I am going in for my third treatment of fraxel next week (I bought 4 treatments) and I had acne after each treatment. I still have acne and it has been 3 weeks since last fraxel. This is just part of the side effects. The acne should eventually clear up I think. I think it takes four treatments to see any results. So far do not see any improvement but I think after the next 2 fraxels I will. So I will reserve judgment until about 90 days after the 4th (last) facial fraxel to see what I think. The acne is a bummer for sure.
