This product works fantastically. I've used it for 2 years and the lip lines have diminished, even after I smoked for many years (having only quit 6 mos ago). I didn't think it was working the first few weeks, but had paid for it so kept using it. Then I saw that my lipstick wasn't bleeding as badly as before I used it, so used it daily. When I stopped using it, thinking it was a waste because I didn't see any more improvement, then went back a few months later to use up the rest of the tube, I again noticed results within 2 weeks. Now I swear by the stuff. My lines are definitely less than other women my age.
