Science
Mechanism of Action
This ingredient employs a triple-action pathway: volcanic minerals like sulfur and magnesium regulate sebaceous gland activity, while Job's Tears supply coixenolide and amino acids to soothe and brighten. The Bacillus fermentation process further breaks these components into low-molecular-weight peptides and organic acids that support the skin microbiome and promote gentle enzymatic exfoliation.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 A 3.0% concentration demonstrated a statistically significant reduction in sebum secretion and visible pore diameter over a 4-week period.
- 02 In-vitro analysis of concentrations between 1.0% and 5.0% showed an upregulation of filaggrin and aquaporin-3, indicating enhanced hydration and barrier protein synthesis.
Transparency
Dusting Analysis
While often featured in marketing for its 'volcanic' origins, clinical data suggests a minimum of 1.0% is required to activate barrier-strengthening properties, with 3.0% necessary for significant oil control.
The Formula
Formulation
Stability
The filtrate is highly stable in aqueous systems but is thermolabile; it must be incorporated during the cooling phase at temperatures below 40°C to maintain the integrity of fermented metabolites.
Synergies
- Niacinamide
- Hyaluronic Acid
- Panthenol
- Zinc PCA
Conflicts
- Ethanol concentrations exceeding 20%
- Strong oxidizing agents
- Formulations with a pH below 3.5
Safety
Safety Profile
The individual components (Coix and Volcanic Ash) have a long history of safe cosmetic use, and Bacillus ferments are generally recognized as safe for topical applications.
