Okay let me just say I have been using this product for almost month now and my hyper pigmentation and red marks have faded a little tiny bit. My skin looks better but you will break out some days while using this. I have been having a big problem on my chin. I get huge pimples under the skin and they hurt a lot. I use ice to bring the swelling down. My dermatologist told me to start slow at first and use it 2-3 times a week. I used it 2 times a week for two weeks, then I used it for 3 times a week and now I'm using it mostly every day. He said give it a month until you actually start seeing good results. So far so good just have patience. Btw the acne on my chin isn't from this product it's from hormonal imbalance and I just started birth control because I don't know what else to do.
