Why do people have dimples?

Dimples are a genetic defect that causes facial muscles to pinch causing the indentation. Dimples are genetic, which means that they are inherited from the parents.

Dimples are an indentation on the skin. Technically, dimples are actually any indentations on any part of the body, including the legs and the back. However, the most popular forms of dimples are the one that occur on the cheeks. In fact, the cleft chin is caused by a dimple on the chin.

Dimples are generally considered to be attractive in most cultures. However, what actually causes dimples? According to most theories, dimples are a genetic defect. Dimples are caused by a deformity in the zygomaticus major, which is a facial muscle. When the zygomaticus major is shorter than it should be, they tent to pull on the surface skin when the person smiles. This causes the appearance of the dimple on the surface.

The zygomaticus major develops when the baby is still in the womb. Hence, the deformity also occurs there, as chances are that the muscle is underdeveloped. However, if the muscle develops over time, then it is possible that the dimple will go away. This is the reason why some children loose their dimples as they grow older.

It is more common for the dimples to occur on both sides of the face. It is rarer, but still possible for dimples to occur on one side of the face. The dimple on the chin, i.e. cleft chin, occurs when the zygomaticus major from both sides of the face don’t connect properly over the chin. This in turn pulls on the surface skin of the chin creating the cleft chin.

Dimples are genetic, which means that they are passed by parents to their children. According to a study, if one parent has dimple, then the likelihood of the child having dimples is any where between 0 and 50%. While, if both parents have dimples, then the likelihood of the child having dimples is between 50% and 100%. It is also possible for dimple to skip a generation.

Most people consider dimples to be genetic traits caused by muscle defects. However, some scientists now believe that that may be just one part of the puzzle. These scientists claim that there could be many other factors that cause dimples. This could include a mutation in the facial muscles. Newer studies point to the fact that dimples may actually appear and disappear over time and are in fact influenced by various genes.

Dimples may also occur when a person has a little too much or too little fat on their face. This fat can interfere with the zygomaticus major muscle causing the pulling of the muscle to cause the dimple. If the person gains or loses the fat in the face, then they may lose the dimple as well. Due to the perceive attractiveness of dimples, many people seek to artificially create dimples with the help of makeup, glue, and even plastic surgery.
