Photoaging
Photoaging
Photoaging (/ˈfoʊtoʊˌeɪdʒɪŋ/), also known as dermatoheliosis, is a term used to describe the premature aging of the skin caused by repeated exposure to ultraviolet (UV) radiation, primarily from the sun, but also from artificial UV sources.
Etymology
The term "photoaging" is derived from the Greek words "phos" (light) and "geras" (old age), indicating the aging process accelerated by light exposure.
Definition
Photoaging is characterized by wrinkles, rough texture, hyperpigmentation, elastosis, and in severe cases, skin cancer. It is distinct from chronological aging and manifests as coarse wrinkles, laxity, and rough-textured appearance.
Causes
The primary cause of photoaging is exposure to ultraviolet (UV) radiation, which breaks down the collagen in the skin and hinders the natural repair process. This results in the visible signs of aging.
Prevention
Prevention of photoaging primarily involves protection from the sun. This can be achieved through the use of sunscreens, wearing protective clothing, and avoiding the sun during peak hours.
Treatment
Treatment options for photoaging include topical retinoids, chemical peels, laser resurfacing, and injectable fillers.
