Pear vortex, also known as dimple, is a kind of dimple, but its position and characteristics are different, so there is nothing precious and precious.

When making a "smile" expression, facial muscles touch each other, resulting in a depression called "dimple". Some people call it "laughing nest", or because of its different location and size, it is also called "pear nest". Not everyone has dimples, but people who have dimples also have different shapes and heights.

Under subdivision, dimples are located about 2-2.7 cm above the corners of the mouth, and there are three kinds of dimples: round, oval and fissure. Generally, dimples are the most obvious when you laugh. And there is a nest on the face, called pear nest. The pear nest is located below the corner of the mouth, about 1 cm. Pear nests are smaller than dimples, so they are not clear. The formation of dimples is mainly genetic. It can also be obtained through plastic surgery.

Dent formation

Dimples are formed by muscle activity under the skin. Most muscles of human body are firmly attached to bones through tendon fibers, such as pectoral muscles and lower limb muscles. Facial expression muscles are an exception. It is directly attached to the facial skin. When the expression muscles contract, it will affect the facial skin, so various wrinkles appear on the face, resulting in expressions of joy, anger, sadness and joy.

Whether there are dimples is related to the development of expression muscles. People with less plump smiling muscles and less subcutaneous fat on their faces generally have no dimples when they smile. Of course, dimples can also be made the day after surgery.
