Science
Mechanism of Action
Through a controlled fermentation process using Bacillus bacteria in a glycerin medium, large molecules within the Brassica napus are biotransformed into smaller, highly absorbable fragments. These include bioactive peptides and sinapic acid, which neutralize oxidative stress and serve as prebiotic fuel to balance the skin's microbiome and fortify the lipid barrier.

Key findings
- 01 In-vitro and ex-vivo evaluations demonstrate that the fermentation process significantly elevates the presence of sinapic acid, resulting in superior barrier recovery and radical scavenging compared to standard rapeseed extracts.

Dusting Analysis
As a complex ferment, this ingredient is often included at 'label-claim' levels (below 1%) in mass-market products. To achieve the documented improvements in barrier resilience and antioxidant capacity, a concentration between 1% and 5% is required.
The Formula
Formulation
Stability
Heat-sensitive; must be integrated during the cooling phase (below 40°C) to maintain the integrity of the ferment-derived bioactives. Stable in O/W emulsions.
Synergies
- Niacinamide
- Hyaluronic Acid
- Ceramides
Conflicts
- Strong oxidizing agents
- Highly acidic formulations below pH 3.5
Safety
Safety Profile
While the specific filtrate is undergoing further literature review as of 2025, its constituent components—Glycerin and Bacillus Ferment—are recognized as safe for topical application.
