title: Photoaging.
abstract: This article discusses photoaging or premature skin aging from chronic ultraviolet exposure. This is an important cosmetic concern for many dermatologic patients. Clinical signs include rhytids, lentigines, mottled hyperpigmentation, loss of translucency, and decreased elasticity. These changes are more severe in individuals with fair skin and are further influenced by individual ethnicity and genetics. Photoaging may be prevented and treated with a variety of modalities, including topical retinoids, cosmeceuticals, chemical peels, injectable neuromodulators, soft tissue fillers, and light sources.
