Traditional sunscreens only protect from UV rays, offering just partial protection. But our skin is always exposed to both sun AND pollution, which cause free radicals within the skin that can lead to skin damage and premature aging. Powered by EnviroScreen Technology, Colorescience Total Protection formulas, including Face Shield, provide all-mineral, broad spectrum SPF 50 defense against UVA/UVB, pollution, blue (HEV) light, and infrared radiation.
