Hyaluronic acid, a substance naturally present in the human body, is increasingly recognized for its multiple applications in medicine. Although it has gained notoriety in the world of aesthetics, mainly for its moisturizing and skin-filling properties, its use goes far beyond dermatological clinics. Today, it is used in skin treatments and even for infiltration in joints, relieving chronic pain, such as in the case of the knee. The versatility of this compound positions it as one of the great bets of medicine for the future.
In dermatology, hyaluronic acid is widely used to treat signs of aging, such as wrinkles and deep grooves. The compound acts as a potent moisturizer, attracting and retaining water, which gives the skin a more youthful and revitalized appearance. "Hyaluronic acid is a molecule that already exists naturally in our skin. Over time, its production decreases, and that is what causes dryness and loss of volume," explains dermatologist Karina Mazzini.
In aesthetic treatments, hyaluronic acid can be injected into different areas of the face to fill in wrinkles, grooves, and even scars, providing immediate results and a more natural appearance. Another benefit is its biocompatibility, which reduces the chances of rejection or adverse reactions.
The use of hyaluronic acid has revolutionized the treatment of joint pain, especially in patients with knee osteoarthritis. The intra-articular infiltration of the compound aims to increase the lubrication of the joint, reducing friction between the bones and, consequently, pain and inflammation. Chronic pain specialist neurologist Ramon D'Ângelo Dias explains: “the procedure has shown excellent results in pain control for patients with knee osteoarthritis. It works by restoring the viscoelastic properties of synovial fluid, which improves mobility and reduces discomfort. This approach can be an important relief, especially for those who cannot or do not wish to undergo immediate surgery.”
The great appeal of hyaluronic acid in its various applications lies precisely in its biocompatibility, meaning it is a substance that the human body recognizes and absorbs easily. This reduces the risks of serious complications, such as rejections or allergic reactions. Furthermore, the application procedure, whether on the skin, joints, or sweat glands, is minimally invasive and has a quick recovery time.
However, it is important to remember that, like any medical treatment, the use of hyaluronic acid requires professional evaluation. "As safe as hyaluronic acid is, it should be applied by specialized doctors to ensure effective results and avoid possible complications," warns doctor Natália Nascif.
