Sunscreens, used in the prevention of sunburn and skin cancer, have been commercialized since the 1930s. Their utilization is expanding, particularly in response to photoaging and an increase of skin cancer. However, failures occur in sunscreen use because their efficacy depends on the adequacy of application and utilization. This overview documents issues in sunscreen use and also discusses 2007 FDA-proposed rules to offer possible options for enhanced efficacy and communications to the consumer.
防晒霜自 20 世纪 30 年代问世以来，一直被用于预防晒伤和皮肤癌。随着光老化和皮肤癌发病率的增加，防晒霜的使用范围不断扩大。然而，防晒霜的效果并不理想，因为其效果取决于涂抹是否足量以及使用是否得当。本文综述了防晒霜使用中存在的问题，并讨论了 2007 年美国食品药品管理局提出的法规建议，旨在提高防晒霜的功效，并向消费者提供更有效的信息。
