Visible Light and the Skin

Photochemistry and Photobiology, 2022
AbstractVisible light (VL, 400–700 nm) was previously regarded as nonsignificant with minimal to no photobiologic effects on the skin. Recent studies have demonstrated that in dark‐skinned individuals (skin phototypes IV–VI), VL can induce more intense and longer lasting pigmentation compared to ultraviolet A1 (UVA1, 340–400 nm).

Visible lights and visible light-activated composite resins

The Journal of Prosthetic Dentistry, 1983
U ltraviolet light (W)-activated composite resins serve a useful purpose.‘,* The depth of cure provided by the various UV systems has contributed to their acceptance.3 Recently, the visible light-activated composite resins have gained in popularity. At the start of this investigation, there were 11 visible light-activated composite resins and eight ...

Visible light. Part I: Properties and cutaneous effects of visible light

Journal of the American Academy of Dermatology, 2021
Approximately 50% of the sunlight reaching the Earth's surface is visible light (400-700 nm). Other sources of visible light include lasers, light-emitting diodes, and flash lamps. Photons from visible light are absorbed by photoreceptive chromophores (e.g., melanin, heme, and opsins), altering skin function by activating and imparting energy to ...

Phenylazothiazoles as Visible-Light Photoswitches

Journal of the American Chemical Society, 2023
A novel class of photoswitches based on a phenylazothiazole scaffold that undergoes reversible isomerization under visible-light irradiation is reported. The photoswitch, which comprises a thiazole heteroaryl segment directly connected to a phenyl azo chromophore, has very different spectral characteristics, such as a redshifted absorption maximum ...
