Ingredient review
Schizosaccharomyces Ferment Filtrate
INCI: Schizosaccharomyces Ferment Filtrate
A gentle fermented yeast extract that may help hydrate and support the skin barrier, though more human studies are needed.
In plain English
This is a liquid made by fermenting a type of yeast called Schizosaccharomyces pombe. The fermentation process creates a broth rich in amino acids, vitamins, and other small molecules that can be absorbed by the skin. It's similar to other popular fermented ingredients like galactomyces ferment filtrate but from a different yeast species. In skincare, it's used to provide hydration and support the skin's natural barrier without causing irritation.

Quick decision guide
Useful, but context matters
Schizosaccharomyces Ferment Filtrate 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 Schizosaccharomyces Ferment Filtrate.
- 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A filtrate obtained after fermenting Schizosaccharomyces pombe yeast, containing peptides, amino acids, and other bioactive compounds.
How it works
The small molecules from the fermentation process can penetrate the upper layers of the skin, where they may help attract and retain moisture (humectant effect) and support the skin's natural repair processes. Some research suggests it can also help regulate oil production and calm inflammation.
Pros
Gentle hydration
Provides moisture without common irritants, making it suitable for sensitive or reactive skin types.
Barrier support
May help reinforce the skin's natural barrier, reducing water loss and improving overall skin resilience.
Cons and cautions
Limited evidence
Most research is lab-based or on related yeast ferments; direct human studies on Schizosaccharomyces pombe are sparse.
Variable potency
The concentration and quality of active compounds can differ between brands and batches, so results may not be consistent.
Best for
- People with dry or dehydrated skin looking for extra hydration
- Those interested in fermented skincare ingredients with a low irritation risk
Use caution if
- Individuals with a known allergy to yeast or fermented ingredients (rare)
Usage tips
Safety summary
Schizosaccharomyces Ferment Filtrate is considered safe for topical use with a low risk of irritation or allergic reactions. It is non-comedogenic and well-tolerated even by sensitive skin. As with any new ingredient, a patch test is recommended.
Research notes
Research on this specific ferment is limited, but related yeast ferments (e.g., galactomyces) have shown benefits for hydration and barrier function. Preliminary lab studies suggest antioxidant and anti-inflammatory potential, but more human trials are needed to confirm efficacy.
Common label clues
- Typical concentration
- 1–10% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in most regions including the EU, US, and Asia. No specific restrictions.
- Common uses
- Serums, Moisturizers, Essences, Toner
- Environmental note
- Produced via controlled fermentation, which is generally considered a low-impact, sustainable process compared to some plant extracts.
Good to know
- This ingredient is often found in Korean and Japanese skincare products as a gentler alternative to other ferments.
- It has a slightly acidic pH, which can help maintain the skin's natural acid mantle.
