Science
Mechanism of Action
This peptide functions by establishing a structured protective matrix on the stratum corneum. This barrier intercepts exogenous aggressors, such as particulate pollution and UV-induced oxidative stress, while simultaneously preventing moisture evaporation to maintain cellular hydration and softness.
