\"\"<\/figure>

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

What it does:<\/strong><\/h4>\n\n\n\n

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:<\/p>\n\n\n\n

    \n
  1. Long-lasting, resilient hydration:<\/strong> 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.<\/li>\n\n\n\n
  2. Immediate plumping:<\/strong> Provides an exceptional, immediate filling effect.<\/li>\n\n\n\n
  3. Texture modification:<\/strong> Imparts a unique, silky feel to formulas and can help stabilize emulsions.<\/li>\n<\/ol>\n\n\n\n

    Why we use it:<\/strong><\/h4>\n\n\n\n

    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.<\/p>\n\n\n\n

    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.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

    Hyaluronic Acid (HA) vs. Sodium Hyaluronate (SH)<\/h4><\/div><\/div><\/div>\n\n\n\n

    L'Acido Ialuronico (AI)<\/strong> is the free acid form. In its pure state, it is a large polymer chain that is difficult to dissolve in water and is unstable in solution. It is rarely used “as-is” in cosmetic formulas.

    Lo Ialuronato di Sodio (IS)<\/strong> \u00e8 il sale sodico dell'acido ialuronico. Questa \u00e8 la forma stabilizzata e utilizzabile commercialmente. L'aggiunta di sodio lo rende altamente idrosolubile, stabile e capace di penetrare nella pelle in modo pi\u00f9 efficace.

    Pensala cos\u00ec: l'Acido Ialuronico \u00e8 la materia prima<\/em>, mentre lo Ialuronato di Sodio \u00e8 l'ingrediente raffinato<\/em>, stabile e funzionale che si trova nei prodotti per la cura della pelle.

    Nel marketing, i termini AI e IS sono usati come sinonimi perch\u00e9 lo IS non \u00e8 altro che<\/em> AI nel suo stato pi\u00f9 utilizzabile.<\/p><\/div><\/div><\/div>\n\n\n\n
