Ingredient review
Fermented Snow Lotus Extract
INCI: Paecilomyces Japonica/Saussurea Involucrata Ferment Extract Filtrate
A gentle fermented botanical extract that may help soothe and protect skin, though human studies are limited.
In plain English
This ingredient is made by fermenting snow lotus (a rare mountain plant) with a type of fungus called Paecilomyces japonica. The fermentation process breaks down the plant material, potentially making its beneficial compounds easier for skin to absorb. It's used in skincare products mainly for its antioxidant and soothing effects, meaning it may help calm irritation and defend against environmental stress.

What it is
A fermented filtrate derived from the snow lotus plant (Saussurea involucrata) and the fungus Paecilomyces japonica. The fermentation process creates a liquid rich in peptides, polysaccharides, and other bioactive compounds.
How it works
The fermentation process produces smaller, more bioavailable molecules that can penetrate the skin more easily. These compounds are thought to have antioxidant properties, helping to neutralize free radicals that cause premature aging. They may also support the skin's natural barrier function and reduce signs of irritation.
Pros
Gentle antioxidant
Provides antioxidant protection without common irritants, making it suitable for sensitive skin types.
Soothing potential
Early research suggests it may help calm redness and irritation, offering a multi-functional benefit in one ingredient.
Cons and cautions
Limited human data
Most evidence comes from lab or animal studies; more human trials are needed to confirm benefits for everyday skincare.
Rare ingredient
Snow lotus is a protected plant in some regions, raising sustainability concerns about wild harvesting.
Best for
- People with dull or stressed skin looking for antioxidant support
- Those interested in fermented skincare ingredients for gentle exfoliation and barrier support
Use caution if
- Individuals with known allergies to snow lotus or Paecilomyces fungus
- Anyone with a compromised skin barrier should patch test first
