Implications of visible light and means of photoprotection

Abstract

Visible light (VL) has been shown to promote genotoxicity through free radical generation and structural protein degradation. These stressful events promote cellular vulnerability, which manifests clinically as erythema, hyperpigmentation, and photoaging. Having established biologic impacts of VL, development of photoprotection strategies against this part of the solar spectra are warranted. This invited review presents advances in the VL literature and discusses available and potential means of VL photoprotection.
