What Is Camellia Sinensis Leaf?
Camellia sinensis leaf is an extract derived from the tea plant, commonly known as green tea. It contains polyphenols and other naturally occurring compounds that function as antioxidants and skin-conditioning agents in cosmetic formulations.
In skincare products, this ingredient is typically used to help protect the skin and maintain its condition, rather than to deliver therapeutic effects. The properties of the extract can vary depending on how it is processed and manufactured.
Benefits for Your Skin
How It Works
Camellia sinensis leaf contains polyphenols, which are naturally occurring compounds with antioxidant properties. These work by neutralising free radicals—unstable molecules that can contribute to skin damage and ageing.
The extract also functions as a humectant and general skin-conditioning agent, helping to support skin barrier function and hydration. The exact mechanisms may vary depending on the concentration and formulation of the extract used.
Clinical Evidence & References
Research supports the use of green tea extracts in cosmetics, with evidence for antioxidant and skin-conditioning benefits. A small randomised trial found that a combination formula containing camellia sinensis leaf extract alongside other botanical ingredients showed improvements in acne lesions and skin appearance when compared to baseline, though this was part of a multi-ingredient product so individual contribution is unclear.
The evidence base is most robust for antioxidant activity. Safety data from cosmetic and beverage use suggests the ingredient is well-tolerated at typical cosmetic concentrations. However, because formulations often contain multiple botanical ingredients with overlapping constituents, formulators are advised to monitor total concentrations to avoid potential sensitisation.

How to Use
Camellia sinensis leaf is typically found in serums, toners, and moisturisers at very low concentrations (generally under 1%). It can be used daily as part of a regular skincare routine. Because it is usually present in small amounts, it works best as part of a broader skincare regimen rather than as a standalone treatment for specific concerns.
