Science
Mechanism of Action
The fermentation process acts as a molecular refiner, transforming large isoflavone glycosides into smaller, more penetrative aglycones like genistein and daidzein. On a cellular level, it stimulates fibroblast activity to increase Type I collagen synthesis while simultaneously inhibiting the tyrosinase enzyme to disrupt melanin production, all while replenishing the skin’s Natural Moisturizing Factor (NMF) with essential amino acids and small-chain peptides.

Key findings
- 01 A 2% concentration demonstrated significant structural improvements in skin elasticity and a measurable reduction in fine line depth through enhanced collagen bioavailability.
- 02 At a 5% concentration, the filtrate exhibited potent depigmenting properties by successfully inhibiting tyrosinase activity and reducing melanin synthesis in cellular models.
Transparency
Dusting Analysis
While many formulas include fermented soy for label appeal at low concentrations (under 1%), clinical data suggests that a minimum of 2% is required for anti-aging benefits and 5% for visible brightening effects.
The Formula
Formulation
Stability
Highly stable in aqueous solutions but thermo-sensitive; bioactive isoflavones may degrade if exposed to temperatures exceeding 40°C or prolonged UV radiation.
Synergies
- Niacinamide
- Hyaluronic Acid
- Vitamin C derivatives
Conflicts
- Strong oxidizing agents
- Extreme pH environments (below 4.0 or above 7.0)
Safety
Safety Profile
Classified as Generally Recognized as Safe (GRAS); it is a non-pathogenic, food-grade derivative suitable for long-term topical use.
