It's been about 3 weeks now and my face is COMPLETELY clear of acne... still a little oily, but A LOT less oily than before. I think that's how this supplement works... by reducing the oil... I'm not sure why, but it works! I did research each ingredient and all the ingredients either help cleanse or strengthen your various organs. Remember though... I stay away from Sugar and I also added a lot of fiber to my diet. Good luck!
