Injection Grade hyaluronic acid Powder
Injection-grade hyaluronic acid (HA) is a highly purified, sterile form of sodium hyaluronate designed for medical applications. It is widely used in joint injections for osteoarthritis, as a dermal filler in cosmetic procedures, and in ophthalmic surgeries. Its high biocompatibility and excellent viscoelastic properties make it suitable for restoring tissue volume, reducing wrinkles, and improving joint function. Various molecular weights of HA are used depending on the specific application.

Description of injection grade HA powder
Injection-grade hyaluronic acid (HA) is characterized by its high purity, being free from contaminants like proteins and nucleic acids. It is sterilized and packaged in a form suitable for medical injections, ensuring safety and effectiveness. HA’s excellent viscoelasticity makes it ideal for joint lubrication and soft tissue augmentation. Its biocompatibility reduces the risk of allergic reactions or immune responses. Additionally, HA comes in various molecular weights including high molecular weight, middle molecular weight, and low molecular weight, with each type tailored to specific injection applications.

Chemical Composition of injection grade HA powder
Osteoarthritis: Used in viscosupplementation, where HA is injected into joints (e.g., knees) to reduce pain and improve joint function.
Dermal Fillers: HA injections are widely used in cosmetic procedures to reduce wrinkles, restore facial volume, and enhance lips.
Ophthalmic Surgery: Used during eye surgeries such as cataract removal to maintain space, protect cells, and facilitate healing.
Wound Healing: Some HA injections are used to promote healing in wounds and ulcers.
Drug Delivery Systems: HA can serve as a carrier for drugs in injectable formulations, improving delivery and prolonging the effect.
