Facial Slimming? Cheek Training

A training method that's said to slim the face area. Fill your mouth with water, and rapidly inflate and deflate only your left cheek 40 times, performing the maximum and minimum movements. Do the same for your right cheek, only using your right cheek to puff out and suck in. Do this rapidly 40 times. Do the same for the area above and below your mouth. Instead of doing left and right together, or top and bottom together, do each side individually. For example, just the left side. It seems doing it powerfully and rapidly is best. Also, you don't necessarily need to hold water; air works too, apparently. When you do it, your neck might get sore, and you'll feel the muscles around your mouth that you don't normally use working intensely. I've been doing this for about a week, and I don't know if it's related, but my forehead wrinkles have decreased. My double chin also seems slightly reduced. It's great that you can do it anytime. When you're bathing or brushing your teeth, if you hold water and do it, it might be good because it freshens your mouth and cleans out debris too.
