Science
Mechanism of Action
This extract operates through a complex blend of active components, including gallotannins, tannins, phenolic compounds, free gallic acid, and methyl gallate. It exhibits significant antioxidant effects by neutralizing reactive oxygen species (ROS) and protecting keratinocytes from cytotoxicity, thereby inhibiting apoptosis and cell cycle alterations. Its anti-inflammatory action stems from its ability to inhibit human mast cells, reducing irritation and allergic reactions due to fisetin and pentagalloylglucose. Furthermore, it shows promise in promoting skin moisturization and reducing wrinkle appearance by inhibiting the elastase enzyme and potentially supporting collagen synthesis, making it a comprehensive ingredient for cellular protection and rejuvenation.

Efficacious concentrations appear to be relatively low.
