Sodium Hyaluronate Crosspolymer
What is Sodium Hyaluronate Crosspolymer?
Sodium Hyaluronate Crosspolymer is a polymerized derivative of hyaluronic acid, a naturally occurring polysaccharide in the extracellular matrix of human skin and joints. It consists of hyaluronic acid chains cross-linked with a biocompatible agent to form a stable, three-dimensional network. This structure allows it to bind and retain exceptionally large volumes of water, up to hundreds of times its weight. Primarily used in hydrating skincare products like sheet masks, serums, gels, and creams, it functions by swelling upon water contact to create a moist, protective film on the skin surface. This film promotes water influx from the environment or deeper layers, supporting skin barrier integrity and providing prolonged moisture without deep penetration due to its large molecular size. Often produced via fermentation for purity, it enhances product texture for smooth application.
