Science
Mechanism of Action
This ingredient forms a three-dimensional crosslinked network on the stratum corneum. This microscopic matrix fills in fine lines and surface irregularities to physically smooth texture, while simultaneously acting as a breathable, non-occlusive film that limits transepidermal water loss (TEWL) and scatters light to blur imperfections.

Key findings
- 01 Clinical assessments of finished formulations containing 1-5% concentrations showed a significant reduction in apparent wrinkle density by up to 32.9% through optical diffusion and temporary filling.
- 02 Safety evaluations by the CIR confirmed leave-on concentrations up to 23% are non-irritating and safe for ocular-area applications.
Transparency
Dusting Analysis
Because this ingredient significantly impacts the viscosity and 'slip' of a formula, it is rarely used at 'dusting' levels; however, to achieve the measured 32.9% reduction in wrinkle appearance, concentrations should meet or exceed 1%.
The Formula
Formulation
Stability
Exhibits exceptional thermal stability up to 320°C and maintains integrity across a wide pH spectrum. It is cold-processable and helps stabilize the oil phase in complex emulsions.
Synergies
- Dimethicone
- Mineral UV Filters
- Lipophilic Actives
Conflicts
- Strong oxidizing agents
- Highly polar aqueous phases without proper emulsification
