Evaluation of Tinted Sunscreens Protection Against Blue Light Using Transmittance Spectroscopy In Vitro Technique

This study's findings suggest that depending on their formulations, commercialized tinted sunscreens exhibit different levels of blue light protection. Given the relative newness of tinted sunscreens, plus a lack of regulatory standards, there is a need for more research developing methods to measure protection efficacy of products against visible/blue light exposure.
