Sodium hyaluronate (hyaluronic acid, HA) is of some thousands to a few millions of Daltons (Da) molecular weight (MW). Physical properties and biological functions such as viscosity, permeability, moisturization, anti-inflammatory action, lubrication depend altogether only on molecular weight variation. Therefore, when selecting sodium hyaluronate, one should select the most suitable molecular weight based on the … Continue reading
Molecular weight is one of the most significant properties of hyaluronic acid (HA). Different molecular weights have different physicochemical properties and biological activities. High molecular weight hyaluronic acid (HMW-HA), typically above 1,800 kDa, has superior viscosity, lubrication, and stability properties and is of great benefit in skincare and medical therapy. The Powerful Lubricating Effects of … Continue reading
When people hear of hyaluronic acid (HA), the majority of them will immediately associate it with cosmetic and skincare applications. Whether applied as dermal fillers or as a means to improve skin hydration, HA is indeed highly effective. But the application of HA extends far beyond these.

Throughout these stages, hyaluronic acid plays an active role, hence it qualifies as an ideal material for wound healing. What is Hyaluronic Acid Hyaluronic acid (Hyaluron, HA) is a naturally occurring polysaccharide molecule found in humans and other organisms. It is widely distributed … Continue reading
Hyaluronic acid is a naturally occurring ingredient in the human body, known for its excellent moisturizing, lubrication, and biocompatibility. These merits have led to a wide variety of applications in medicine and cosmetics. According to its purpose, HA can be divided into cosmetic-grade, food-grade, medical-grade, and injectable-grade. Of them, injectable-grade HA is extensively used in … Continue reading
Introduction to Sodium Hyaluronate Hyaluronic acid (HA) is a high-molecular-weight polysaccharide with repeating disaccharide units of D-glucuronic acid and N-acetylglucosamine. Its salt form, sodium hyaluronate (SH), was initially isolated from the eye’s vitreous body. Sodium hyaluronate has a wide distribution in animal or human tissues, generally located in the extracellular matrix. It has a high … Continue reading
Polyglutamic acid (γ-PGA) is a non-toxic, eco-friendly polymer that is safe for humans. It is synthesized naturally within organisms and has excellent biocompatibility, biodegradability, and biological safety. Because of these properties, it is widely used in skincare, agriculture, food, environmental, and medical fields. Polyglutamic Acid in Skincare: High-Efficiency Moisturizer γ-PGA is capable of absorbing 5,000 … Continue reading
