This superfancy tool delivers an immediate improvement to under-eye bags and puffiness. It is made with "artisan glass techniques," and the two orbs (they kind of look like luxe thermometers) have no seam. This means they can be rolled and smoothed over your face and eyes without scratching the skin. Place them in the fridge (do not freeze!) for 30 minutes, then go to town. Watch this handy tutorial for instructions on how to use it for maximum effect.
It is a bit pricey, so if you like the concept but can't shill out the dough, this budget buy from Hansderma is a good option. While you shouldn't use it on your eye area, it is a great way to smooth out lines and make your skin look brighter, tighter, and more energized.
