Science
Mechanism of Action
This ingredient functions by releasing bioactive isoflavones, specifically genistein and daidzein, from their glycoside forms through microbial fermentation. These molecules penetrate the skin to trigger natural hyaluronic acid synthesis in both the epidermal and dermal layers, while lactic acid and peptides reinforce the micro-ecological balance and surface integrity.
Research
Clinical Evidence
High confidence10%
Key findings
- 01 A 12-week clinical study demonstrated that a 10% concentration significantly elevated skin elasticity and hydration levels via enhanced endogenous hyaluronic acid production.
- 02 Research into 5% formulations confirmed stable anti-aging benefits and a measurable tensor (tightening) effect in mask applications.
Transparency
Dusting Analysis
While many products list ferments for marketing appeal, clinical efficacy is dose-dependent. Concentrations below 5% may offer basic conditioning but fail to trigger the significant HA synthesis or structural tightening observed in high-performance studies.
The Formula
Formulation
Stability
Naturally acidic (pH ~4.0) due to fermentation metabolites. It is sensitive to thermal degradation and should be processed below 40°C to preserve peptide integrity.
Synergies
- Prebiotics
- Hyaluronic Acid
- Niacinamide
Conflicts
- Strong oxidizing agents
- Strongly alkaline bases (pH > 7.0)
