INCI: SACCHAROMYCES/BARLEY SEED FERMENT EXTRACT
A gentle, fermented ingredient that helps soothe and hydrate the skin, making it a good choice for sensitive or irritated skin types.
In plain English

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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A fermented extract created by culturing Saccharomyces (a type of yeast) on barley seeds. The fermentation process produces a complex mixture of peptides, amino acids, sugars, and other bioactive compounds that can benefit the skin.
How it works
When applied to the skin, the extract provides a source of amino acids and sugars that help maintain the skin's natural moisture barrier. It also has mild anti-inflammatory properties, which can help reduce redness and irritation. It works by supporting the skin's own repair processes rather than forcing a change.
Pros
Soothing effect
The fermentation process creates compounds that can help calm redness and irritation, making it a good option for reactive skin.
Lightweight hydration
It provides moisture without feeling heavy or sticky, so it works well under makeup or in humid climates.
Cons and cautions
Subtle effects
This is a supportive ingredient, not a powerhouse active. You may not see dramatic changes if you're targeting deep wrinkles or hyperpigmentation.
Limited research
Most evidence comes from ingredient-level studies or broader research on ferments, not large clinical trials on this exact extract.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, hydrating ingredient in their routine
Use caution if
- Individuals with a known allergy to barley or yeast (rare)
Usage tips
Safety summary
This ingredient has a low irritation and comedogenic risk. Allergic reactions are very rare but possible in individuals with specific grain allergies. It is considered safe for use in cosmetics at typical concentrations.
Research notes
Research on fermented ingredients in general supports their ability to improve skin hydration and reduce inflammation. However, specific studies on Saccharomyces/Barley Seed Ferment Extract are limited, and most evidence is extrapolated from similar ferments or ingredient-level analysis.
Common label clues
- Typical concentration
- 1–10% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used as intended.
- Common uses
- Serums, Moisturizers, Toning Lotions, Sheet Masks
- Environmental note
- Barley is a widely grown crop with a relatively low environmental footprint, and fermentation is a natural, low-energy process.
Good to know
- Fermented ingredients like this one are often well-tolerated because the fermentation process breaks down larger molecules that might otherwise cause irritation.
- It is often found in products marketed as 'probiotic' or 'fermented' skincare, though it does not contain live bacteria.
