Why do some people have dimples and you don't?

The charming dimpled cheeks create a youthful definition, the dream of many people, especially girls, but not everyone is lucky to have. So why only some people with dimples, due to genetic factors or other causes?

In scientific terms, the fact that dimples are a minor defect of the cheek muscle during fetal development. During the embryonic stage, the human cheek muscle appears to have a defect that causes the muscle between the cheek and skin to stick together. When people laugh, the active muscle shrinks the skin inside to form a small dent that we often call dimples.
