Matsutake Mushroom Ferment Filtrate
INCI: Tricholoma Matsutake Ferment Filtrate
A gentle, antioxidant-rich mushroom ferment that may help calm skin and defend against environmental stress.
In plain English
This ingredient is a liquid made by fermenting matsutake mushrooms, a rare and aromatic fungus. The fermentation process breaks down the mushroom's compounds, making them easier for skin to absorb. It's thought to provide antioxidant protection (helping fight damage from pollution and UV) and may soothe irritation. Think of it as a gentle, natural skin tonic that supports your skin's defenses.

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

emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A fermented filtrate from the Tricholoma matsutake mushroom, also known as pine mushroom. The mushroom is fermented with beneficial microbes, then filtered to create a liquid rich in peptides, polysaccharides, and antioxidants.
How it works
The fermentation process creates smaller, more bioavailable molecules that can penetrate the skin's surface. These compounds may help neutralize free radicals, reduce oxidative stress, and support the skin's natural barrier function. The polysaccharides can also provide a mild film-forming effect, helping to retain moisture.
Pros
Gentle antioxidant support
Helps protect skin from daily environmental damage without irritation, making it suitable for sensitive skin types.
Soothing potential
Early research suggests it may calm inflammation and redness, which is helpful for reactive or stressed skin.
Cons and cautions
Limited scientific backing
Most evidence comes from lab studies or traditional use; large-scale human trials are lacking, so benefits are not fully proven.
Higher cost and rarity
Matsutake mushrooms are difficult to cultivate and harvest, which can make products containing this ingredient more expensive.
Best for
- Anyone looking for a gentle antioxidant boost
- People with sensitive or reactive skin seeking soothing ingredients
Use caution if
- Individuals with a known allergy to mushrooms or molds
Usage tips
Safety summary
