Saccharomyces Ferment
Baker's yeast-derived fermentation extract providing conditioning, brightening, and microbiome-modulating activity. A foundational K-beauty fermentation ingredient.
Benefits
- Skin conditioning via fermentation-derived peptides and amino acids
- Beta-glucan content for immune modulation
- Brightening via fermentation organic acids
- Postbiotic activity
- Vitamin B complex co-fraction
Example uses
- Dry shampoo formulations
- K-beauty brightening layers
- Conditioning toners
- Anti-ageing serums
- Fermented moisturisers
Mechanism of action
Saccharomyces ferment filtrate contains beta-glucan (immunomodulatory, barrier-supporting), amino acids, B vitamins, mannan, and fermentation-derived organic acids. Beta-glucan binds dectin-1 receptors on Langerhans cells in the epidermis, modulating skin immune response. Organic acid fraction contributes mild exfoliation at appropriate pH.
Clinical evidence · Moderate
Beta-glucan mechanisms well-characterised; yeast ferment specific data largely brand-generated. Multiple publications on individual components.
Effective concentration range
0.5–3%
Formulation notes
Aqueous extract; pH stable in cosmetic range. Beta-glucan content provides immune-modulating activity. Active compound profile depends on fermentation process.
Watchouts
Active compound profile varies widely by fermentation conditions and downstream processing. Without standardisation data, clinical comparisons across products are unreliable.
Market positioning
Marketed as multi-benefit fermented yeast active. Beta-glucan and conditioning mechanisms are credible; the full efficacy profile requires product-specific standardisation.
Comedogenicity
0 / 5
Sensitisation risk
Low
