Dimples have dominant inheritance. This natural dimple may be caused by cheek muscle defects, and sometimes defects are not necessarily a bad thing.

The future will realize the value of beauty.

The Root of Dimple Facial Muscle Defect: Three Muscles

1, zygomatic muscle: Normal zygomatic muscle starts from zygomatic bone and ends at the fusion of levator oris and orbicularis oris muscle, while variant zygomatic muscle has two tendons or is divided into two muscle bundles, which makes it sag. When we smile, the depression takes on the shape of a dimple.

Function of zygomatic muscle: It is an important muscle to produce a smile.

2. Smiling muscle: it is a kind of muscle with changeable opposite sex, and many fibers formed by this muscle through the surrounding fascia gather in the corners of the mouth. Once this aggregation forms a point connection with subcutaneous fibers, it will promote the formation of dimples.

Smiling muscle function: pull your mouth outward during facial movements, including grinning and laughing.

3, zygomatic minor muscle: from the zygomatic bone, it is often similar to levator labialis and zygomatic major muscle * * *, curling the upper lip and smiling, and expressing contempt, disdain and pride.

Another hypothesis: subcutaneous adipose tissue is a fixed point, and the moving force of the surrounding facial muscles is a moving point, thus pulling the skin, making the skin at the fixed point relatively depressed and forming dimples.

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. The two dimples on the smiling face are formed by the relative influence of facial skin and facial expression muscles such as buccal muscle and smiling muscle.

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.

Some people have dimples. Dominant inheritance means that as long as there is one dominant gene in a pair of genes, certain traits will not be displayed in pairs, such as sharp eyes and double eyelids.
