Stings when I apply it and it definitely dries out my skin. Not sure if it helps in preventing acne because I don't have acne-prone skin. Bought it in hope that it will help to control my oily skin but it doesn't do anything. It's just collecting dust in my cupboard now.
I bought this as I thought it may help clear up some spots I have. I usually use Panoxyl, but find it very drying. However, this stuff burns! I have never used Salicylic Acid before, and after using this I don't think I will try again! Certainly not this concentrated anyway. This contains 2% of it, and way too harsh for my skin. It claims to work from day 1, but my skin couldn't handle it. My skin went very red and I had big red marks on my nose too! Glad I didn't get the whole line!
