What Is Hyaluronic Acid
Hyaluronic acid is a natural polysaccharide found in skin, connective tissue, and eyes. It binds water to support hydration and cushioning. It is widely used in skincare, medical injections, and eye surgery.
Types of Hyaluronic Acid
Products differ by molecular weight. High molecular weight hyaluronic acid forms a surface film for immediate moisture. Low molecular weight versions penetrate deeper layers. Some formulations combine multiple weights for layered hydration.
How to Choose the Best Form
For topical skincare, look for hyaluronic acid near the top of the ingredient list. For joint support or dermal fillers, use clinically reviewed products and licensed professionals. Check storage conditions and avoid products with excessive fragrance or irritants.
