I personally use this product for my acne. My sister also uses it. She has been using it for almost a year now. I have only been using it for about three works. It has already cleared my acne. I have sensitive skin. I also sweat alot. I play tennis, basketball, and softball. For softball I am a catcher, the sweat just sits on me. We both have found great success in this product. It comes in a 60 pack bottle. We take it daily. I have very acne prone skin and nothing else works. I look like i should be on a proactiv commercial or something.
