Science
Mechanism of Action
This extract operates through a complex blend of bioactive compounds. Flavonoids function as potent free radical scavengers, aiding in the protection against oxidative stress and mitigating signs of premature skin aging. Tannins impart an astringent effect by interacting with surface proteins, which can lead to a reduction in pore appearance and a smoother skin texture. Mucilages are responsible for its hydrating and calming effects, while volatile oils contribute to its antibacterial action. Additionally, the extract demonstrates anti-inflammatory properties, promoting overall skin comfort.

For optimal stability, it is recommended to incorporate the extract into the water phase of formulations. Products should be stored in closed containers, away from direct heat and sunlight. Shaking the product before application is advised to ensure even distribution of components.
