This stuff is great! After I used it for 3 weeks, I notice the differences. My skin got smoother, and it seems to me that it really did get brighter. I read some reviews saying that this stuff causes breakouts, and I think that would be the case for people with oily skin, because I have extremely dry skin, and this stuff is moisturizing enough to make my dry, flaky skin super smooth, even my boyfriend noticed the difference. And the good thing is, even though it is very moisturizing, it doesn't feel greasy or sticky at all. This stuff is too expensive for a drug store brand (and the small amount, only 30ml), but I think it was definitely worth it!
