In recent decades, Hyaluronic acid (HA) has been used as a new polymer in drug delivery – a system that combines traditional drug delivery methods with engineered technology to specifically target where a drug is released in the body and/or the rate at which it gets released. HA was chosen since it has good biocompatibility, … Continue reading
Macromolecule active ingredients (or at least 500KD) are historically difficult or impossible to deliver topically through tissue structures with the limitation of traditional methods. The topical delivery of large molecules through skin, hair, eyes, mucosal surfaces and bone are difficult using high molecular weight hyaluronic acid. In the past, the most common form of hyaluronic … Continue reading

It can bind to specific receptors for which it has a high affinity. The polyanionic form, commonly referred to as hyaluronan, is a visco-elastic polymer found in the aqueous and vitreous humor of the … Continue reading
Hyaluronic acid was discovered in 1934 by British scientist KARL MEYER from bovine eye vitreous body. It is a macromolecule polysaccharide extracted from bovine eye vitreous body. Hyaluronic acid has no species specificity, it widely exists in placenta, amniotic fluid, lens, articular cartilage, skin dermis, and other tissues; it distributes in the cytoplasm and interstitial … Continue reading
Physicochemical properties of hyaluronic acid (HA) HA is a unique linear mucopolysaccharide, which is crosslinked by N-ethylphthalide-glucosamine and D-glucuronic acid. It is widely distributed in the extracellular matrix (such as the vitreous body, joint synovial fluid, cartilage, etc.) of human tissues. It has strong hydrophilicity and high viscoelasticity. There are two kinds of sodium hyaluronate: … Continue reading
