Impact of High-Energy Visible Light on Skin Appearance
Skin photodamages are well documented for Ultraviolet (UV) part of solar spectrum. However, contribution of other components of solar spectrum like visible light (VL) is not well established. The fact that VL contributes a larger portion of solar spectrum (45%) and has multiple artificial sources, compels for more studies to understand its skin impact. Here we share our key findings on the effect of exposures of skin to VL.
The studies indicated signs of skin photodamages with VL. There are compromises in skin-health related parameters: decreased oxidative defense, altered inflammatory response, color and hydration in VL-exposed-skin. The data also indicates blue region of the VL as a major contributor of skin damages.
