A cleft chin, also known as a dimpled chin, is a distinctive facial feature characterized by a noticeable indentation or groove in the center of the chin. This trait is caused by a genetic variation in the structure of the jawbone and surrounding tissues. Cleft chins can vary in depth and prominence among individuals, making them a unique aspect of facial appearance. This feature is often associated with certain ethnic backgrounds and can be found in both males and females. While some people find cleft chins attractive, others may not have a preference. The presence of a cleft chin is purely a cosmetic trait and does not affect a person's health.
