The aging process of the skin can be divided into intrinsic and photoaging. Clinically, naturally aged skin is smooth, pale and finely wrinkled. In contrast, photoaged skin is coarsely wrinkled and associated with dyspigmentation and telangiectasia. Although the population of Asia is more than half the population of the Earth, no well-designed study has been undertaken to investigate the characteristics of cutaneous photodamage in Asian skin. As Asian skin is more pigmented, the acute and chronic cutaneous responses to UV irradiation seen in brown skin differ from those in white skin. The clinical characteristics of photoaging in Asian skin, such as pigmentary changes and wrinkle patterns, differ from those of Caucasian skin. This review provides an outline of the characteristic features of photoaging on the brown skin of Asians.
皮肤的老化过程可分为自然老化和光老化。临床上，自然老化的皮肤光滑、苍白且有细纹。相比之下，光老化的皮肤有粗皱纹，伴有色素沉着和毛细血管扩张。尽管亚洲人口占全球人口的一半以上，但尚未开展精心设计的研究来调查亚洲人皮肤光损伤的特征。由于亚洲人的皮肤色素沉着较多，棕色皮肤对紫外线照射的急性和慢性皮肤反应与白色皮肤不同。亚洲人皮肤光老化的临床特征，如色素变化和皱纹模式，与白种人皮肤不同。本综述概述了亚洲人棕色皮肤光老化的特征。
