Invisible defense. This lightweight, broad-spectrum physical barrier is your first line of defense against sun damage and premature skin aging. Formulated with naturally occurring titanium dioxide, Liquid Layer provides water-resistant SPF30 protection against UVA, UVB rays and pollution. Polymeric spheres diffuse and redirect UV light, preventing harsh, multiple assaults from the environment. Cellular-protecting antioxidants and photoprotectants help to defend against daily pollutants, which can accelerate irreversible free-radical damage.
