1, with different positions: the pear nest is located at the lower oblique side of the corner of the mouth about 1 cm, and the pear nest is located at the lower oblique side of the corner of the mouth about 1 cm, which is smaller than the dimple and not obvious.

2, the size is different: due to different locations, the pear pit is smaller and less obvious than the dimple.

3, the reasons for the formation are different: dimples are formed by subcutaneous muscle activity. Relatively affected are facial skin and facial expression muscles, such as buccal muscles and smiling muscles, and dimples may also be recessive inheritance. Recessive inheritance means that the recessive genes in a pair of genes must be dimpled in pairs. Pear vortex is a kind of dimple, indicating different positions and sizes.
Extended data:
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.
Dimples are divided into three types: round, oval and fissure. Some scholars have investigated, mostly distributed in the cheeks, but also common in the corners of the mouth, zygomatic and chin are relatively few.
The occurrence rate of natural dimples in oriental nationalities is 1: 18, with one dimple accounting for 34.2%, two dimples accounting for 59%, three dimples accounting for 5.6% and four dimples accounting for 5.2%. There were/kloc-0 dimples on the left cheek, accounting for 59.6%. Most dimples appeared on the cheek, and most of them were asymmetrical on both sides.
