This stuff is pretty cool. Though usually not a huge fan of plumping products, this one definitely works well. Of course the effects are not permanent and are best seen for the hours after you put it on (or, in this case, sleep with it on and wake up in the morning) but presents a good alternative to expensive (silly) cosmetic surgery. You can feel it working, too, as the lips get tingly and tight but not uncomfortable. The price tag is steep, but hey it is always good to experiment, and you can always return it if you dont like it!
