I have pock marks too from acne that I had for about three years. My dermatologist perscribed acutane to clear up the acne, but I was left with pock marks all over my face. She told me to wait about six months after the treatment and begin using tazorac cream...It is an extremely potent benzoyl peroxide cream that you use in small amounts on problem areas. It is extremely drying, so it must be used moderately. I have seen significant improvment in my skin, especially after the first two months. Hope this helps!
