1. Pinch the excess fat in the mandible with your thumb and forefinger and pinch it backwards. Pinch it every one centimeter. When pinching the root of the ear, repeat pinching for 5 times. This can improve the overall contour of the face.

2. Grind your teeth slightly and press the ear root acupoint with your thumb for 5 seconds.

3. Separate the index finger from the other fingers, and wipe it from the ear root to the center of the mandible according to the contour of the mandibular face with the left and right hands.

4. Put your fingers together and pull your hands alternately from neck to jaw. This action is very helpful for thinning the chin.

Stick to it for 45 days and you will see obvious results. I hope I can help you.
