Eye Drop Grade Hyaluronic Acid: A New Choice for Eye Care
Hyaluronic Acid (HA) is a polysaccharide naturally found in the human body and is widely distributed in skin, joints, eyes and other parts of the body. Its most remarkable feature is its ability to absorb and retain a large amount of moisture. Each molecule of hyaluronic acid can absorb hundreds of times its own weight in moisture, giving it extremely strong moisturizing ability.
Eye drop grade hyaluronic acid is a hyaluronic acid formula specially designed for the eyes, and its purity and safety meet medical standards. Unlike ordinary hyaluronic acid, eye drop grade hyaluronic acid needs to undergo strict filtration, purification and stability testing to ensure that it will not cause discomfort or allergic reactions when used on the eyes. For this reason, eye drop-grade hyaluronic acid is typically formulated without any harsh added ingredients, such as preservatives or other chemicals.
