3. Medical grade (Eye drops) hyaluronic acid functions and uses


Hyaluronic acid can significantly improve the bioavailability of drugs through its physical thickening, membrane affinity, and combination with drugs. Its advantages are unmatched by other polymer materials. It can also be modified by cross-linking and restructuring to prolong the retention time in the eye and further increase the bioavailability of the drug.



Eye drops grade hyaluronic acid is used in eye drops, contact lens solutions, eye lotions, lubricants, cell culture and etc.
