I don't know what's going on, but I got this as a sample, have been using it for about 4 nights...and my skin is more even toned, smooth and just clearer....dark spots are going away, red spots are going away...I am 41 years old and can not believe the difference already. I am a cosmetic junkie and have never been impressed by a product so quickly....I can't wait for the 2 week mark. I just ordered a full size today :) I will update in 2 weeks
