April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that low-dose blue light (453nm) may positively affect hair growth by interacting with the receptors CRY1 and OPN3 in hair follicle cells.
September 2017 in “Journal of Investigative Dermatology” In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.

September 2022 in “Journal of Biophotonics” This study analyzed clinical and histological reports and concluded that blue light therapy is safe for human skin, with potential photoprotective effects against UV irradiation due to its impact on skin pigmentation mediated by Opsin-3.
March 2024 in “GSC Advanced Research and Reviews” This study observed that exposure to different wavelengths of light affects opsin and clock gene responses in skin cells, suggesting potential therapeutic approaches using photobiomodulation for dermatological conditions like psoriasis and wound healing.
