What is the principle of hyaluronic acid?

It can absorb 600 times more water than itself, provide support for the organization and maintain the stability and elasticity of the organization. In adults, about 15g of hyaluronic acid is synthesized every day, and then secreted into the extracellular matrix, which mainly plays the role of shrinkage. Hyaluronic acid in normal state has a short retention time in human dermis, and its half-life is only 1-2 days. About 1/3 of hyaluronic acid needs to be metabolized and updated in the body every day. It is mainly degraded into carbon dioxide and water through lymphatic metabolism and liver metabolism. Therefore, hyaluronic acid is a completely biodegradable biomaterial.
