Science
Mechanism of Action
This copolymer functions by forming an advanced, breathable, yet non-occlusive polymeric matrix upon application to the skin. This layer structurally improves the aesthetic and functional characteristics of cosmetic formulations, extending attributes such as water resistance and product longevity. Concurrently, this film aids in creating a barrier that supports the retention of dermal moisture.
