我们中的许多人使用市售的防晒霜来保护我们免受晒伤、早衰和皮肤癌，但它们的作用背后的化学原理是什么呢？本文描述了光能如何与分子相互作用产生激发态，这些激发态的行为，导致紫外线防护的特定途径，以及浓度和吸收之间的关系。提供了用于防晒制剂的物质的结构及其伴随的紫外线吸收区域。本文还简要讨论了防晒产品标签上的“防晒系数”（SPF）。
Many of us use commercially available sunscreens to protect us from sunburn, premature aging, and skin cancer, but what is the chemistry behind their function? This article describes how light energy interacts with molecules to produce excited states, the behavior of those excited states, the particular pathways that result in ultraviolet protection, and the relationship between concentration and absorption. Structures of substances used in sunscreen preparations and their accompanying regions of UV-absorption are provided. A brief discussion of the "Sun Protection Factor" or SPF that appears on the labels of sunscreen preparations is also included.
