Intra-articular Injections: Hyaluronic acid is injected directly into the joints, particularly the knees, to alleviate pain and improve joint function in individuals with osteoarthritis. This treatment is known as viscosupplementation. HA injections can provide lubrication to the joint, reduce inflammation, and improve mobility.

Cosmetic Use: In the field of aesthetics, hyaluronic acid is used as a dermal filler to reduce the appearance of wrinkles, fine lines, and to add volume to areas such as the cheeks and lips. The procedure is minimally invasive and provides immediate results with a low risk of complications.

Topical Treatments: Hyaluronic acid is a common ingredient in many skincare products, such as serums and moisturizers, due to its powerful hydrating properties. When applied topically, it helps the skin retain moisture, which can reduce dryness, improve elasticity, and give the skin a plumper, more youthful appearance.

Medical Applications: Hyaluronic acid is used in certain medical dressings and wound care products. Its ability to promote tissue regeneration and reduce inflammation makes it effective in treating wounds, burns, and ulcers.

Ophthalmic Surgery: HA is used in eye surgery, particularly during cataract removal, corneal transplantation, and repair of a detached retina. It helps maintain the shape of the eye, protects delicate tissues, and aids in healing.

Dental Use: Hyaluronic acid is also used in dentistry to promote the healing of gums and other tissues after surgical procedures, such as tooth extractions or periodontal treatments.
