acne
"I only started using differin a week ago. It has made my skin very red like in the first 3 days I got a red rash-like thing below my lips and on my cheeks and it burns. It also has made around my eyes very dry. I am going to start using it every second day for my skin to get used to it but I really hope that it will work. Just give it time people and don't over use or get worried if your skin becomes red because that is a side effect if you have sensitive skin."
