and I would have acne for the rest of my life. I tried many creams, nothing worked. Then a dermatologist prescribed Duac and after about 3 weeks my skin was 100% clear. She told me to use a very thin layer at night and to use a heavy moisturiser in the morning to protect my skin. She also told me to stay out of the Sun at the time as your skin becomes thinner and more sensitive. 
Yes, in the beginning my skin was red and dry, but that goes away after a few days. Thats how you know it's working. It's definitely worth a few days of irritated skin knowing you'll have perfect skin after.
Duac saved my skin. I'm forever grateful!!"
