This water-in-oil sunscreen cream provides broad spectrum sun protection without using organic UV filters. The amazing, photostabilizing, anti-aging ingredient, SolaStay® S1, mitigates the photocatalytic and reactive oxygen species-generating activities of the oxides. The addition of dermollient Sensolene® adds a unique sensoriality.
This formula was subjected to in vitro analysis and delivered SPF ~60, PFA (PPD) ~14 performance with critical wavelength 373 nm.
