A lightweight, 100% mineral sunscreen that blends in sheer while protecting against UVA/UVB rays, blue light, pollution, and environmental stressors. ALASTIN SilkSHIELD® All Mineral Sunscreen SPF 30 with TriHex Technology® delivers powerful yet gentle broad-spectrum sun protection in a lightweight formula that absorbs quickly and blends seamlessly into the skin with a transparent, untinted finish. Powered by 19.95% Zinc Oxide, this 100% mineral sunscreen helps protect against damaging UVA and UVB rays while advanced ingredients provide additional defense against infrared radiation, pollution, and blue light. Unlike traditional mineral sunscreens, SilkSHIELD® is designed to feel silky, smooth, and weightless without leaving behind a heavy or tinted finish.  The formula also features ALASTIN's patented TriHex Technology®, a proprietary peptide blend that supports the skin's natural renewal process and helps promote healthy collagen and elastin.
