Science

Mechanism of Action

This extract operates via a dual-action pathway: it neutralizes reactive oxygen species (ROS) through phyto-actives like catechins and amentoflavones, while simultaneously inhibiting matrix metalloproteinases (MMPs) and elastase enzymes to prevent the degradation of collagen and elastin. Its hydrophilic structure further enables it to bind water molecules, enhancing moisture retention within the stratum corneum.
