Science
Mechanism of Action
The polymer organizes into a flexible, continuous matrix upon application, functioning as a substantive shield that prevents trans-epidermal water loss (TEWL). By cross-linking fatty acids with a polyurethane backbone, it enhances the skin's physical barrier while providing a refractive surface that significantly boosts topical radiance.

Key findings
- 01 Manufacturer technical trials indicate superior film substantivity and gloss enhancement at 1-5% concentrations.
- 02 Related Dilinoleic Acid/Glycol copolymers have demonstrated significant clinical reduction in skin dryness and visible scratch marks in xerosis patients at higher inclusion rates.
