Hyaluronic acid generally functions to moisturize, fight aging, provide filling, lubricate joints, and protect the eyes.

Hyaluronic acid is a natural moisturizing component that can absorb and retain large amounts of water, creating a hydrating effect and providing moisture for the skin, maintaining its elasticity and luster. This helps improve dry, dehydrated, rough, or sallow skin, making the skin smoother and more delicate.

With aging, the body's hyaluronic acid levels gradually decrease. Supplementing hyaluronic acid can help improve dry skin and fine lines, delaying the skin aging process. Hyaluronic acid can also be used to enhance facial contours, such as raising the nose bridge, plumping the lips, and filling the temples. With precise injection techniques, more defined and natural facial contours can be achieved.

In the joints, hyaluronic acid acts as a lubricant, reducing friction between bones. For patients with arthritis, hyaluronic acid injections can relieve pain and increase joint mobility. Injecting hyaluronic acid into the eye area can fill depressed tear troughs and reduce the appearance of dark circles. During eye surgeries, hyaluronic acid is often used as a filling agent to protect the retina and cornea and prevent postoperative complications.

It is recommended to visit a reputable hospital and follow medical advice to select high-quality, approved hyaluronic acid products.
