WHAT ARE THE INDICATIONS FOR HYALURONIC ACID INJECTIONS OUTSIDE AESTHETIC MEDICINE ?

Dernière mise à jour : 22 May 2026

Hyaluronic acid is now mainly associated with aesthetic medicine and the treatment of facial ageing. Yet this molecule has many medical applications well beyond aesthetics. Naturally present in the body, it plays an essential role in tissue hydration, joint lubrication, wound healing and cellular protection. Thanks to its exceptional biological properties, hyaluronic acid has been used for many years in several medical specialties such as rheumatology, ophthalmology, sports medicine, reconstructive surgery and gynaecology. Today, hyaluronic acid is a genuine therapeutic tool for many medical conditions.

The natural role of hyaluronic acid in the body

Hyaluronic acid is a molecule naturally produced by the human body. It is present in many tissues, particularly the skin, joints, cartilage, eyes and certain mucous membranes. Its main property is its exceptional ability to retain water. A single molecule can bind up to a thousand times its weight in water, enabling it to maintain tissue hydration and suppleness. In the joints, hyaluronic acid contributes to the lubricating properties of synovial fluid. In the skin, it helps maintain dermal hydration and density. In the eyes, it protects the ocular surface and stabilises the tear film. With age or because of certain diseases, the quantity of hyaluronic acid gradually decreases. This loss explains some of its current medical indications.

Hyaluronic acid injections for osteoarthritis

One of the main medical uses of hyaluronic acid is the treatment of osteoarthritis. In a healthy joint, synovial fluid naturally contains a high concentration of hyaluronic acid. This substance acts as a lubricant and mechanical shock absorber that protects cartilage surfaces. With osteoarthritis, joint fluid gradually becomes less viscous and less protective. Cartilage wears down further, friction increases and pain develops. Intra-articular hyaluronic acid injections, known as viscosupplementation, aim to improve synovial fluid quality to reduce pain and improve joint mobility. However, results depend on the stage of osteoarthritis, the condition of the cartilage and the patient's profile.

Hyaluronic acid in sports medicine

In sports medicine, hyaluronic acid is also used in certain specific situations. For athletes, some chronic joint pain or cartilage injuries may benefit from hyaluronic acid injections to improve functional comfort and limit inflammation associated with repeated mechanical stress. Its excellent local tolerance and lubricating properties explain its value in certain conditions related to sporting activity.

Applications of hyaluronic acid in ophthalmology

Ophthalmology is another major field of medical use for hyaluronic acid. This molecule is widely used in dry eye treatments. Thanks to its strong hydrating capacity, it stabilises the tear film and improves comfort on the eye's surface. Artificial tears containing hyaluronic acid are frequently prescribed for patients with chronic dry eye, irritation, burning sensations or after certain eye operations. Hyaluronic acid is also used during certain ophthalmic operations, particularly cataract surgery or some intraocular procedures. It then protects ocular structures and limits surgical trauma.

Indications in reconstructive surgery

The hydrating and wound-healing properties of hyaluronic acid also make it particularly valuable in reparative and reconstructive surgery. Certain specific formulations are used to improve healing, optimise tissue repair or soften certain scars. Hyaluronic acid can also be used to treat some chronic wounds, burns or skin tissue loss. Its role in maintaining a moist environment favourable to tissue repair explains its value in many complex medical situations.

Hyaluronic acid in gynaecology

Hyaluronic acid also has several applications in gynaecology and intimate medicine. With age, menopause or certain hormonal treatments, the vaginal mucous membranes may become drier, more fragile and more uncomfortable. Hyaluronic acid is used to treat vaginal dryness and G-spot augmentation.

The role of hyaluronic acid in wound healing

Hyaluronic acid plays an essential role in the body's natural tissue repair mechanisms. Certain medical formulations are used to treat chronic wounds, ulcers, burns or delayed healing. The aim is to promote a local environment favourable to tissue repair, maintain good hydration and limit certain inflammatory processes. This use is particularly valuable for older or diabetic patients, for whom healing may be more difficult.

ENT applications of hyaluronic acid

Hyaluronic acid is also used in certain ENT specialties. It is found in some nasal sprays or treatments intended to improve the hydration of irritated mucous membranes. Its protective and hydrating properties reduce dryness and promote tissue repair after certain surgical procedures or chronic inflammation.

Medical dermatology indications

Hyaluronic acid also has indications in medical dermatology. Certain formulations are used to improve hydration in fragile skin, promote wound healing or support the management of some inflammatory skin conditions. Its role in tissue repair and protection explains its growing value in several areas of modern dermatology.

Why is hyaluronic acid so widely used in medicine?

The medical success of hyaluronic acid relies on several major biological characteristics. This molecule has excellent tolerance, a strong hydrating capacity and a protective role in many tissues. As it is naturally present in the body, allergic reactions remain rare. Its absorbable nature is also an important advantage in medicine. This versatility explains why hyaluronic acid is now used in so many different medical specialties.
