Science
Mechanism of Action
This versatile copolymer operates on multiple fronts within a formulation, primarily functioning as a texture enhancer, thickener, binder, and suspension stabilizer. Upon application to the skin, it establishes a flexible, protective film that significantly reduces transepidermal water loss, thereby augmenting skin hydration. This film-forming characteristic can also facilitate the sustained, gradual release of incorporated active ingredients. Its inherent ability to rapidly absorb water results in a smooth, gel-like consistency, enhancing the sensory experience during product use.
