Do you think all your efforts at fighting the effects of gravity as you age are in vain? Well, apart from Botox and other non-natural methods such as going under the knife for a little nip/tuck, the Houreisen Face Exercise Mask could be a last resort. It costs just $8 and intends to make you look as though you were the Joker. How does it work? It apparently tighten ups those sagging cheeks whenever you fasten the straps behind your ears, giving your face muscles a work out. All it takes is for you to open and close your mouth for ten minutes each day before results become noticeable – yeah, right!
