A broad spectrum sunscreen cream. This formula is suitable for beachwear or any outdoor activity and provides superior broad-spectrum protection against both the burning and aging rays of the sun. SolaStay® S1, an extremely rapid singlet state quenching photostabilizer, and triple state quenching Polycrylene® help keep the formulation from losing effectiveness during sun exposure. In vitro analysis suggests SPF ~55, PFA (PPD) ~21 performance with critical wavelength 380 nm.
