What Is Cyathea Medullaris Leaf Extract?
Cyathea medullaris leaf extract comes from the ponga, a native New Zealand tree fern. The extract is obtained from the plant's fronds and functions primarily as a skin conditioner in formulations.
In skincare products, this ingredient is used to help maintain skin's texture and moisture balance, though it is relatively uncommon in mainstream formulations.
How It Works
As a skin conditioner, Cyathea medullaris leaf extract is thought to work by forming a lightweight protective layer on the skin's surface, which can help reduce transepidermal water loss and maintain hydration.
The exact mechanisms of action are not extensively documented in peer-reviewed literature, and the ingredient's efficacy likely depends on the extraction method and formulation context.
Clinical Evidence & References
Published clinical data on Cyathea medullaris leaf extract is limited. Most evidence for its benefits comes from traditional use and in vitro studies rather than rigorous human trials.
While plant-derived extracts can offer skin-conditioning benefits, more robust clinical research would be needed to establish specific claims about efficacy in skincare products containing this ingredient.
How to Use
This ingredient is typically used as a supporting ingredient in serums, moisturisers and other hydrating formulations rather than a primary active. Apply products containing this extract to clean skin as directed, and use consistently to allow conditioning benefits to become apparent over time.
