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
Sodium hyaluronate is the sodium salt of hyaluronic acid, a glycosaminoglycan found in various connective tissue of humans, it occurs naturally in the human body and is central to regulating cell growth and renewal. In fact, it is found extensively in connective, epithelial, and neural cells. As such, hyaluronic acid has found its way into … Continue reading
Sodium hyaluronate is the sodium salt of hyaluronic acid. It is a glycosaminoglycan and long-chain polymer of disaccharide units of Na-glucuronate-N-acetylglucosamine. 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
In recent years, the skin care industry has undergone tremendous changes Today, let’s talk about hyaluronic acid. Let’s start with the basics. Hyaluronic acid is a natural biological molecule widely existing in the skin and other tissues. It plays an important physiological role in water retention, extracellular space maintenance and cell repair. A large number … Continue reading
Hyaluronic acid can be used as the eye intraocular lens implant surgery viscoelastic agent, osteoarthritis and rheumatoid arthritis and other joint operation of filling agent, as a medium is widely used in eye drops, also used for the prevention of postoperative adhesion and promote the healing of skin wound. Hyaluronic acid (HA) is a straight … Continue reading
It’s so easy to buy pure hyaluronic acid powders these days. And it’s quite easy to learn how to use. However, it’s more difficult to understand what makes your hyaluronic acid products work, let alone know how to see the maximum effect of hyaluronic acid. Never fear–we’re here to help you become a smart, informed the … Continue reading
Osteoarthritis is a joint disease characterized by the loss or degeneration of cartilage and bone reaction around the joint. The intrinsic pathogenesis of osteoarthritis is that the articular cartilage loses its elasticity due to mechanical trauma or chronic inflammation. Under the action of lubrication, the articular cartilage surface is damaged and destroyed, and then osteophyte … Continue reading
