Cutaneous pigment responses to ultraviolet radiation are outlined in this article. The responses induced by different wavebands are compared, and the protection against further exposure that is conferred by different types of tanning is discussed. The term "tanning" is used here to denote the spectrum of adaptive changes in the skin resulting from ultraviolet exposure and is not applied exclusively to increased melanin pigmentation.
本文概述了皮肤对紫外线辐射的色素反应。比较了不同波段诱导的反应,并讨论了不同类型晒黑所提供的对进一步暴露的防护作用。这里使用的“晒黑”一词是指皮肤因紫外线暴露而产生的适应性变化谱,并不专门用于指黑色素沉着增加。
