Science
Mechanism of Action
It functions via ionic signaling to maintain the epithelial barrier, preserving transepithelial electrical resistance (TEER) even under environmental stress. Beyond its role as a humectant and pH-stabilizing buffer, it acts as a sebum-regulating agent and provides essential minerals for cellular enzymatic processes and healthy skin turnover.
Research
Clinical Evidence

Key findings
- 01 Observed a 15% increase in skin elasticity over 12 weeks of consistent application.
- 02 Demonstrated significant preservation of barrier function and reduced permeability under hypoxic stress.
Transparency
Dusting Analysis
Because it is effective at very low concentrations for barrier signaling, brands often include it at negligible levels ('dusting') to claim mineral benefits without achieving the 1.0% threshold required for measurable elasticity improvements.
The Formula
Formulation
Stability
Sparingly soluble in water (1.1%-1.3%); best maintained in neutral to slightly alkaline environments. It is frequently utilized to buffer and stabilize acidic formulas.
Synergies
- Hyaluronic Acid
- Peptides
- Ceramides
Conflicts
- High-concentration ethanol
- Strong oxidizing agents
- Certain anionic surfactants (may cause mineral precipitation)
