Science
Mechanism of Action
This ingredient profoundly benefits the skin through multiple pathways. It acts as a powerful humectant, drawing and locking in moisture to deeply hydrate the stratum corneum and drastically reduce transepidermal water loss. By combating free radicals and reducing inflammation, it provides robust antioxidant protection. Furthermore, it stimulates collagen production and cellular respiration, improving skin elasticity, texture, and promoting regeneration. Its soothing properties alleviate redness, regulate sebum, and it supports the skin's natural microbiome, contributing to a brighter, more even complexion by inhibiting melanin synthesis.

Key findings
- 01 Continuous application of a spray containing 5% Saccharomyces boulardii fermented product filtrate over four weeks demonstrated a notable 37.2% reduction in trans-epidermal water loss (TEWL) and a substantial 62.5% increase in stratum corneum hydration.
- 02 Topical formulations containing 5% Saccharomyces cerevisiae extract, recognized as Saccharomyces Ferment Filtrate, significantly improved skin hydration and microrelief, enhancing TEWL and skin texture after 30 days of daily use, surpassing a vitamin-enriched control.
- 03 A formulation containing the fermentation residue of Saccharomyces cerevisiae exhibited increased skin whitening activity in a clinical study when compared to a control group.
Transparency
Dusting Analysis
Clinical research indicates significant efficacy at concentrations of 5%, which aligns with the Cosmetic Ingredient Review (CIR) Expert Panel's maximum recommended concentration for leave-on products. There is no evidence suggesting this ingredient is commonly used at sub-efficacious levels to falsely claim benefits.
The Formula
Formulation
Stability
Saccharomyces Ferment Filtrate is stable up to 60°C and should be incorporated during the cooling phase of a formulation. For optimal shelf life, typically 12-24 months, store at 23-25°C, though a range of 16-32°C is permissible. Freezing is not recommended.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Saccharomyces Ferment Filtrate is safe for use in cosmetics under current practices, provided specific criteria such as non-pathogenicity and impurity limits are met. It is generally well-tolerated, with rare reports of allergic reactions or irritation. Recommended usage in leave-on products ranges from 0.1% to 5%.
