Eye Drop Grade Sodium Hyaluronate: A "Natural Moisturizing Factor" to Protect Eyes

Sodium hyaluronate is a polysaccharide naturally present in human connective tissue, with strong water absorption and moisturizing ability. It is the sodium salt form of hyaluronic acid, with stable molecular structure and high biocompatibility, and is widely used in medical, cosmetic and ophthalmology fields.

Eye drop grade sodium hyaluronate is a high-molecular natural moisturizing factor with high purity, low irritation and excellent biocompatibility. It is specially used in ophthalmic preparations and can form a lubricating, moisturizing and protective film on the ocular surface. It is used to relieve dry eyes, repair the cornea and improve the comfort and efficacy of eye drops.
