Proactiv is cheap, relatively speaking. It's about twenty times cheaper than Accutane! But if your acne isn't that bad, you might benefit from antibiotics, which are even cheaper. Keflex and Amoxil are both available in generic froms. When I was in high school, I had perpetual sinus infections and stayed on antibiotics most of the time. I had NO ZITS! My skin was envied. Now it looks awful, but since I recently reverted to a basic course of Amoxil, it has begun to clear again. Good luck!
