Dimples are caused by the underlying muscle structure in the cheeks and are not directly related to the amount of fat in the face. However, if a person has excess facial fat, it may obscure the appearance of dimples or make them less noticeable. In such cases, losing weight and reducing facial fat through diet and exercise may help to enhance the appearance of dimples.   On the other hand, if a person has a naturally lean face with well-defined facial features, their dimples may be more prominent and noticeable. The appearance of dimples can also be enhanced through cosmetic procedures such as dimpleplasty, which creates artificial dimples on the cheeks through a surgical procedure.
