What Is Lepisorus Thunbergianus Extract?
Lepisorus Thunbergianus Extract comes from the whole Lepisorus thunbergianus plant, a small evergreen fern in the Polypodiaceae family that grows in the moist woodlands of East Asia. The fronds contain helpful compounds such as flavonoids, phenolic acids and natural sugars that are prized for their soothing and moisturizing traits. In folk beauty practices throughout Japan and Korea the fern was steeped in water and the liquid was used to calm rough skin. Modern manufacturers pick the plant, wash and dry it, then grind it into a powder. The powder is soaked in water or a gentle food grade solvent to pull out the active molecules, after which the liquid is filtered and concentrated into a clear or lightly tinted extract that blends easily into creams and gels. You will often spot it in hydrating sheet masks, anti aging serums, daily moisturizers, after sun gels and sensitive skin treatments.
Lepisorus Thunbergianus Extract’s Cosmetic Benefits/Uses
This fern extract serves a single yet valuable role in skincare: skin conditioning. By binding water to the surface of the skin and laying down a thin breathable film it helps keep the complexion soft, smooth and comfortably hydrated. Its natural antioxidants also support a healthy looking barrier which may reduce the appearance of dullness or stress over time.
Who Can Use Lepisorus Thunbergianus Extract?
This botanical is gentle enough for all skin types. Dry or mature complexions appreciate its water-binding effect while sensitive skin benefits from its calming plant antioxidants. The extract is lightweight and non-pore-clogging so combination and oily skin can also use it without fear of extra shine or breakouts.
Because the ingredient is derived entirely from a plant and no animal-based processing aids are typically involved, it is suitable for both vegans and vegetarians.

Comedogenic Rating
Rating: 1/5. Lepisorus Thunbergianus Extract is mostly water soluble and contains lightweight humectants rather than rich oils or waxes that can clog pores. It creates only a thin breathable film on the surface, so the chance of trapping sebum and debris is very low. This makes the extract well suited for people who are prone to acne or breakouts. As with any ingredient the overall formula matters, meaning a product packed with heavy butters could still feel greasy even if this fern extract itself is not.
Summary
Lepisorus Thunbergianus Extract is used in skincare for one key reason: it conditions the skin. The sugars and phenolic antioxidants in the fern draw water into the outer layer and help maintain a smooth, calm barrier, giving the complexion a softer and fresher look. While not as famous as hyaluronic acid or aloe, it shows up in a growing number of moisturizers, serums and sheet masks aimed at soothing and hydrating without heaviness.
Current data and on-market experience suggest the ingredient is safe for general use with only rare reports of mild irritation or allergy. Still, every skin is different, so perform a quick patch test when trying any new product that contains this extract to ensure it agrees with you.
