Science
Mechanism of Action
The Bacillus fermentation process enzymatically breaks down complex plant cell walls, releasing high-potency bioactive metabolites including sulforaphane, indole-3-carbinol, and phenolic acids. As a postbiotic, it delivers organic acids and peptides that suppress pro-inflammatory signaling pathways (specifically TNF-α and IL-4) while neutralizing oxidative stress at a cellular level.

Key findings
- 01 Topical application in atopic dermatitis models demonstrated a significant reduction in epidermal thickness and pro-inflammatory cytokine expression (2024).
- 02 A 10.0% concentration was clinically shown to prevent barrier disruption in cellular monolayers via soluble metabolites like indole-3-lactate (2025).

Dusting Analysis
Because it is a 'trendy' K-beauty ferment, it is frequently included in ingredient lists at negligible concentrations (<0.5%) for marketing claims. Efficacy for barrier repair typically requires concentrations between 2% and 10%.
The Formula
Formulation
Stability
Maintains structural integrity up to 60°C. Exposure to temperatures exceeding 80°C for extended periods will result in significant loss of enzymatic bioactivity.
Synergies
- Ceramides
- Niacinamide
- Hyaluronic Acid
- Bifida Ferment Lysate
Conflicts
- Strong oxidizing agents
- Formulations with pH > 8.0
