Ingredient review
Fermented Mulberry Wood Extract
INCI: Phellinus Linteus/Morus Bombycis Wood Powder Ferment Extract
A fermented botanical extract that may help calm skin and fight free radicals, but research is still early.
In plain English
This ingredient is made by fermenting a type of medicinal mushroom (Phellinus linteus) with mulberry wood powder. Fermentation breaks down the plant materials into smaller, potentially more absorbable compounds. In skincare, it's used to provide antioxidant protection and soothe the skin, though most evidence comes from lab studies rather than human trials.

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 fermented extract combining Phellinus linteus (a mushroom used in traditional medicine) and Morus bombycis (mulberry wood). The fermentation process is believed to enhance the bioavailability of active compounds like polyphenols and polysaccharides.
How it works
The fermentation process creates smaller molecules that may penetrate the skin more easily. The resulting compounds act as antioxidants, neutralizing free radicals that can damage skin cells. Some components may also help reduce inflammation and support the skin's natural barrier function.
Pros
Gentle antioxidant
Provides antioxidant benefits without common irritation, making it suitable for sensitive skin types.
Fermentation benefits
The fermentation process may make active compounds more bioavailable, potentially increasing their effectiveness on the skin.
Cons and cautions
Limited research
Most studies are lab-based or traditional medicine focused; there are few rigorous human trials on topical use in cosmetics.
Uncommon ingredient
Not widely studied or used in mainstream Western skincare, so long-term safety data is sparse.
Best for
- Those interested in fermented skincare ingredients
- People looking for antioxidant protection with a gentle profile
Use caution if
- Anyone with known allergies to mushrooms or mulberry
- Those with very sensitive skin who react to fermented ingredients
Usage tips
Safety summary
Considered safe for topical use in cosmetics at typical concentrations. The fermentation process reduces the risk of contamination and may improve tolerability. However, as with any botanical, individual allergic reactions are possible.
Research notes
Research on Phellinus linteus and Morus bombycis is primarily in the context of traditional medicine and in vitro studies. There is emerging interest in their cosmetic applications, but more human clinical trials are needed to confirm benefits.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used at typical concentrations.
- Common uses
- Serums, Moisturizers, Essences
- Environmental note
- Mulberry wood is a renewable resource, and fermentation is a low-energy processing method, making this ingredient relatively sustainable.
Good to know
- Phellinus linteus is also known as sanghwang mushroom in Korean traditional medicine.
- Fermented ingredients are often more stable and have a longer shelf life than their raw plant counterparts.
