I have used ProActiv before and it does clear up the acne. As soon as you go off, it comes back with a vengance! Also, don't even think about going out in the sun, even with sunscreen.....you will be so sensitive to the sun! I put my daughter on it. She also has "exercise induced" acne on her shoulders and forehead and neck. I found a better product that doesn't have the same side affects as ProActiv. Kara Vita is better! Just my opinnion!
