What it does
A potent antioxidant from green tea leaves. Neutralizes free radicals from UV and pollution, supports collagen, and calms inflammation.
Best for
Daytime use (antioxidant defense), aging skin, and anyone in a high-pollution environment.
The full picture
Green tea extract delivers EGCG (epigallocatechin gallate) and related catechins, a class of antioxidants that are particularly effective against UV-induced free radicals. The extract has well-documented anti-inflammatory effects and supports collagen integrity over time. It is a common supporting ingredient in modern lifting creams (including OKOA Dual Action) where it complements peptide-driven structural support with antioxidant defense.
Evidence
Topical green tea polyphenols reduce UV-induced damage and inflammation in skin.
