Photoprotection: Key Concepts, Current Status, and Special Patient Groups

Abstract

This article aims to help non-dermatologist medical professionals regarding the current status of photoprotection so that they may be better positioned to advise and respond to their patients. While the effects of solar radiation have long been known to include sunburn and skin cancers derived from ultraviolet B radiation, advances in knowledge now recognise the relevance of ultraviolet A, visible, and infrared light as significant contributors to skin damage. Effects on the skin range from aesthetic signs of photoageing, which accumulate with daily exposure, to skin cancers. Despite some trends towards increased awareness of the dangers of solar radiation and the need for photoprotection, behaviours still put people at risk and sun protection is suboptimal. In addition to the general population, certain population groups require special consideration depending on their work environment, lifestyle, and health status. The efficacy and cosmetic properties of sunscreens have improved greatly and should help to improve compliance with recommended use, but a multifaceted approach focussed on education and enabling uptake of recommendations is essential.
