Science
Mechanism of Action
It acts as a structural opacifying agent and light diffuser. By utilizing precisely shaped glass flakes, it scatters light across the skin's surface to minimize the appearance of fine lines while physically improving the 'slip' of the product during application.
Research
Clinical Evidence
High confidence31%
Key findings
- 01 A 31% concentration was validated via Human Repeat Insult Patch Test (HRIPT) as non-sensitizing and non-irritating.
- 02 In vitro EpiOcular™ testing at 100% concentration confirmed the ingredient is a non-irritant for the ocular area.
Transparency
Dusting Analysis
This is an aesthetic and structural additive rather than a bioactive; it is typically used at meaningful percentages (up to 33%) to achieve visible optical results.
The Formula
Formulation
Stability
Highly stable and chemically inert glass flakes. They remain insoluble in both water and oil phases but can be surface-treated for better dispersion.
Synergies
- Dimethicone
- Silica
- Mineral UV filters
Conflicts
- High-shear milling (fractures the glass flakes)
- Environments below pH 3.0 (potential leaching risk)
Safety
Safety Profile
Chemically inert and does not penetrate the skin barrier, making it safe for use during pregnancy. It has been used up to 97% in lip products without adverse effects.
