After I read other customer reviews, I purchased the Dark Spot Diminisher. I used the product twice per day as directed and saw no difference after using the entire bottle. I should have requested a refund but missed the deadline after I used the full bottle. I would not recommend this product. Maybe other customers have better luck with it, but it didn't work for me. I have also bought Untox and saw no results with that product either.
Bottom Line: No, I would not recommend this to a friend
