Zinc Oxide is a mineral UV filter beloved in K-beauty for calm, dependable protection. It both reflects and absorbs UVA and UVB rays, supporting broad-spectrum defense to help shield skin from sunburn and the look of photoaging. Ideal for all skin types—including sensitive—and effortless to layer with daily actives. Modern formulas suspend it in skin-comforting textures for a sheer, wearable finish.
