Science
Mechanism of Action
Functions through high concentrations of verbascoside and isoverbascoside, which neutralize UV-induced reactive oxygen species, suppress pro-inflammatory IL-8 expression, and inhibit matrix-degrading enzymes including MMPs, collagenase, elastase, and hyaluronidase while blocking tyrosinase activity for pigmentation control.
