READ MOREHere is a brief, plain-language overview of the article, written in under 400 characters without efficacy claims. Overview of Hyaluronic Acid in Dry Eye Formulations Hyaluronic acid is a naturally occurring polysaccharide with high water-binding capacity. In solution, its molecular chains form viscoelastic fluids with rheological properties similar to natural tears. Key variables include molecular weight and concentration. High molecular weight HA demonstrates longer ocular retention via mucoadhesion. HA interacts with CD44 receptors and influences inflammatory pathways. Formulation parameters include pH, osmolarity, and preservative systems.
