What Is Hydrolyzed Camellia Sinensis Leaf Extract?

Hydrolyzed Camellia sinensis leaf extract is derived from green tea leaves that have been broken down into smaller molecular components through hydrolysis. This processing method increases the bioavailability of the active compounds naturally present in green tea, such as catechins and polyphenols, making them more readily absorbed by the skin.

In skincare formulations, this ingredient functions primarily as an antioxidant and skin conditioning agent. It helps protect the skin from environmental stressors and supports the skin's natural defences.

Benefits for Your Skin

How It Works

The hydrolyzed form breaks down the tea leaf components into smaller molecules, allowing them to penetrate the skin more effectively than whole leaf extract. Once absorbed, the active polyphenols work as antioxidants by donating electrons to free radicals, thereby neutralising them and reducing oxidative stress within the skin.

The ingredient's antiseborrhoeic (oil-reducing) properties are thought to stem from these same polyphenolic compounds, which may help regulate sebaceous gland activity and reduce excess oil production on the skin's surface.

Clinical Evidence & References

Green tea extract and its derivatives have been studied in skincare research, with some evidence suggesting benefits for oily skin and antioxidant protection. However, the specific clinical data on hydrolyzed Camellia sinensis leaf extract in isolation is limited, and most supporting evidence comes from broader studies on green tea compounds rather than this processed form specifically.

The ingredient is recognised as a safe and effective antioxidant in cosmetic formulations, though individual results may vary depending on concentration and formulation context.

How to Use

This ingredient works well in serums, essences, toners and moisturisers. It is stable in most formulations and does not typically require special pH adjustments. Apply as part of your regular skincare routine; benefits tend to build over consistent use rather than appearing immediately.

Safety & Precautions

Hydrolyzed Camellia sinensis leaf extract is generally well-tolerated across most skin types. Those with known sensitivity to green tea or botanical extracts should patch test first, though allergic reactions are uncommon.
