The regio dagu, commonly known as the chin region, is the most forward projecting part of the face, located below the lower lip. Anatomically, it is supported by the mental protuberance of the mandible (jawbone). The chin plays a crucial role in facial aesthetics and contributes to a person's overall appearance. Various conditions can affect the chin, including acne, skin irritations, and injuries. In some cases, cosmetic procedures may be performed to alter the shape or size of the chin.
