Etymology: Photoaging is a straightforward compound: "photo-" comes from Ancient Greek "phōs" (genitive "phōtos"), meaning light, and "aging" is the ordinary English word for growing older. Put together, the term names the gradual deterioration of skin caused by repeated exposure to sunlight rather than by the passage of years alone. The Greek root reaches far back. It traces to a Proto-Indo-European base meaning "to shine," which gave Greek a family of words for light, and English later borrowed the combining form "photo-" to build terms connected with light and photography. Photoaging adds that light-related prefix to a plain English word, so the name states its cause directly: the aging is driven by the sun.

Synonyms: photodamage, sun damage
