Jowls, marionette lines, and sagging facial skin are common signs of aging that occur due to collagen loss, gravity, and skin laxity. Jowls form when the skin around the jawline begins to loosen and droop, creating a less defined facial contour. Marionette lines are the vertical wrinkles that extend from the corners of the mouth to the chin, often deepening with age. Sagging skin results from weakened connective tissues and reduced elasticity, making the face appear less lifted and youthful. While natural, these changes can be addressed with treatments that restore firmness and structure to the skin.
