摘要
人体的皮肤每天都接受来自日光中紫外线的辐射，其长期辐射可导致皮肤光老化。近年来，随着空气污染所致的臭氧层变薄，紫外线更易通过大气层，从而加重暴露皮肤的光损害。皮肤光老化可与多种皮肤病甚至与皮肤肿瘤的发生有密切关系，本文主要描述了紫外线造成的皮肤光老化及其机制。
Human skin exposed under the daily sunlight from the uhraviolet UV radiation, and its long-term radiation can lead to Photoaging. In recent years air pollution is causing the ozone layer thinned, more ultraviolet radiation went through the atmosphere, and increasing skin damage. Skin-aging are demonstrated to be closely related to a variety of skin diseases and the incidence of skin cancer. This article summarized the photoaging caused by UV radiation and its mechanisms.
