I use this product and am going to for as long as I have it to see if the product will work in the summer sun. I purchased 3 bottles so I know it will take time to continually fade the spots. I am hopeful that it will prevent new ones. So far I am liking that the one on my nose is hard to see now. I also use it on the back of my hands. There is a large spot on my chest that is harder to fade.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
