Um, can anyone say "Complete waste of money"? This was my first purchase of a lip-plumping gloss and when I put it on I waited for the sting. Tingle? Slight numbness? Something? NOTHING! The gloss isn't even of decent quality. It feels like you've doused your lips in petroleum jelly that melts on your mouth- yuck! (And it tastes like liquid petroeum jelly too- ew!) Okay the plumping factor? When your lips are dry or chapped, this can be a decent application (but it's hard to love because of its consistency). It gets rid of the deep lines and makes lips a bit smoother, but does nothing for "fullness" and nothing to create a decent pout. Save your 12 bucks and opt to spend 10 on Sexy Mother Pucker. At least the tingle will fool you into thinking you've got fatter, sexier lips.
