INCI:<\/strong> HYALURONIC ACID | SODIUM HYALURONATE
Type:<\/strong> Humectant, skin conditioning
Origin:<\/strong> A glycosaminoglycan (GAG) naturally abundant in human skin, connective tissue, and joints. Commercially, it is produced via bacterial fermentation (typically from Streptococcus<\/em> species), which is the standard for high-purity, sustainable cosmetic-grade HA.<\/p>\n\n\n\n

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

Hyaluronic Acid (HA) is a powerful, natural humectant renowned for its extraordinary capacity to hold water \u2013 up to 1000 times its own weight. It does not work by adding moisture but by binding and retaining it within the skin’s layers.<\/p>\n\n\n\n

    \n
  1. Idratazione multi-livello:<\/strong> Achieved through different molecular weights that range from <10 kDa to 1000+ kDa.\n
      \n
    • High-molecular-weight HA<\/strong> (>1000 kDa): Forms a breathable, hydrating film on the skin’s surface, providing immediate smoothing and plumping.<\/li>\n\n\n\n
    • Low-molecular-weight HA<\/strong> (<10 \u2013 1000 kDa): Can penetrate deeper into the epidermis, drawing water into the living skin cells for longer-lasting hydration and support.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Skin barrier support:<\/strong> By maintaining optimal hydration levels, it helps keep the stratum corneum supple and resilient, reinforcing the skin’s natural barrier function.<\/li>\n<\/ol>\n\n\n\n

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

      We use a multi-molecular-weight HA (a proprietary 5-weight complex) as the hydration cornerstone in our daily moisturiser. This blend ensures both immediate surface smoothing and deep-skin hydration for a visibly plump, resilient, and better-looking complexion.<\/p>\n\n\n\n

      As a substance your body produces naturally, it is exceptionally well-tolerated by all skin types.<\/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
