Sodium Hyaluronate Crosspolymer

INCI: SODIUM HYALURONATE CROSSPOLYMER
Type: Film-forming humectant, skin conditioning
Origin: A modified form of Sodium Hyaluronate where the hyaluronic acid chains are chemically cross-linked to create a larger, three-dimensional network or mesh.

What it does:

This is an advanced, engineered derivative of hyaluronic acid designed for enhanced performance and unique sensory properties. Its primary functions are distinct from standard sodium hyaluronate:

1. Long-lasting, resilient hydration: The cross-linked polymer forms an elastic, breathable film on the skin’s surface that is more resistant to being washed or rubbed off. This creates a sustained reservoir of hydration that releases moisture over time.
2. Immediate plumping: Provides an exceptional, immediate filling effect.
3. Texture modification: Imparts a unique, silky feel to formulas and can help stabilize emulsions.

Why we use it:

We include it as part of our 5-weight hyaluronic acid complex in our daily moisturiser. It is responsible for delivering an immediate smooth, plumped feel and locking in a layer of lasting moisture that complements the work of the other penetrating HA molecules.

The cross-linking creates a much larger molecular structure that remains on the skin’s surface, acting as a sophisticated “moisture magnet” rather than a penetrative hydrator. It provides long-lasting surface hydration and film-forming benefits.
