This is not a cure for acne. It can control acne which has not responded to topicals, peels, and other tradition methods. There are many lasers that can be used for this. You need to discuss with your physician your treatment goals and see how many treatments are needed and when touch ups are needed. I'm a firm believer in treating acne this way but it requires up to 8 treatments with some lasers. Long term relief is achieved in some patients but most require every 3-6 month touch ups.
