OIL-FREE POWER. This very water-resistant, broad-spectrum physical block is ideal for extreme exposure. We love it because it’soil-free, great for kids and it dries clean and clear (unlike some physical blockers). Like other products in MD Skincare’s unique collection, it contains an ironencapsulating chelator, which removes iron residue left on the skin by tap water and perspiration, to provide additional sun protection. Plus, it contains powerful antioxidants to repair and reverse existing sun damage. (4.2 oz)
