Science
Mechanism of Action
This multi-functional powder utilizes high-catechin green tea leaves to neutralize oxidative stress and absorb excess lipids. Simultaneously, the iron hydroxide component acts as a physical light-reflector, scattering light to visually diminish the depth of fine lines and providing natural, earthy pigmentation.
