This is nothing more than AIR IN A CAN ! just like what you would use to clean your computer! I tried it and it left me my face with two huge spots, which i spent thousands of dollars getting peels to get spots to go away. It took me more than ONE year to have them lighten up. I e mailed them regarding the spots and how the blemish got worst and all they said was that i was one of the one percenters that it didn't work on. I tried it on my boyfriend and he still has the spot to this day, I tried it on a non visible area. But this is a total scam and is not worth the price! it's expensive when you buy it and yet continues to be expensive with all the treatments that you have to get to make spots dissappear. I couldn't go out i was in tears !! it was horrible what this product had done to me. DON"T USE IT!
