It stings awful and I thought it was normal, but it also doesn't really moisturize! I was happy with cleanser and peroxide but decided to try the Glycolic Acid moisturizer instead: day and night! It actually works. I decided to give this one another try since I had a whole bottle left - NOPE! Still stings like hell - threw it out!
Right now, I use acne cleanser, peroxide, Glycolic acid moisturizer (works great) + 2-4 capsules of 500mg of Panthothenic Acid. I still have occasional break outs BUT considering how bad it was, I consider this a miracle. All of my friends tactfully notice that my skin has gotten so much better, although I still have all the scars! I'm working on it now but at least there is some light at the end of the tunnel!
