Fermented Sugarcane Yeast Extract
INCI: KLUYVEROMYCES/SACCHARUM OFFICINARUM STEM JUICE EXTRACT FERMENT FILTRATE
A gentle, fermented ingredient that may help calm skin and fight free radicals, but research is still early.
In plain English
This ingredient is made by fermenting sugarcane juice with a friendly yeast called Kluyveromyces. The fermentation process creates compounds that can help protect your skin from environmental stress and may reduce redness. Think of it like a gentle, plant-based antioxidant booster for your skincare routine.

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 Sugarcane Yeast 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 fermented filtrate derived from the stem juice of sugarcane (Saccharum officinarum) fermented by the yeast Kluyveromyces. The fermentation breaks down sugars and plant compounds, potentially creating beneficial metabolites like amino acids, peptides, and antioxidants.
How it works
During fermentation, the yeast consumes sugarcane sugars and produces bioactive molecules. When applied to skin, these molecules may help neutralize free radicals (unstable molecules that can damage skin) and support the skin's natural barrier function. Some research suggests fermented ingredients can also have mild soothing effects.
Pros
Gentle on skin
Unlikely to cause irritation, making it suitable for sensitive or reactive skin types.
Antioxidant support
May help protect skin from daily environmental damage like pollution and UV stress.
Cons and cautions
Limited research
Most evidence comes from lab studies or related fermented ingredients, not large human trials on this exact extract.
Variable potency
The quality and activity of the ingredient can differ between batches depending on fermentation conditions.
Best for
- People with sensitive or reactive skin looking for gentle antioxidants
- Anyone interested in fermented skincare ingredients for their potential soothing benefits
Use caution if
- Those with known allergies to sugarcane or yeast-derived ingredients (rare)
Usage tips
Safety summary
Considered safe for topical use with a low risk of irritation or allergic reactions. As with any new ingredient, patch test if you have very sensitive skin.
Research notes
Research on this specific ingredient is limited, but studies on fermented plant extracts in general suggest potential antioxidant and soothing benefits. More human studies are needed to confirm effects.
Common label clues
- Typical concentration
- Typically used at 1-5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU, with no specific restrictions.
- Common uses
- Serums, Moisturizers, Toners
- Environmental note
- Sugarcane is a renewable resource, but its cultivation can have environmental impacts depending on farming practices. Look for brands that source sustainably.
Good to know
- Fermented ingredients are often praised for being more easily absorbed by the skin due to smaller molecule sizes.
- This ingredient is not the same as plain sugarcane extract—the fermentation process changes its properties.
