Hyaluronic acid is an acidic mucopolysaccharide first isolated from bovine vitreous humor. Its unique molecular structure and physicochemical properties enable multiple vital physiological functions within the body, such as lubricating joints, regulating vascular permeability, modulating protein and water/electrolyte diffusion and transport, and promoting wound healing.
Most notably, hyaluronic acid possesses exceptional water-retaining properties, making it the most effective natural moisturizer discovered to date. It is recognized as an ideal Natural Moisturizing Factor (NMF). For instance, a 2% pure hyaluronic acid solution can firmly retain 98% moisture. As a multifunctional matrix, hyaluronic acid (HA) is widely distributed throughout the human body.
The skin contains substantial amounts of hyaluronic acid. The maturation and aging processes of human skin are closely linked to its hyaluronic acid content and metabolic activity. It enhances skin nutrition metabolism, resulting in softer, smoother skin, reduced wrinkles, increased elasticity, and anti-aging effects. While providing hydration, it also acts as an excellent transdermal absorption enhancer. When combined with other nutrients, it significantly improves nutrient absorption efficiency.
