Sunscreen use in photodermatoses.
Photodermatoses are relatively uncommon, but most dermatologists will have to diagnose and treat them at some point. This article highlights several photodermatoses, their common symptoms and possible. Unfortunately, sunscreens marketed in the United States do not presently contain agents that are effective against longer wavelengths. There are agents available in other countries that offer better protection. It is hypothesized that these products will soon be available in the United States. Until such time, clinicians should recommend agents with avobenzones, benzophenones, and the physical blockers titanium oxides. Two other agents, dihydroxyacetone and iron oxide, may also offer benefit in some of these patients.
