Update on photoprotection

Abstract

Photoprotection is an effective method for preventing damaging effects from ultraviolet radiation (UVR). Photoprotection is accomplished through the use of sunscreens, protective clothing, and safe sun practices. Sunscreens are composed of various UV filters, including inorganic/physical blockers and organic/chemical sunscreen agents. New technologies are emerging in sunscreen development and may soon be available to U.S. consumers. General guidelines for sunscreen use should be reinforced to improve patient compliance and sunscreen efficacy. Habitual use of sunscreen is recommended with UV exposure, and concerns for vitamin D deficiency with sunscreen use should not supersede proper photoprotective behavior.
