I like the product feel and use it like I would a moisturizer with an emphasis on the problem areas with brown spots, which sadly is most of my face. I like the feel of it and the light tingling of it keeps me hopeful that it is in fact doing something to work on these spots. I'll continue to use my initial 3-bottle supply to see if I can determine results and then go from there. I'm hopeful.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
