According to the brand, this next-generation invisible sunscreen is “designed for long days outdoors,” but instead of the thick and chalky formulas of “sport” sunscreens past, Anthelios UV Air has a weightless serum texture that was tested against high heat, humidity and pollution. It’s formulated with hyaluronic acid, glycerin, niacinamide and La Roche-Posay’s key antioxidant technology and famous Thermal Spring Water.
