Science
Mechanism of Action
This extract functions primarily as a humectant, effectively drawing and retaining crucial moisture in the skin, alongside acting as an emollient to impart a softer, smoother texture. Its potent antioxidant mechanism involves the direct scavenging of DPPH and ABTS radicals, coupled with a notable reduction in intracellular reactive oxygen species (ROS) in skin cells. Furthermore, Diphylleia Grayi Extract inhibits key enzymes: tyrosinase and L-DOPA oxidation for melanin pathway modulation, and collagenase for maintaining collagen integrity and skin firmness.
