Science
Mechanism of Action
This innovative cross-linked hyaluronic acid derivative forms a unique three-dimensional 'infinite mesh' on the skin, creating a persistent moisture-binding film. It acts as a continuous hydration reservoir, gradually releasing water to prevent transepidermal water loss and significantly enhance skin elasticity. Its superior cross-linked structure grants it exceptional stability against enzymatic degradation and a remarkable water-binding capacity, up to five times greater than conventional hyaluronic acid. Furthermore, it actively scavenges free radicals and bolsters the skin's natural barrier function.

Key findings
- 01 Recommended for topical cosmetic products within the 0.01-0.1% concentration range, with safety tests supporting use up to 1%. It provides long-term moisturizing benefits and contributes to wrinkle reduction.
- 02 A pilot comparative study demonstrated that topical application of a cross-linked resilient hyaluronic acid significantly reduced transepidermal water loss (TEWL) by 27.8%, a superior outcome compared to the 15.6% reduction observed with high molecular weight hyaluronic acid.
- 03 Studies indicate that Sodium Hyaluronate Crosspolymer can enhance skin hydration by up to 62% within a single hour, outperforming high-molecular weight hyaluronic acid.

The Formula
Formulation
Stability
This polymer is heat-sensitive and susceptible to decomposition at extreme pH levels (below 4 or above 10), with heating accelerating this process. It maintains stability for 2 hours at 70°C or 24 hours at 50°C at a neutral pH of 7.
Conflicts
- strong oxidation agents
- strong reduction agents
- polymeric cationic substances (e.g., cationic surfactants, Polyquaternium-4, Polyquaternium-10)
- multivalent metals (e.g., Zn2+, Mg2+) which can alter the crosslinked network quality
Safety
Safety Profile
While the Cosmetic Ingredient Review (CIR) Expert Panel's 2023 assessment of hyaluronates explicitly excluded cross-linked hyaluronic acid, this ingredient is widely considered safe for cosmetic use. It is non-toxic, non-irritating, and presents a low risk of allergic reactions, aligning with the established safety profile of related hyaluronates such as Sodium Hyaluronate.
