99% Hyaluronic Acid Powder Sodium Hyaluronate for Cosmetics Material
Product Description
Sodium Hyaluronate (SH) is the sodium salt form of hyaluronic acid (HA)—a naturally occurring glycosaminoglycan found in human connective tissues, skin, eyes, and joints. Unlike hyaluronic acid itself (a high-molecular-weight polymer with limited solubility), sodium hyaluronate boasts exceptional water solubility and smaller molecular size, enabling it to penetrate more deeply into tissues (such as skin layers) while retaining the same extraordinary moisture-binding capacity.

Product Function
1.Intensive, Long-Lasting Hydration.
As a “moisture magnet,” sodium hyaluronate forms a protective, breathable film on the skin’s surface that traps existing moisture, preventing transepidermal water loss (TEWL)—a major cause of dryness, dullness, and flakiness.
2.Skin Barrier Repair & Anti-Aging Support
The dermis naturally contains hyaluronic acid, which declines with age, leading to loss of elasticity, fine lines, and wrinkles.
3.Joint Health & Mobility
In the human body, hyaluronic acid acts as a lubricant and shock absorber in joint synovial fluid. Sodium hyaluronate, when used in supplements or injectable formulations, replenishes depleted synovial fluid, reducing friction between cartilage surfaces.
4.Ocular Health Protection
The eyes’ vitreous humor and tear film rely on hyaluronic acid for moisture and lubrication.
5.Wound Healing & Tissue Regeneration
Sodium hyaluronate supports the wound-healing process by creating a moist environment that accelerates cell proliferation and tissue repair.
