Overview
Rich in polyphenols, especially EGCG, green tea is studied for antioxidant and soothing effects both consumed and applied.
What it is
Green tea leaves are minimally oxidized, preserving catechins such as epigallocatechin gallate (EGCG). It has a long history in East Asian daily ritual and is now one of the most researched botanicals in dermatology.
In skincare it appears in toners, serums, and mists, often marketed for calming and oil control.
How it works
- Catechins scavenge free radicals and have been studied for reducing UV-related oxidative stress.
- EGCG has shown anti-inflammatory activity in laboratory and some clinical studies.
- May modestly influence sebum production, according to small studies.
Potential benefits
- Antioxidant support
- Soothing effect for redness-prone skin
- Refreshing, lightweight hydration
