Science
Mechanism of Action
Forms a cohesive hydrophobic film through polymer chain alignment as solvents evaporate, creating a moisture-resistant barrier that enhances adherence of pigments and active ingredients to skin while providing long-lasting wear properties.
Research
Clinical Evidence
High confidence1.5%
Key findings
- 01 Demonstrated superior humidity resistance and long-lasting hold without stiffness or flaking at 0.3-2.0% concentration
- 02 Provided water resistance and smudge-proof properties with smooth, flexible film formation at 1.0-3.0% concentration
