Ingredient review
Yeast Fermented Artichoke Tuber Extract
INCI: Saccharomyces/Hydrolyzed Stachys Affinis Tuber Ferment Extract
A gentle, fermented botanical extract that may help calm irritation and support skin hydration, though research is still early.
In plain English
This ingredient is made by fermenting a type of tuber (Chinese artichoke) with yeast. The fermentation process breaks down the plant material into smaller, potentially more skin-friendly compounds. It's used in skincare products to help soothe the skin and provide light hydration. Think of it as a gentle, plant-based ingredient that works with your skin's natural processes rather than forcing a change.

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

Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A fermented extract created by combining Saccharomyces (a type of yeast) with hydrolyzed tubers of Stachys affinis, also known as Chinese artichoke or Crosne. The fermentation process produces peptides, amino acids, and other bioactive compounds.
How it works
The fermentation process generates small peptides and sugars that can help support the skin's natural barrier function. These compounds may also have mild anti-inflammatory effects, helping to calm redness and irritation. The sugars provide light humectant (water-attracting) properties, helping the skin hold onto moisture.
Pros
Gentle on skin
The fermentation process breaks down plant compounds into smaller, less irritating molecules, making this ingredient suitable for sensitive skin types.
Supports barrier health
The peptides and sugars produced during fermentation can help reinforce the skin's natural moisture barrier, reducing water loss and improving comfort.
Cons and cautions
Limited research
Most evidence comes from lab studies or broader research on fermented ingredients. There are few human clinical trials specifically on this extract, so its benefits are not yet proven.
Variable potency
The quality and activity of the extract can vary between manufacturers and batches, meaning not all products with this ingredient will perform the same way.
Best for
- People with sensitive or easily irritated skin
- Those looking for gentle, fermented skincare ingredients
Use caution if
- Individuals with known yeast allergies should patch test first
- Anyone seeking strong anti-aging or brightening effects may need additional active ingredients
Usage tips
Safety summary
This ingredient is considered safe for topical use in cosmetics at typical concentrations. The fermentation process reduces the risk of irritation. However, individuals with known yeast allergies should exercise caution and perform a patch test.
Research notes
Research on this specific extract is limited. Most supporting evidence comes from studies on fermented plant extracts in general, which suggest potential anti-inflammatory and barrier-supporting benefits. More human studies are needed to confirm its efficacy.
Common label clues
