1. Facial exercise

Facial exercises are the best way you can do to get your chin slim down, they give your muscle of the neck a good workout so you can finally kiss the double chin a goodbye.

The simplest one is to move your lower jaw back and forth, do it ten times.

Then stick your lips out in an "O" shape, and hold them in the position for 5 seconds, do it 5 times.

Do it everyday and you will see the change of your look.

2. Face mask with egg white

You'd better use a facial mask with a lifting effect. Or you could massage upward motion and let it dry. Do it 2-3 times a week and be sure keep your head up when you do it.

3. Chew a mint leaves or gum

Chewing is definitely helpful in getting rid of the double chin, so get a sugarless chewing gum in the grocery store nearby and do it now.

4. Gain a good posture

Yes, this is almost the most important thing. Hold your shoulders back and hold your head up. Look straight and tilt your head up a little bit. You'll see a major difference and you may even not see your double jaw if you gained this good posture.

5. Don't look down on your phone for too long

This is a bad habit that almost everyone have, but the gravity will not only get you a double chin, but also loose your skin on the face. I know it's too hard for everyone to carry out so you can find something to hold the mobile phone for you, such as a phone holder, so you can watching and play with your phone without let your head down.
