Science
Mechanism of Action
The fermentation process utilizes Bacillus species to biotransform soybean isoflavone glycosides into bioactive aglycones like genistein and daidzein, while simultaneously breaking down Heartleaf proteins into low-molecular-weight peptides. This molecular refinement enhances the concentration of flavonoids, which actively inhibit elastase to protect collagen structures and suppress pro-inflammatory cytokines to stabilize reactive skin.

Key findings
- 01 Concentrations of 1-5% demonstrate significant increases in quercetin and total phenolics, leading to measurable anti-wrinkle effects via elastase inhibition.
- 02 In vitro tests at 100-200 μg/mL show over 95% superoxide anion inhibition, providing robust protection for fibroblasts against oxidative stress.
Transparency
Dusting Analysis
Due to the prestige of 'fermented' ingredients in K-beauty, this filtrate is frequently added at sub-clinical levels (<1%) for marketing claims. To achieve the documented antioxidant and anti-elastase benefits, it should be present as a primary liquid or at a minimum of 1%.
The Formula
Formulation
Stability
The filtrate is heat-stable up to 60°C and maintains integrity at room temperature. It is often co-processed with volcanic scoria to neutralize the characteristic pungent aroma of the fermentation process.
Synergies
- Niacinamide
- Hyaluronic Acid
- Panthenol
Conflicts
- Strong oxidizing agents
- Extreme pH environments below 3.5 or above 8.5
- High concentrations of alcohol
Safety
Safety Profile
While the specific three-part complex is pending a formal CIR review, the individual components (Bacillus Ferment, Soybean, and Houttuynia Cordata) have long-standing safety profiles in cosmetic use.
