Facial symmetry refers to the extent to which the left and right sides of a person’s face resemble each other, and it is a vital factor in how we perceive beauty and attractiveness. Facial symmetry serves as a reliable indicator of cognitive aging. Progressive changes that occur throughout life in the soft tissues of the face lead to more pronounced facial asymmetry in older individuals. Symmetrical transformations of aging faces typically enhance their attractiveness. Symmetry, a fundamental principle of nature and design, is expressed through balanced distribution and harmony.
