Hyaluronic acid, also known as hyaluronan or hyaluronate, is a naturally occurring substance found in the human body, particularly in connective tissues, synovial fluid, and the extracellular matrix of skin. It is a glycosaminoglycan, a type of long, unbranched polysaccharide composed of repeating disaccharide units of glucuronic acid and N-acetylglucosamine. Hyaluronic acid plays a crucial role in maintaining skin hydration, joint lubrication, and tissue repair.

In the skin, hyaluronic acid binds large amounts of water, helping to maintain moisture levels and contribute to skin elasticity and plumpness. As people age, the natural production of hyaluronic acid decreases, leading to reduced skin hydration and the formation of wrinkles. This decline has prompted the use of hyaluronic acid in cosmetic and dermatological applications, such as fillers and moisturizers, to restore volume and hydration to the skin.

Beyond skincare, hyaluronic acid is widely used in medical treatments. It serves as a lubricant in joints, reducing friction and cushioning bones during movement, which is particularly beneficial for individuals with osteoarthritis. In ophthalmology, hyaluronic acid is used in eye surgeries, such as cataract procedures, to maintain intraocular pressure and protect tissues. It is also employed in wound healing and tissue engineering due to its biocompatibility and ability to promote cell growth.

Hyaluronic acid can be derived from sources such as rooster combs, bacterial fermentation, or synthesized chemically. Topical products containing hyaluronic acid are available over the counter, while injectable forms require professional administration. The substance is generally considered safe, though allergic reactions or irritation may occur in some individuals. Research continues to explore additional therapeutic applications, including potential uses in anti-inflammatory treatments and regenerative medicine.
