Ingredient review
Yeast Fermented Artichoke Extract
INCI: SACCHAROMYCES/HYDROLYZED STACHYS AFFINIS TUBER FERMENT FILTRATE
A gentle, fermented botanical extract that helps hydrate and protect the skin with antioxidant benefits.
In plain English
This ingredient is made by fermenting Chinese artichoke (a root vegetable) with yeast. The fermentation process breaks down the plant material into smaller, more skin-friendly molecules like amino acids and sugars. In skincare, it acts as a humectant, meaning it pulls moisture into the skin, and also provides antioxidant protection against environmental stressors. It's generally very gentle and suitable for most skin types.

Quick decision guide
Useful, but context matters
Yeast Fermented Artichoke Extract 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 Yeast Fermented Artichoke Extract.
- 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 filtrate obtained after fermenting hydrolyzed Chinese artichoke (Stachys affinis) tubers with Saccharomyces (baker's yeast). The result is a liquid rich in peptides, amino acids, sugars, and other bioactive compounds.
How it works
The small molecules from the fermentation process help attract and retain moisture in the skin's outer layer. The antioxidant compounds can help neutralize free radicals that cause premature aging. It also supports the skin's natural barrier function by providing building blocks for proteins and lipids.
Pros
Gentle hydration
The fermented molecules are small and easily absorbed, providing moisture without clogging pores or feeling heavy.
Antioxidant support
Helps protect skin from daily environmental stressors like pollution and UV exposure, which can lead to premature aging.
Cons and cautions
Limited research
Most evidence comes from studies on the individual components or similar ferments, not this exact ingredient in human skin.
Mild effect
While beneficial, it may not deliver dramatic results on its own and is best used as part of a broader routine.
Best for
- Anyone looking for a gentle, hydrating ingredient that also offers antioxidant protection
- People with dry or dehydrated skin who want a non-greasy moisture boost
Use caution if
- Individuals with a known allergy to yeast or fermented products (rare)
Usage tips
Safety summary
This ingredient has a low irritation and comedogenic risk. It is well-tolerated by most skin types, including sensitive skin. Allergic reactions are very rare but possible in individuals with yeast allergies.
Research notes
Research on fermented plant extracts in general shows benefits for hydration and antioxidant activity. Specific studies on Saccharomyces/Hydrolyzed Stachys affinis Tuber Ferment Filtrate are limited, but the individual components (amino acids, sugars) are well-documented for skin health.
Common label clues
- Typical concentration
- 1–5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU; no specific restrictions.
- Common uses
- Serums, Moisturizers, Essences, Sheet masks
- Environmental note
- The fermentation process is considered a sustainable method of production, using renewable plant biomass and yeast.
Good to know
- Fermentation often increases the bioavailability of plant compounds, making them more effective on skin.
- This ingredient is sometimes listed under a longer INCI name, but the key component is the yeast-fermented artichoke extract.
