Humectant and lubricating ophthalmic solution based on hyaluronic acid sodium salt 0.2%.
Thanks to its chemical-physical properties, hyaluronic acid adheres perfectly to the corneal surface and thus allows a profitable hydration and lubrication. Hyaluronic acid is of biotechnological origin and of high molecular weight such as to give it high adhesion power and long residence time in contact with the cornea. It represents the ideal remedy in case of dryness due to varifactors such as stress, dust, fumes, prolonged exposure to sunlight, continuous work at video terminals, use of contact lenses.
