Formulation view Core physical filters include zinc oxide and titanium dioxide, balanced with light coconut alkanes and volatile esters for improved spreadability. Hygroscopic polymers prevent clumping, while squalane provides moisture. Suitable for immediate, lightweight sun protection, with factory focus on oil-phase dispersion technology to ensure even filter coverage.E · AI inference · to be verified
