Science
Mechanism of Action
This copolymer primarily creates a resilient film on the skin's surface, leveraging its film-forming properties. As a plasticizer, it boosts the flexibility and longevity of this protective barrier. Furthermore, the polypropylene glycol components inherently condition the skin by forming a hydrating layer, effectively minimizing moisture loss and contributing to improved lubrication.
