Polyphenols and Antioxidant Kinetics in Matcha Skincare
Matcha Skincare utilizes the powdered leaves of Camellia sinensis as a bioactive ingredient. The technical value of Matcha lies in its high concentration of Epigallocatechin Gallate (EGCG), a potent polyphenol.
In topical formulations, EGCG acts as an antioxidant that neutralizes reactive oxygen species (ROS) caused by UV exposure. The production process involves "Shade-Grown" cultivation, which increases the chlorophyll and L-theanine content. To maintain the stability of these volatile compounds, the skincare product must be formulated at a specific pH (typically between 4.0 and 6.0) and stored in opaque, airless packaging to prevent "Photo-oxidation."
