acne
"I had the worst skin In my year. It started off small but then went haywire at the end of year seven to the beginning of year 8. Then my mums fabulous Doctor friend  helped me  out on Epiduo! I've never had better skin! I've gone from not being able to touch an inch of clear skin to being not able to touch a fragment of bumpy skin! Epiduo is a life saver. Without it, I don't know what my skin would look like now. 
It didn't really sting my face but if your skin is dry it will. "
