Ingredient review
Fermented Spathularia Extract
INCI: Sodium Dacryopinax Spathularia/Glucose Ferment Extract
A gentle, fermented fungus extract that may help calm skin and provide light hydration, though research is still limited.
In plain English
This ingredient is made by fermenting a type of jelly fungus (Dacryopinax spathularia) with glucose, a simple sugar. The fermentation process creates compounds that can help soothe irritated skin and hold moisture. It's a newer, biotech-derived ingredient that's generally considered safe and gentle, but there isn't a lot of independent research on it yet.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A fermented extract derived from the jelly fungus Dacryopinax spathularia combined with glucose. It is produced through a controlled fermentation process, resulting in a mixture of polysaccharides and other bioactive compounds.
How it works
The polysaccharides in this extract form a thin, moisturizing film on the skin's surface, which helps reduce water loss. It also appears to have anti-inflammatory properties, potentially calming redness and irritation by interacting with skin cells to reduce the production of inflammatory signals.
Pros
Gentle soothing
May help calm redness and irritation, making it suitable for sensitive skin routines.
Light hydration
Provides a subtle moisture boost without feeling heavy or sticky, ideal for layering.
Cons and cautions
Limited research
Most evidence comes from the manufacturer; independent studies are scarce, so benefits are not fully confirmed.
Newer ingredient
Less widely tested in long-term use compared to classic humectants like glycerin or hyaluronic acid.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, hydrating ingredient in serums or moisturizers
Use caution if
- Anyone with a known allergy to fungi or fermented ingredients (very rare)
Usage tips
Safety summary
Considered safe for topical use with a low risk of irritation. As with any new ingredient, patch testing is recommended for those with very sensitive skin or allergies to fungi.
Research notes
Preliminary studies suggest anti-inflammatory and moisturizing properties, but peer-reviewed human trials are lacking. Most data comes from cosmetic ingredient suppliers.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for cosmetic use in most regions including the EU and US, with no specific restrictions.
