Science
Mechanism of Action
The fermentation process enzymatically breaks down large soybean proteins and starches into low-molecular-weight amino acids and peptides, increasing their bioavailability. It functions as a prebiotic to support a healthy skin microbiome, acts as a humectant to bind moisture within the stratum corneum, and actively suppresses inflammatory markers to reduce redness and irritation.

Key findings
- 01 Concentrations of 0.3% to 1.2% demonstrated a significant reduction in skin erythema and a marked improvement in folliculitis symptoms.
- 02 Usage levels between 1.0% and 5.0% are clinically validated to improve skin elasticity, radiance, and barrier integrity within fermented complexes.
Transparency
Dusting Analysis
Effective results for soothing and erythema reduction begin at 0.3%; formulations containing less than this threshold are likely utilizing the ingredient for label claims rather than physiological impact.
The Formula
Formulation
Stability
The filtrate exhibits exceptional stability across a broad pH range; while often processed at an acidic pH of 3.5, it remains highly stable in final cosmetic vehicles ranging from pH 4.0 to 7.5.
