It has been well established in both human and animal skin that ultraviolet radiation from both ultraviolet B (UVB) (290 nm-320 nm) and ultraviolet A (UVA) (320 nm-420 nm) can produce profound changes in the skin that with recurrent exposure, cause it to become what we recognize as photoaged skin. Experimental studies in animals have confirmed that some sunscreen chemicals are capable of providing protection against ultraviolet-induced photoaging. It is presumed that regular use of these effective sunscreens will also reduce skin aging changes in humans.
在人类和动物皮肤中都已明确证实，来自紫外线B（UVB）（290纳米 - 320纳米）和紫外线A（UVA）（320纳米 - 420纳米）的紫外线辐射会在皮肤中产生深刻变化，反复暴露会导致皮肤变成我们所认知的光老化皮肤。动物实验研究证实，一些防晒化学品能够提供针对紫外线诱导的光老化的防护。据推测，经常使用这些有效的防晒霜也将减少人类皮肤的老化变化。
