Sodium hyaluronate is the water-soluble salt of form of hyaluronic acid (HA) that are bio-engineered to increase its stability and reduce the likelihood of oxidisation.
Both sodium hyaluronate and HA can be commonly found in skin care products and cosmetics to hydrate and retain skin moisture. As compared to HA, sodium hyaluronate has a smaller molecular size that allows it to penetrate into deeper layers of the skin. When applied topically, it can reach deep down into dermis to attract water and promote nutrients absorption, resulting in a softer, smoother and fuller appearance.
Other than beauty industry, sodium hyaluronate injection is also used to treat knee pain associated with osteoarthritis when patients have not responded well to the other arthristis medications. It acts as a lubricant and shock absorber in the joint, allowing the knee to move smoothly, thereby lessening pain.
