Eye Drop Grade Sodium Hyaluronate: Ideal For Eye Protection And Moisturizing
Sodium hyaluronate is a polysaccharide substance naturally found in human tissues and is known for its excellent moisturizing properties. In the field of ophthalmology, eye drop grade sodium hyaluronate is widely used in eye care and treatment due to its high purity and biocompatibility, especially in relieving dry eyes and promoting eye repair.
Eye drop grade sodium hyaluronate is a high-quality sodium hyaluronate specially developed for eye care products. Compared with medical grade sodium hyaluronate, it has higher purity, is gentler on the eyes, and is safer to use. Its molecular structure is extremely water-absorbent and can effectively capture and retain moisture, forming a moisturizing protective film on the eye surface to protect the eyes from external environmental stimulation.
