When people hear “hyaluronic acid,” they often think of moisturizing serums or anti-aging creams, or even cosmetic filler injections. But this remarkable ingredient does much more than just keep your skin hydrated. In fact, in the industry, we often refer to hyaluronic acid as sodium hyaluronate, which is just a different name for the same ingredient. Today, sodium hyaluronate has become a powerful tool in modern medicine—from relieving joint pain to treating eye diseases to speeding up wound healing.

Let’s take a deeper look at how this seemingly ordinary molecule works behind the scenes.

What is hyaluronic acid?

Hyaluronic acid is a natural substance found in the human body, especially in the skin, eyes, and joints. It has a unique ability to hold onto water—up to 1,000 times its weight—which is essential for keeping tissues moist and healthy.

In skincare and medicine, hyaluronic acid is often used in its salt form, sodium hyaluronate. Again, don’t worry—it’s essentially the same ingredient. Sodium hyaluronate just dissolves more easily in water and is more stable in formulas. In fact, almost every hyaluronic acid product on the market comes in this form.

How is it used medically?

Next, we're referring to sodium hyaluronate, which is hyaluronic acid, so keep that in mind.

Sodium hyaluronate is known for its moisturizing, lubricating, and repairing properties. Since it occurs naturally in the human body, it's also very safe and well-tolerated, making it ideal for medical use.

Here's how it's currently used:

1. Joint injections to relieve arthritis

For people with osteoarthritis, the cartilage in the joints wears away, causing pain and stiffness. Doctors can inject sodium hyaluronate directly into the joint (usually the knee) to act as a lubricant and cushioning agent, helping to relieve pain and improve mobility. It's like adding a new shock-absorbing layer to your joints.

2. Dry eye treatment and eye surgery

Sodium hyaluronate is widely used in eye drops for dry eye treatment, helping to keep the surface of the eye moist and protected. It's also used in eye surgeries (such as cataract surgery) to protect delicate eye tissue and promote healing.

3. Wound Healing and Burn Care

In creams, gels, and wound dressings, sodium hyaluronate helps speed healing, reduce inflammation, and keep the wound environment moist—critical for proper wound recovery. It’s especially effective for chronic wounds, such as diabetic ulcers or burns.

4. Nasal and Throat Sprays

Used in nasal sprays and throat products, sodium hyaluronate can soothe dry or irritated mucous membranes, whether caused by allergies, disease, or dry air.

Why is it so useful?

Moisturizing: It draws moisture into tissues, keeping them soft and flexible.

Protecting: It forms a gentle barrier over damaged or sensitive areas.

Healing: It helps new cells grow and reduces inflammation.

Compatibility: Because it occurs naturally in the body, it rarely causes side effects.

Looking Ahead

Scientists are still exploring new uses for sodium hyaluronate. Researchers are working on drug delivery systems, where the molecule can help deliver drugs deeper into tissues. Others are exploring inhalable forms for lung disease or advanced wound healing technologies.

Final Thoughts

Sodium hyaluronate may not make the headlines like vaccines or antibiotics, but it quietly improves lives every day—helping people move more comfortably, see better, and heal faster. From joints to eyes to skin, it truly is the unsung hero of modern healthcare.
