"The Beauty Smile Trainer is basically a mouthpiece, but it's designed specifically to make your smile wider and more amicable than the one you already have. It's even endorsed by a cosmetic dentist (the woman on the top left.) In addition to improving your smile, the product promises to reduce facial sagging, making your countenance more firm and petite."

All I can say is that NO ONE can smile the wrong way as shown on the packaging, it's simply impossible. So nice Photoshop work!
