Facial aging is a multimodal process that consists of three factors: the loss of elasticity of the superficial musculoaponeurotic system (SMAS, representing the major tissue-supporting facial structure); the skin itself, which is exposed to daily environmental strains and stresses; and the tendency of volume deflation and tissue repositioning following continuous gravitational exposure. 1, 2, 3, 4 Each of these three factors contributes to the overall appearance of aging, with various physical changes such as wrinkles, sagging skin, and volume loss.
