Mechanism of action

Hyaluronic acid is a naturally occurring polysaccharide that acts as a viscoelastic agent, providing lubrication and moisture retention on the cornea and conjunctiva. The preservative-free formulation reduces irritation from chemical preservatives, making it suitable for sensitive eyes or frequent use. HA forms a protective hydrophilic layer that reduces friction and promotes corneal healing.
