What Is Polypodium Polypodioides Extract?

Polypodium polypodioides extract is derived from the resurrection fern, a plant known for its ability to survive extreme dehydration and recover when moisture returns. In skincare formulations, this extract functions as a skin conditioning agent.

The extract contains compounds that may help maintain skin hydration and support the skin barrier. It is typically incorporated into moisturisers, serums and protective products at relatively modest concentrations.

How It Works

The fern extract's conditioning properties are thought to stem from its polysaccharide and amino acid content. These compounds can form a light protective layer on the skin and help reduce transepidermal water loss, allowing the skin to feel and appear more hydrated.

The extract's natural antioxidants may also help neutralise free radicals generated by UV exposure and environmental pollution, although more research is needed to quantify this benefit in cosmetic applications.

Clinical Evidence & References

Published research on polypodium polypodioides extract in skincare is limited. Most evidence comes from in vitro and animal studies, which suggest the extract has hydrating and antioxidant properties, but human clinical trials confirming efficacy in cosmetic formulations are sparse.

The ingredient is well-established in traditional herbalism and appears safe for topical use, but claims should be treated with appropriate caution until further human studies are available. It is most credible when positioned as a general skin conditioner rather than a targeted treatment.

How to Use

This ingredient works best in formulations designed to hydrate and protect, such as moisturisers and serums. It can be used daily as part of a routine and pairs well with other hydrating and antioxidant ingredients. As with any skincare product, patch testing is advisable if you have known sensitivities.

Safety & Precautions

Polypodium polypodioides extract is generally well-tolerated and has a low sensitisation risk. No major safety concerns are documented, though individuals with fern allergies should avoid products containing this ingredient.
