Getting rid of/Preventing the 'Double Chin'

Let's face it...we all know a ton of different ab exercises as well as various routines to get our bodies in shape ...but do you know any exercises off the top of your head that focus on the "double chin" area? I found a few simple exercises that help firm up & to prevent and/or get rid of the infamous double chin.

The exercises and information provided are from http://facialexercisesguide.com/8/how-to-get-rid-of-double-chin-3-double-chin-exercises/ :)

"Exercise 1

While standing up, pull your head slightly back such that your face is tilted towards the ceiling.
Now try to kiss the ceiling by stretching your lips and puckering up. Hold for five seconds. Repeat five times.
Remember to leave the other facial muscles that are not engaged in this exercise as relaxed as possible.
Exercise 2
This exercise can be done on a seated or standing position. Pull your spine straight up and leading with the chin, gently rotate your head from one shoulder to another.
Do not hurry while performing this exercise, and make only slight, precise movements. Work your way to doing full head rolls. Stick to semi circular motions if full circular rotations bother your neck. Do a full roll three to five times."
