A dimple is a small natural indentation in the flesh on a part of the human body, most notably in the cheek. Here are some key points about dimples:

• Genetics: Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples. However, the specifics of how they’re inherited still aren’t clear, and multiple genes could actually influence cheek dimples.

• Muscle: Cheek dimples are the result of a muscle in the cheek, the zygomaticus major, splitting in two. Before birth, this muscle can split into a superior bundle that is positioned above the corner of the mouth, and an inferior bundle, below the corner of the mouth. This splitting creates a hammock sort of effect where skin can hang in slightly between the two bundles. When you smile, the muscles contract and the dimples are more prominent due to the increased skin tension.

• Appearance: Dimples are often considered a sign of beauty and youth, and they are desired by both men and women. They can occur on different parts of the body, including the cheeks, chin, elbow, and buttocks.

• Dimpleplasty: It is possible to get a dimple via cosmetic surgery, which is called dimpleplasty. During dimpleplasty, a small incision is made at the site where the dimple will be. Then, a small amount of tissue is carefully removed. A small stitch, called a sling, is passed through the skin and muscle on either side of the area. This brings the skin and muscle together and creates the dimple.

• Disappearance: Dimples that are genetically inherited will not completely disappear, but they may become less noticeable with age or drastic weight loss. However, dimples caused by excess fat at a site are not permanent and can be eliminated through proper diet and exercise.

In summary, dimples are small natural indentations in the flesh on a part of the human body, most notably in the cheek. They are usually considered a dominant genetic trait, and they can occur on different parts of the body. Cheek dimples are the result of a muscle in the cheek splitting in two, and dimpleplasty is a cosmetic surgery procedure that can create dimples.
