1. First, sit in front of the mirror and look into your eyes, then lift the upper left eyelid slightly higher than the normal posture, and then switch to the right eye. Repeat 20 times. Be careful not to wrinkle your forehead.

Make your eyes turn left like the hands of a clock, and then turn right. Keep your head and eyebrows still. Complete 4 groups at a time, about 4 times in each group.

3. Wrinkle the muscles on the nose and expose the upper row of teeth. Like a rabbit smelling a carrot. Completed 10 times.

4. Suck your cheek a little hard, make a gesture with your lips forward, and pronounce "one", "nine" and "wood". *** 10 times.

5. Spit out your tongue and keep your chin still for a few seconds at a time. ***20 times.

6. Roll up the tongue, retract the tip of the tongue, then extend the whole tongue forward and lower the jaw. ***20 times.

Yes, but it takes persistence to be effective, and muscles may appear.
