Abstract: Methods for communicating risk of skin conditions due to exposure to sunlight and environmental conditions to individuals. Methods utilize geolocation data and environmental data to provide guidance and enable consumers to make informed decisions regarding outdoor activities, healthcare, and skincare. A photopollution metric is a function of ultraviolet index (UVI) and the level of a pollutant such as particulate matter (PM) and enables communication of risk of exposome-induced skin conditions to an individual based on environmental exposure.
