EltaMD UV Sheer Broad-Spectrum SPF50 sunscreen provides excellent and UVB (burning) rays. It is water-resistant (80 minutes) and sweat-resistant. This sheer facial sunscreen, physical/chemical combo formula, with SPF 50 is a lighter, fluid-like formula that allows for rapid rub-in application without any white cast. When applied, it goes through a water break, creating a sheen-like look at first. It then immediately absorbs into the skin, leaving a matte finish and helping to even skin tone. The sheer formula is hydrating yet not greasy and helps to calm heated/red skin. Antioxidant protection combats skin-aging free radicals associated with ultraviolet (UV), infrared radiation (IR) and offers high-energy visible (HEV) light protection. The formula is dye-free, fragrance-free, oil-free, paraben-free and alcohol-free.
