Sodium Hyaluronate is a sodium salt derived from Hyaluronic acid, which is a medium – high molecular weight polysaccharide. Sodium Hyaluronate is a highly hygroscopic hydrophilic molecule; this means that one molecule of sodium hyaluronate can hold up to 10,000 molecules of water. The different molecular weights intervene at a different level of the epidermis, ensuring a large supply of water, reducing the phenomenon of evaporation and promoting the physiological production of collagen, an essential protein for tissues to maintain the turgor and elasticity typical of youth. Hyaluronic Acid, present in nature as one of the main components of the extracellular matrix, is responsible for several functional activities that give it the following properties: moisturizing, nourishing, emollient, soothing, anti-aging filler, facilitating tissue repair and healing .
