Ingredient review
Phellinus Linteus & Abalone Ferment
INCI: Phellinus Linteus/Abalone Ferment Filtrate
A fermented mushroom and abalone extract that may offer antioxidant and soothing benefits, but research is limited.
In plain English
This ingredient is made by fermenting a medicinal mushroom called Phellinus linteus with abalone. Fermentation breaks down the raw materials into smaller, potentially more absorbable compounds. In skincare, it's thought to help protect the skin from environmental stress and calm irritation, though most evidence comes from traditional use and lab studies rather than large human trials.

Quick decision guide
Useful, but context matters
Phellinus Linteus & Abalone Ferment is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Phellinus Linteus & Abalone Ferment.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A filtrate obtained after fermenting Phellinus linteus (a type of mushroom used in traditional medicine) with abalone (a marine mollusk). The fermentation process creates a liquid rich in amino acids, peptides, and polysaccharides.
How it works
The fermentation process releases bioactive compounds that may act as antioxidants, helping to neutralize free radicals that can damage skin cells. The peptides and amino acids can also support skin hydration and barrier function by attracting moisture and providing building blocks for skin repair.
Pros
Antioxidant potential
The mushroom component is rich in polysaccharides and phenolics that may help protect skin from oxidative stress caused by pollution and UV exposure.
Soothing properties
Traditional use of Phellinus linteus suggests anti-inflammatory effects, which could translate to calmer, less reactive skin.
Cons and cautions
Limited research
Most evidence is from lab or traditional use, not large-scale human trials. The specific benefits in skincare are not well-documented.
Allergen risk
Since abalone is a shellfish, this ingredient may trigger allergic reactions in people with shellfish sensitivities, though the risk is low due to processing.
Best for
- Those interested in fermented skincare ingredients
- People looking for antioxidant-rich products
Use caution if
- Individuals with shellfish allergies (abalone is a mollusk)
- Those who prefer ingredients with more clinical backing
Usage tips
Safety summary
Considered safe for topical use with low irritation potential. The main concern is allergic reaction in shellfish-sensitive individuals, though the risk is minimal due to the fermentation and filtration process.
Research notes
Research on Phellinus linteus shows antioxidant and anti-inflammatory activity in lab studies. The combination with abalone is novel and lacks direct clinical evidence in skincare.
Common label clues
- Typical concentration
- Typically used at 1-5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU, but not specifically regulated as a drug ingredient.
- Common uses
- Serums, Essences, Moisturizers
- Environmental note
- Abalone farming can have environmental impacts, but fermentation uses byproducts or small amounts, reducing waste.
Good to know
- Fermentation often increases the bioavailability of active compounds
- This ingredient is more common in K-beauty and J-beauty products
