Hi, I have had acne for years. I finally became fed up and was prescribed differin just this week (.3% gel). I have mostly comedonal acne. I was wondering if a salycylic acid peel would help improve my acne? If so, should I avoid the differin the few days leading up to the peel and after? I should also say that I have extremely ''tough'' skin, very oily, not allergic or sensitive to anything. Thanks!
