Eye Drop Grade Hyaluronic Acid: A New Choice for Eye Care
Pure hyaluronic acid powder is a powder product with hyaluronic acid (HA) as the main ingredient. Hyaluronic acid is a polysaccharide naturally found in skin, joints and connective tissues. It has strong moisturizing ability and can help the skin retain moisture and increase skin elasticity.
Eye drop grade hyaluronic acid refers to high-purity hyaluronic acid specially prepared for eye use. It is usually used to relieve eye dryness and fatigue and help repair and moisturize eye tissue. What is special about this type of hyaluronic acid is that it needs to meet higher safety standards to ensure its purity, stability and biocompatibility for long-term eye contact.
