Science
Mechanism of Action
This ferment functions by breaking down rice bran’s structural proteins into smaller amino acid chains that penetrate more effectively while simultaneously producing a pullulan-rich film on the skin's surface. It acts as a bio-mimetic humectant that stabilizes the microbiome, inhibits tyrosinase activity to manage hyperpigmentation, and triggers fibroblasts to increase the synthesis of essential collagen and elastin fibers.

Key findings
- 01 A 20% concentration demonstrated a 44.31% surge in skin hydration and a 9.29% reduction in melanin levels over 30 days.
- 02 In vivo testing at 10% concentration confirmed a significant >10% boost in collagen and elastin synthesis alongside reduced TEWL.
- 03 Usage at 2% facilitates the formation of an elastic water-gel film that improves immediate barrier resilience.

Dusting Analysis
Due to its complex INCI name and perceived 'natural' appeal, it is often included at concentrations below 0.5% for marketing claims. However, clinical data suggests a minimum of 2% is required for film-forming benefits, and 10-20% for significant structural anti-aging and brightening results.
The Formula
Formulation
Stability
Highly stable, nonionic ingredient that maintains integrity across broad pH ranges and exhibits excellent electrolyte resistance. It can naturally thicken formulas into sprayable gels.
Synergies
- Niacinamide
- Hyaluronic Acid
- Vitamin C derivatives
Conflicts
- High concentrations of ammonium sulfate
Safety
Safety Profile
While the specific ferment is not yet indexed by CIR, its base components (Rice Bran and Pullulan) are widely recognized as safe. It is ECOCERT certified and demonstrates high biocompatibility.
