I have received this product as a sample. With a few scars and tiny dark spots on my face I have decided to give it a try. I have been using this now for 2 weeks and all the spots I have started working on are now clear. I was very skeptical at the beginning because there are millions of products that sells us all dreams. But this product is by far the best I have tried and has actually worked. Highly recommend this to anyone with acne scars and dark spots.
