Virbac Regefluid artificial tears 10ml Hyaluronic acid is a mucopolysaccharide with viscoelastic properties, a natural component of the mucin layer of the precorneal tear film. The hyaluronic acid contained in REGEFLUID ensures good adhesion of the tear fluid (hydrophilic) to the surface of the cornea (hydrophobic), allowing the formation of a stable tear film on the ocular surface. The patented compound of amino acids, electrolytes, trace elements and vitamins closely resembles the composition of the natural tear film, creating an ideal environment for the nutrition and regeneration of corneal cells. If applying another ocular therapy topically, an application interval of at least 5 minutes must be respected.
