Facial aging

Sažetak
Facial aging results from cumulative age- related changes in the skin, soft and skeletal tissues of the face. Its manifestations reflect combined effects of gravity, facial volume loss, progressive bone resorption, decreased tissue elasticity, and redistribution of fat. Despite widespread interest (e.g., in facial reconstruction, facial recognition, aesthetic rejuvenation), thorough quantifications of facial shape changes with advancing age remain scarce. Therefore, surface scans of 88 human faces (aged 26–90 years) were analyzed via geometric morphometrics. The 32 men and 56 women were from the coastal town Split and the neighboring islands Korcula and Vis (Croatia), exhibiting considerable genetic and environ-mental homogeneity. Forty fixed landmarks and 554 curve- and surface-semilandmarks were used to regress facial shape upon chronological age. Male and female distributions barely overlapped. Their – close to linear – age trajectories were almost parallel, until around age 54 when the female trajectory turned sharply, likely resulting from menopausal hormonal changes. In both sexes, increasing age led to a flattening of the face as well as an overall sagging of soft-tissue resulting in a “broken” jaw-line, deepened nasolabial folds, and smaller visible areas of the eyes. Further characteristics of advanced age were relatively thin lips, a drooping tip of the nose and lengthened ears. Enhanced longevity in older ages is a main contributor to projected gains in life expectancies at birth, which doubled across industrialized countries over the last 200 years. This emphasizes the importance of understanding age dependent changes in facial morphology in older age together with their social perception.
