I have used the Dark Spot Deminisher for a few weeks now, and my face seems to look better. My spots were small, so it is hard to really tell how much has improved.
I have a large dark spot on my calf, larger than a quarter, which is getting lighter.
I have to admit that I don't always remember to apply the product twice a day, many days it is only once. I do believe the product works; it just takes time.
Bottom Line: Yes, I would recommend this to a friend
