The jawline is one of the most defining features of the human face. It provides the structural scaffolding for the entire face, shape to the chin and lower face, and a frame for other facial features. An ideal jawline symbolizes beauty, youth, health, vitality, confidence, feminine elegance and refinement, or masculine power and strength.
How Aging and Genetics Affect Facial Shape
Over time, natural aging gradually inverts a V-shaped face—cheeks flatten, nasolabial folds appear, and the sharp, sculpted contours of the jawline and chin sag and become obscured. The widest part of the face now sits at the jawline, creating an overly square lower face with asymmetry, sagging, and hollowness. Genetics can also cause a weak, receding, heavy, or unbalanced jawline.
