There are eight-character lines on both sides of the mouth.

This is caused by insufficient facial movement, and some people say it is the trace of time. Use the following methods to improve it:

1, move your tongue. When it's okay, turn your tongue around in your mouth, ten times clockwise and ten times counterclockwise, alternately.

2, drums. Drum cheeks alternately from left to right, and the number of times is self-determined, which makes facial muscles feel a little tired.

3, softly "send" L and O ",do 15-20 times, this move can also make facial skin firm.

4. Blow gently with an "O" shape. 50-60 times

5. Chew gum and keep smiling.
