Scientific name: Sodium Hyaluronate
Classification: Biotechnologically derived glycosaminoglycan polysaccharide
Humectant, elasticity-enhancing, moisturizing.
Stories from Nature
Sodium hyaluronate is the salt form of hyaluronic acid. Its molecules are much smaller than those of hyaluronic acid, allowing them to penetrate more easily into the deeper layers of the skin. It is used in creams, serums, lotions, and moisturizing cosmetic products for the face and body.
One of its best features is its enormous ability to absorb water—up to a thousand times its own weight—which is why it can plump the skin, hydrate it, and reduce wrinkles, thanks to its anti-aging, firming, and elasticity-boosting properties.
It is very well tolerated by the skin, absorbs very well, and is often used in treatments for dry and dehydrated skin and hair.
Benefits for Hair
Sodium Hyaluronate in specific hair care formulations has humectant, elasticizing, and moisturizing properties, resulting in soft, full-bodied hair. It provides volume and hydration, and thanks to the rehydrating and plumping properties of its molecule, hyaluronic acid enhances the internal qualities of the hair’s keratin structure.
Skin Benefits
In the formulas of skin care and sun products face and body products—which offer moisturizing, anti-aging, plumping, and elasticity-boosting effects—four types of sodium hyaluronate molecules are combined: Hydrolyzed Sodium Hyaluronate, Sodium Acetylated Hyaluronate, Sodium Hyaluronate, and Sodium Hyaluronate Crosspolymer: these four forms of hyaluronic acid work synergistically to hydrate the skin at different levels.
High-molecular-weight hyaluronic acid acts on the skin’s surface, creating a protective barrier that retains moisture and reduces transepidermal water loss. The medium-molecular-weight form penetrates the superficial layers, improving hydration and enhancing the skin’s elasticity. The low-molecular-weight form penetrates deeper, stimulating regeneration mechanisms and reducing the appearance of wrinkles and fine lines. Finally, cross-linked hyaluronic acid provides long-lasting hydration, creating a reservoir effect that keeps the skin soft and radiant over time.
In eye care products, sodium hyaluronate acts as a true “moisture magnet,” plumping the eye area and visibly reducing fine lines and signs of dehydration. Thanks to its intense moisturizing action, the skin appears smoother and firmer, regaining its elasticity and softness.
