I have had three medium-sized dark spots on my forehead for years. Since I don't have bangs, they are quite noticeable. I have had deep level chemical peels, and every couple of years, my dermatologist freezes the dark spots with liquid nitrogen but they come back. I've been using the Gundry MD Dark Spot Diminisher now for several weeks, and the spots are almost entirely invisible. This product has worked wonders and I am so pleased.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
