So I have deep pitted acne scars and I was hoping this may help with the appearance of them. I do not see any results. People say that this helps calm their active acne, but my active acne just gets worse. I also tried to use this to fight off blackheads, but my blackheads just keep appearing more and more. So I do not think this really works. I feel a tingling sensation when I do use it, meaning that it is activating and working, but I do not really see any results.
