Sometimes beauty is just plain strange.

The Beauty Smile Trainer, a Japanese invention, is basically a mouthpiece, but it’s designed specifically to make your smile wider, more symmetrical and more amicable than the one you already have… apparently!

It’s even endorsed by a cosmetic dentist (the woman on the top right) In addition to improving your smile, the product promises to reduce facial sagging, making your complexion firmer and perkier.

Oh erm, if they say so!
