I would advise to give it several treatments before coming to a verdict. I do experience breakouts sometimes after sessions, especially in the beginning of treatment and if I miss a a month or two of maintenance. But they quickly heal in just a couple of days leaving unbelievable blemish free skin. I have been using antibiotics and topicals for the last several years, and Isolaz for the last year or so. This is the first time in my life I can actually skip makeup if I want!!! I have had acne since age 10.
