What is the difference between blunt needle fat filling and hyaluronic acid filling

Hyaluron cacid (Hyaluronan,HA), also known as hyaluronic acid, is a group of very small amounts of polysaccharide, which is the same form of hyaluronan that bacteria or humans have. Natural HYALURONIC ACID (HA) IS A MUCOPOLYSACCHARIDE (MUCOPOLYSACCHARIDE), A LINEAR POLYMER CONSISTING OF REPEATED SEQUENCES OF D-GLUCURONIC ACID AND N-ACETYLGLUCOSAMINE DIMERS. It is widely distributed in the extracellular matrix of connective tissues such as skin, vitreous, aqueous humor, synovial fluid and placenta in Suckling and human body, and in various parts of the machine. It has no species or tissue specificity, so the body rarely mounts an immune response to it. Hyaluronic acid usually exists as a free polymer in tissues, which binds to disaccharide units and has high electronegativity, but in cartilage, bone and other tissues, hyaluronic acid mostly binds to glycoproteins or specific cell receptors.

Hyaluronic acid is a multifunctional matrix, which has important physiological functions such as lubrication, water retention and buffering, changing the diffusion rate of substances in the skin, maintaining the normal permeability of the arterial wall, and regulating the flow and concentration of ions around cells. It is also involved in various inflammatory reactions and can scavenge free radicals. Hyaluronic acid is highly hydrophilic and water-retaining, and can absorb up to 1,000 times its weight in water. In this way, hyaluronic acid can still become a gel even at a very low concentration. After hyaluronic acid absorbs water, its volume increases, and the swelling pressure generated around it makes it able to support the surrounding tissue. These properties make hyaluronic acid an ideal filler for maintaining tissue morphology and function!
