　　Hyaluronic acid is a naturally occurring substance found in all mammals that helps to hydrate and add volume to your skin. In addition to its use as an aesthetic treatment, hyaluronic acid has also been used for more than 20 years for injection into arthritic joints to aid movement as well as for eye surgeries and wound repair.

　　“Uncross-linked” hyaluronic acid in its natural form is in a liquid state. “Cross-linking” is the process through which hyaluronic acid is made into a gel product that can be injected into the skin for long-lasting results.
