What Is Phellinus Linteus/Nelumbo Nucifera Leaf/Sea Water Ferment Extract Filtrate?
Phellinus Linteus/Nelumbo Nucifera Leaf/Sea Water Ferment Extract Filtrate comes from a three-part blend: lotus leaves, mineral-rich sea water and the fungus Phellinus linteus (now officially called Tropicoporus linteus). Producers steep lotus leaves in sea water, then let the fungus ferment the mixture. After the fermentation finishes, the liquid is filtered to remove solids, leaving a clear filtrate packed with skin-friendly compounds.
The filtrate carries polyphenols and flavonoids from the lotus leaf, beta-glucans from the fungus and trace minerals from sea water. These natural molecules are known for supporting the skin’s own defense system and helping it stay hydrated.
Fermented botanical ingredients rose to fame in Korean beauty labs during the early 2000s when formulators noticed that microbes break large plant molecules into smaller ones that the skin can absorb more easily. Since then, this particular filtrate has found its way into moisturizers, anti-aging serums, soothing sheet masks and after-sun gels.
The making process is straightforward but time-intensive. Clean lotus leaves soak in sterilized sea water. A controlled amount of Phellinus linteus is added and the tank is kept at a warm, steady temperature. Over several days the fungus digests plant sugars, creating new bioactive metabolites. Once testing confirms the right level of activity, the brew is filtered and preserved for cosmetic use.
Phellinus Linteus/Nelumbo Nucifera Leaf/Sea Water Ferment Extract Filtrate’s Cosmetic Benefits/Uses
This multitasking ferment supports the skin in two main ways
- Antioxidant: The polyphenols and beta-glucans help neutralize free radicals produced by UV light and pollution. Formulators add the filtrate to limit oxidative stress which can show up as dull tone fine lines and a rough surface
- Humectant: Natural sugars pull water from the environment and bind it to the outer skin layers. This boosts moisture levels keeps skin feeling soft and can enhance the spreadability of creams and gels
Who Can Use Phellinus Linteus/Nelumbo Nucifera Leaf/Sea Water Ferment Extract Filtrate
This ferment is lightweight and water based so it suits most skin types. Dry and mature skin appreciate the extra humectant boost while sensitive complexions often like its calming beta glucans. Oily or combination skin can also benefit because the filtrate adds hydration without heavy oils. There is no known reason normal skin types could not use it.
The ingredient is vegan friendly since it comes only from lotus leaves, sea water and a cultivated fungus. No animal products or by-products are involved in either the culture medium or the extraction process so vegetarians and vegans can use it with confidence.
Pregnant or breastfeeding women are not known to face specific risks with this ferment. It does not contain vitamin A derivatives, salicylic acid or other actives that commonly raise concern during pregnancy. Still this is not medical advice and anyone who is expecting or nursing should show the full product label to their doctor before adding it to a routine.
The filtrate does not make skin more sensitive to sunlight. It can even provide mild antioxidant support against UV stress but it is no substitute for sunscreen which should remain a daily habit.
Potential Side Effects/Adverse Reactions
Individual responses to topical Phellinus Linteus/Nelumbo Nucifera Leaf/Sea Water Ferment Extract Filtrate vary. The points below cover potential issues that have been observed or could theoretically occur. They remain uncommon for most users when the ingredient is properly formulated and preserved.
- Temporary redness or stinging on very reactive skin
- Allergic contact dermatitis in people sensitive to mushroom or lotus extracts
- Breakouts in those highly prone to fungal acne though evidence is limited
- Irritation if layered with strong exfoliating acids or retinoids without adequate spacing
- Contamination-related irritation if the finished product is not well preserved
If any burning itching swelling or rash develops stop using the product immediately and seek advice from a qualified healthcare professional.
Comedogenic Rating
Rating: 0 / 5 (non-comedogenic)
The filtrate is water based and contains almost no fatty acids or heavy oils that could clog pores. Its main components are small sugars, polyphenols and minerals that dissolve fully in water and rinse away easily. Because it sits light on the skin and does not form an occlusive film, the chance of it blocking follicles is extremely low.
Is it suitable for acne-prone skin? Yes, most people prone to breakouts can use it without fear of worsening congestion.
Extra note: products that combine this ferment with thick butters or poorly preserved formulas could still trigger pimples, so check the whole ingredient list rather than judging on this ferment alone.
Summary
Phellinus Linteus/Nelumbo Nucifera Leaf/Sea Water Ferment Extract Filtrate delivers two headline benefits: antioxidant support and long-lasting hydration. Fermentation unlocks smaller, more skin-ready molecules from lotus leaves and the fungus adds soothing beta glucans, while sea water supplies trace minerals. Together they help neutralize free radicals and bind water to the skin’s surface for a plumper look.
Although not a household name, the ferment has carved out a quiet following in K-beauty style essences, lightweight gels and after-sun sprays where users want a gentle plant-derived boost without heaviness.
Overall safety is high, with low irritation and zero comedogenicity for most users. Still, every skin is different so do a quick patch test whenever you bring a new product containing this ingredient into your routine.
