Jawline Definition

Meaning

Jawline Definition is an aesthetic and anatomical descriptor referring to the distinct visual delineation and sharpness of the inferior border of the mandible and the prominence of the gonial angle. A well-defined jawline is characterized by minimal subcutaneous fat, firm skin and connective tissue overlying the bone, and robust masseter muscle volume. This feature is heavily influenced by skeletal structure, body composition, and the underlying hormonal milieu. Clinically and aesthetically, it is a key component of facial attractiveness and a visual cue of androgenic status.
