Photosensitization may be defined as a process in which a reaction to normally innocuous radiation is induced by the introduction of a specific radiation-absorbing substance (the photosensitizer) that causes another component (the substrate) to be changed by the radiation. This review focuses on photosensitization produced by exogenous chemicals. Idiopathic photodermatoses, including polymorphous light eruption and its variants, solar urticaria and chronic actinic dermatitis, are also discussed. Clinical recognition patterns of the photodermatoses are stressed as well as several diagnostic procedures available for confirmation of the condition. Finally, descriptions, therapeutic uses, and adverse reactions of sunscreens are provided.
通过引入一种特定的吸光物质（光敏剂），引发对通常无害辐射的反应，该光敏剂会使另一种成分（底物）因辐射而发生变化。本综述聚焦于外源性化学物质引起的光致敏作用。还讨论了特发性光皮肤病，包括多形性日光疹及其变种、日光性荨麻疹和慢性光化性皮炎。强调了光皮肤病的临床识别模式以及可用于确诊该病的几种诊断方法。最后，介绍了防晒霜的描述、治疗用途和不良反应。
