Ingredient review
Fermented Schisandra & Polygonatum Complex
INCI: AUREOBASIDIUM PULLULANS/SCHISANDRA CHINENSIS FRUIT/POLYGONATUM SIBIRICUM RHIZOME/ROOT EXTRACT FERMENT FILTRATE
A fermented botanical extract that may help calm and protect skin, though human studies are limited.
In plain English
This ingredient is made by fermenting two traditional herbal extracts—schisandra fruit and Siberian Solomon's seal root—with a friendly yeast called Aureobasidium pullulans. Fermentation can break down plant compounds into smaller, potentially more absorbable pieces, and may boost antioxidant and soothing effects. It's used in skincare to help defend against environmental stress and support a balanced, comfortable complexion.
Quick decision guide
Useful, but context matters
Fermented Schisandra & Polygonatum Complex is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Fermented Schisandra & Polygonatum Complex.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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 filtrate derived from the yeast Aureobasidium pullulans acting on schisandra fruit and Polygonatum sibiricum (Siberian Solomon's seal) rhizome/root. The fermentation process is intended to generate bioactive peptides and polyphenols.
How it works
During fermentation, the yeast metabolizes plant sugars and compounds, producing a filtrate rich in amino acids, peptides, and antioxidant molecules. When applied to skin, these components may help neutralize free radicals, support the skin's natural barrier, and reduce signs of irritation.
Pros
Gentle antioxidant support
The fermentation process may create smaller, more skin-friendly molecules that help defend against daily pollution and UV stress without irritation.
Potential soothing effect
Traditional use of schisandra and Polygonatum suggests anti-inflammatory properties, which may translate to a calming effect on redness or sensitivity.
Cons and cautions
Limited human research
Most evidence comes from lab or traditional use; there are few peer-reviewed human studies on this exact fermented blend, so effectiveness is not fully proven.
Possible allergen risk
As a complex botanical ferment, individuals with plant or yeast allergies may experience a reaction; patch testing is recommended.
Best for
- Anyone looking for antioxidant support in a gentle, fermented format
- Those with normal to dry skin seeking extra soothing ingredients
Use caution if
- Individuals with known allergies to any of the source plants (schisandra, Polygonatum) or yeast
Usage tips
Safety summary
This fermented botanical blend is considered low-risk for most skin types. The yeast and plant sources have a history of safe use in cosmetics. As with any new ingredient, patch testing is advised, especially for those with sensitive skin or plant allergies.
Research notes
Evidence is primarily based on traditional use and in vitro studies showing antioxidant and anti-inflammatory activity. Human clinical trials on this specific ferment are lacking, but related fermented ingredients (e.g., galactomyces) have demonstrated skin barrier benefits.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on formulas
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used as a cosmetic ingredient. Not approved as a drug.
- Common uses
- Serums, Moisturizers, Toning essences
- Environmental note
- The fermentation process is relatively low-energy and can utilize renewable plant biomass, making it a more sustainable sourcing method compared to wild-harvesting.
Good to know
- Aureobasidium pullulans is a common yeast used in biotechnology and is generally recognized as safe for topical use.
- Schisandra chinensis is known in traditional Chinese medicine as a 'five-flavor berry' and is rich in lignans with antioxidant activity.
