Eye Drop Grade Hyaluronic Acid: The “Natural Moisturizer” For Eye Care
Hyaluronic Acid (HA) is a polysaccharide naturally present in the human body, especially abundant in the skin, joints and eyes. It has extremely strong water retention capacity and can absorb hundreds of times its own weight in water, so it is known as a "natural moisturizing factor".
Eye drop grade hyaluronic acid is specially processed high-purity, sterile hyaluronic acid specifically designed for eye care. It has a moderate molecular weight and can form a stable moisturizing film on the surface of the eyeball without increasing the viscosity of the liquid, ensuring comfort during use.
Samples: 5 grams of free samples are available for costomer to test and eveluation.
