What Is Green Tea Extract?
Green tea extract is derived from the leaves of Camellia sinensis and is one of the most researched botanical antioxidants in skincare. Its key active compound is epigallocatechin gallate (EGCG), a potent polyphenol with exceptional protective properties.
EGCG and other catechins in green tea provide powerful antioxidant protection, neutralizing free radicals caused by UV exposure and environmental pollution. Research has shown green tea extract can help prevent collagen breakdown and reduce signs of photoageing.
Green tea extract also has anti-inflammatory and antimicrobial properties, making it beneficial for acne-prone and sensitive skin. It can help reduce redness, calm irritation, and regulate sebum production.
For maximum benefit, look for products with green tea extract listed high in the ingredient list, ideally in concentrations of 1-5%. It works well in combination with other antioxidants like vitamins C and E.
Clinical Evidence & References
Green tea extract has substantial clinical support underpinning its use in skincare. The ingredient's primary active compound, epigallocatechin gallate (EGCG), is a polyphenol with well-documented antioxidant capacity. Published research demonstrates that green tea extract neutralises free radicals from UV exposure and environmental stress, helping to prevent collagen degradation and reduce photoageing markers. Additionally, its anti-inflammatory and antimicrobial properties have shown benefit in managing acne-prone and sensitive skin through redness reduction and sebum regulation.
Whilst the evidence base is robust, individual response varies. Most studies assess topical application over 4–12 weeks, so clinical improvements develop gradually rather than immediately. Concentration and formulation quality influence efficacy; higher positioning in ingredient lists generally correlates with more meaningful effect. The ingredient remains well-tolerated across skin types, though those with known sensitivity to botanicals should patch-test first.
