Blue Light Protection, Part I-Effects of blue light on the skin.
Coats JG, Maktabi B, Abou-Dahech MS, Baki G. Coats JG, et al. J Cosmet Dermatol. 2021 Mar;20(3):714-717. doi: 10.1111/jocd.13837. Epub 2020 Nov 28. J Cosmet Dermatol. 2021. PMID: 33247615 Review.
BACKGROUND: Blue light is emitted visible light between the wavelengths of 400 to 500 nm. The main source of blue light is sunlight, but digital screens, light-emitting diodes (LEDs), and fluorescent lighting serve as additional sources. ...
