June 2018 in “Proceedings of the National Academy of Sciences of the United States of America” This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.
April 2018 in “Journal of Investigative Dermatology” This study found that external light can rapidly activate hair follicle stem cells in animals via a retinal light-sensing pathway linked to the central and autonomic nervous systems.
March 2024 in “Antioxidants” This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.
