I'm 15 years old and I've had acne for about 3 years now. I started Epiduo 3 weeks ago. I use it every night. After the first 2 weeks I saw noticeable improvement. My skin was still red and kind of dry but it was smooth in places where it's never been smooth before. I was so happy. Then a few days ago I woke up, washed up face and my skin looked horrible. It looked exactly like it did before I started with Epiduo - pimples in the same places and all red. I don't understand why my acne is suddenly re-appearing after 3 weeks of use.. Is this normal? Should I continue using Epiduo or does this mean that it doesn't work for me?
