Science
Mechanism of Action
This ingredient functions by delivering bioactive peptides and fermented metabolites directly to the dermal layer. It stimulates the proliferation of fibroblasts, which are the biological engines responsible for synthesizing Type I collagen and hyaluronic acid, while simultaneously providing antioxidant protection and reinforcing the skin's lipid barrier.

Key findings
- 01 Human monitoring trials conducted by Toyo Hakko Co. (CELABIO-F) demonstrated significant increases in dermal water retention and measurable improvements in skin elasticity and firmness via enhanced fibroblast activity.

Dusting Analysis
Because it is a 'prestige' ferment, brands often include it at negligible levels (<0.5%) for marketing claims. However, clinical data indicates that a minimum concentration of 1% is required to trigger the synthesis of collagen and hyaluronic acid effectively.
The Formula
Formulation
Stability
Heat-sensitive biological extract; efficacy degrades if exposed to temperatures exceeding 50°C. Requires storage in a cool, light-protected environment to prevent denaturation of bioactive proteins.
Synergies
- Niacinamide
- Glycerin
- Ceramides
- Panthenol
Conflicts
- Strong oxidizing agents
- Extreme pH environments
- High heat formulation processes
Safety
Safety Profile
The individual components (Rice, Soy, and Bacillus ferments) are well-established in cosmetic safety databases. EWG assigns a low-hazard score of 1.
