Ingredient review
Rose Ferment Filtrate
INCI: Saccharomyces/Rosa Damascena Flower Extract Ferment Filtrate
A gentle, fermented rose ingredient that may help soothe and protect the skin, but more research is needed to confirm its benefits.
In plain English
This ingredient is made by fermenting rose flower extract with yeast (Saccharomyces). The fermentation process breaks down the rose compounds into smaller molecules, which may make them easier for the skin to absorb. It's often used in skincare products for its potential to calm irritation and provide antioxidant protection against environmental stressors like pollution.

emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A fermented filtrate combining Rosa Damascena (Damask rose) flower extract and Saccharomyces yeast. The fermentation process creates a complex mixture of peptides, amino acids, and plant-derived antioxidants.
How it works
The fermentation process produces bioactive compounds that may help soothe the skin by reducing inflammation and neutralizing free radicals. The smaller molecules from fermentation may also support the skin's natural barrier function.
Pros
Gentle soothing potential
The fermentation process may create compounds that help calm irritated skin without harsh chemicals, making it suitable for sensitive skin types.
Antioxidant support
Rose extracts are rich in antioxidants like vitamin C and polyphenols, which can help protect skin from damage caused by UV exposure and pollution.
Cons and cautions
Limited research
Most evidence for this specific ferment comes from lab studies or traditional use, not large-scale human trials, so its effectiveness is not fully proven.
Potential allergen
While rare, some people may be allergic to rose compounds or yeast byproducts, leading to redness or irritation.
Best for
- People with sensitive or reactive skin looking for a gentle soothing ingredient
- Anyone wanting antioxidant protection in a fermented, potentially more absorbable form
Use caution if
- Individuals with a known allergy to roses or yeast-based ingredients
Usage tips
Safety summary
