This natural (mineral UV filters only) broad spectrum sunscreen lotion uses SolaStay® S1 to mitigate the photocatalytic and reactive oxygen species generating activities of the oxides. It was subjected to in vitro analysis and delivered SPF ~54, PFA (PPD) ~18 performance with critical wavelength 378 nm. In vivo testing (three persons) yielded static SPF 57.9 in support of in vitro results.
