Ingredient review
Maitake-Burdock Ferment Extract
INCI: Grifola Frondosa/Arctium Lappa Fruit Extract Ferment Filtrate
A fermented botanical blend that may help calm skin and fight free radicals, though research is still emerging.
In plain English
This ingredient is made by fermenting maitake mushroom and burdock fruit together. Fermentation can break down plant compounds into smaller pieces that skin may absorb more easily. It's thought to provide antioxidant benefits (helping protect skin from environmental damage) and soothing effects, but most evidence comes from traditional use and lab studies, not large human trials.

What it is
A fermented filtrate combining Grifola frondosa (maitake mushroom) and Arctium lappa (burdock) fruit extract. The fermentation process uses beneficial microbes to transform the plant material, potentially enhancing the bioavailability of active compounds.
How it works
In a cosmetic product, this ingredient is believed to deliver antioxidant compounds that neutralize free radicals, and may help calm irritated skin. The fermentation step may also produce additional beneficial metabolites like amino acids and enzymes that support skin health.
Pros
Gentle antioxidant
Provides a mild antioxidant effect that may help protect skin from daily environmental stressors without irritation.
Fermentation benefits
The fermentation process can create smaller, more skin-friendly molecules and add extra nutrients like amino acids.
Cons and cautions
Limited research
There are very few published studies on this exact fermented blend, so its benefits are mostly theoretical or based on traditional use.
Variable quality
The final ingredient's potency depends heavily on the fermentation method and raw material quality, which can differ between brands.
