Ingredient review
Polypodium Polypodioides Extract
INCI: Polypodium Polypodioides Extract
A fern-derived antioxidant that may help shield skin from UV-related damage and support a more even complexion, but human skincare studies are still limited.
In plain English
Polypodium polypodioides extract comes from a tropical fern that can survive extreme dryness. In skincare, it's valued for its antioxidant properties, meaning it can help neutralize unstable molecules called free radicals that are generated by UV rays and pollution. This may help reduce visible signs of aging and uneven pigmentation. Think of it as a plant-powered shield for your skin, though it's not a replacement for sunscreen.

What it is
A natural extract from the leaves of the Polypodium polypodioides fern, also known as resurrection fern or calaguala. It contains a mix of polyphenols, flavonoids, and other antioxidant compounds.
How it works
The extract's antioxidant compounds scavenge free radicals before they can damage skin cells and break down collagen. It also appears to calm certain inflammatory pathways in the skin, which can help reduce redness and support a more even skin tone over time.
Pros
Antioxidant protection
Helps neutralize free radicals from UV and pollution, which can reduce premature aging and support a healthier-looking complexion.
Gentle on skin
Low irritation and comedogenic risk makes it suitable for most skin types, including sensitive and acne-prone skin.
Cons and cautions
Limited human studies
Most research is on oral supplements or lab models; fewer rigorous studies confirm benefits when applied to skin in a cream or serum.
Variable potency
The concentration of active compounds can differ between brands and batches, so results may not be consistent from product to product.
Best for
- Anyone looking for extra antioxidant protection in their daytime routine
- People with sun-damaged or uneven skin tone seeking a gentle brightening aid
Use caution if
- Those with known allergy to ferns or related plants (rare)
Usage tips
Safety summary
Polypodium polypodioides extract is considered safe for topical use with a low risk of irritation or allergic reaction. As with any plant extract, patch test before first use if you have sensitive skin or a history of plant allergies.
Research notes
Oral Polypodium leucotomos extract has moderate evidence for reducing sunburn and supporting skin repair. Topical studies are fewer but suggest antioxidant and anti-inflammatory benefits. More human trials are needed to confirm efficacy in leave-on skincare.
Common label clues
