A dimple in the chin is often referred to as a butt chin or beauty cleft, but it actually has a moniker called cleft palate and is a common and hereditary facial feature. It is a common and hereditary facial trait that refers to a dimple or a similarly deep pit in the skin of the lower jaw of people's heads. People with this trait have a striped or almost inverted Y-shaped indentation in the jaw due to the specificity of the underlying bones. |
