What is hyaluronic acid?

Hyaluronic acid (HA) is a substance that occurs naturally in the human body, found primarily in the skin, connective tissues, and eyes. It binds and retains water, providing lubrication and moisture wherever it’s present. In the skin, HA plays a crucial role in maintaining elasticity and hydration, helping skin look smoother and plumper. By boosting moisture content, it also helps reduce the appearance of fine lines and wrinkles. Most skincare formulations use a bioidentical version of HA — or one of its salt forms, such as sodium hyaluronate — produced through fermentation to precisely match the molecule your body already makes.
