Science
Mechanism of Action
The ingredient utilizes Polymethylsilsesquioxane (PSQ) spherical powders to house an entrapped diamond core. These spheres settle into skin depressions where they perform photoluminescence, converting invisible UV light into visible blue light and scattering blue/green light spectra. This process 'illuminates' wrinkles and dark spots from within, creating a soft-focus effect that physically diminishes the visual depth of skin imperfections.
Research
Clinical Evidence
High confidence1.5%
Key findings
- 01 In-vivo manufacturer trials at 0.5%–1.5% demonstrated immediate optical correction of fine lines and the emergence of a characteristic 'blue glow' luminosity.
- 02 Technical data indicates that concentrations up to 3.0% act as highly effective mattifying agents while significantly reducing the visibility of skin discolorations and shadows via light manipulation.
Transparency
Dusting Analysis
This ingredient is effective at low concentrations (0.1%) for subtle light diffusion; however, inclusion below 0.1% typically suggests a 'label claim' rather than a functional optical benefit, as the photoluminescent spheres require a minimum density to effectively scatter light.
The Formula
Formulation
Stability
The polymer structure is extremely robust and stable across a wide pH range (3–12). It behaves similarly to standard PSQ powders in formulation.
Synergies
- Silicone elastomers
- Refractive index-matched oils
- Mineral pigments
Conflicts
- High-shear mixing (mechanical force can rupture the spherical structure)
- Unstabilized aqueous systems (requires thickening agents for proper suspension)
Safety
Safety Profile
While the specific complex is not yet reviewed by the CIR, its primary constituent, Polymethylsilsesquioxane, is widely recognized as safe with a low-hazard profile (EWG Score: 1).
