2-Phenylbenzimidazole-5-sulfonic acid (PBSA) and disodium phenyl dibenzimidazole tetrasulfonate (DPDT) are commercially available ultraviolet (UV) sunscreen filters that known to undergo radiative relaxation following the absorption of UV light. The release high-energy photons from this can be detrimental human health; therefore, fluorescence quenchers need incorporated in commercial formulations containing PBSA or DPDT. Troxerutin is a quencher utilized for DPDT commercially. Here, its ability quench both evaluated using dual-pronged approach by breaking down multicomponent problem into constituent parts. First, DPDT's femtosecond nanosecond photodynamics uncovered solution on surface skin mimic ascertain benchmark. Second, these results compared their presence troxerutin. A significant reduction lifetime observed with addition troxerutin, which attributed Dexter energy transfer (DET) Förster resonance (FRET) quenching mechanism. This finding demonstrates hitherto unseen mechanism troxerutin role through DET FRET
