What does Green Tea Extract do?#
An antioxidant-rich serum with green tea extract (EGCG) that provides antioxidant support for a calmer, more even-looking complexion that looks healthy despite everyday environmental stress.
- Provides antioxidant support for a healthier, more radiant-looking complexion
- Supports a calmer, less red-looking complexion
- Helps skin look less shiny, for a more balanced-looking complexion
- Lightweight serum absorbs easily
How it works
Green tea extract is rich in EGCG, a powerful plant-based antioxidant. It provides antioxidant support for skin that looks healthy and radiant despite everyday environmental stress while supporting a calmer, more balanced-looking complexion. Its natural antioxidant properties help maintain a healthier, more vibrant skin appearance.
How to use Green Tea Extract#
- Daily from the first day, and twice a day if you like — that is how it has been used in every study of it, and there is no need to build up.
- Morning or evening both suit it. Every study of it applied it twice a day, and nothing in them favours one time over the other.
- Across the whole face rather than dabbed on individual marks — every study of it applied it to the whole area.
- Keep it away from your eyes, and rinse with water if any gets in.
- Expect nothing dramatic in the first weeks. There is no purge and no settling-in period with this one — it is a steady, gradual ingredient.
- Patch test first if you react easily to plant extracts. Reactions are rare, but this is a botanical.
- Store it somewhere cool and dark. Light is hard on it, which is why the bottle is usually opaque.
Discontinue use if unexpected discomfort occurs.

Some sources below are the official product information for prescription medicines — some contain this ingredient at higher strengths, others are cited for how they interact with it. We use them for their safety and handling detail only. A cosmetic product is not one of those medicines and is not intended to treat any condition.
