The pear nest is located below the corner of the mouth, about 1 cm. The pear nest is smaller than the dimple, which is not obvious. It is also called the laughing nest, which is a traditional symbol of oriental beauty.

We smile when we make facial expressions. If facial muscles (zygomaticus maximus, zygomaticus minimus, laughing muscles) interact with each other and produce depressions, it is a "dimple". However, 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 3 cm above and below the corners of the mouth, and there are two kinds of dimples: round and linear. Generally, the concave hole is the most obvious when smiling.

The main difference: the dimple is located within about 3 cm above and below the corner of the mouth, and the pear nest is located about 1 cm below the corner of the mouth, which is smaller than the dimple and not obvious.
