Science
Mechanism of Action
Functions as a highly polar solvent that optimizes energy transfer between UV filters, preventing their breakdown under sun exposure through photostabilization. Simultaneously improves the wetting and dispersion of inorganic UV blockers like zinc oxide and titanium dioxide, while providing mild chemical UV absorption similar to octisalate.
