Visible light in photodermatology

open access: yesPhotochemical & Photobiological Sciences, 2020
Until recently, visible light (VL) had been regarded to be without significant photobiologic effect on the skin. Updated research suggests that this is not the case and the measurable effect of visible light on the skin is being documented in all skin types.

Visible light. Part II: Photoprotection against visible and ultraviolet light

open access: yesJournal of the American Academy of Dermatology, 2021
Cutaneous photobiology studies have focused primarily on the ultraviolet portion of the solar spectrum. Visible light (VL), which comprises 50% of the electromagnetic radiation that reaches the Earth's surface and, as discussed in Part I of this CME, has cutaneous biologic effects, such as pigment darkening and erythema.
