Hyaluronic acid has a variety of uses. Many people take it as a supplement, but it’s also used in topical serums, eye drops and injections.
Hyaluronic acid, also known as hyaluronan, is a clear, gooey substance that is naturally produced by your body.
The largest amounts of it are found in your skin, connective tissue and eyes.
Its main function is to retain water to keep your tissues well lubricated and moist.
Here are 7 scientifically backed benefits of taking hyaluronic acid.
1. It make your skin Healthier, More Supple Skin
Roughly half of the hyaluronic acid in your body is present in your skin, where it binds to water to help retain moisture.
However, the natural aging process and exposure to things like ultraviolet radiation from the sun, tobacco smoke and pollution can decrease its amounts in the skin.

Taking hyaluronic acid supplements may prevent this decline by giving your body extra amounts to incorporate into the skin.
Doses of 120–240 mg per day for at least one month have been shown to significantly increase skin moisture and reduce dry skin in adults.
2. It Relieve Joint Pain by Keeping Bones Well Lubricated
Hyaluronic acid is also found in the joints and it keeps the space between your bones well lubricated.
When the joints are lubricated, the bones are less likely to grind against each other and cause uncomfortable pain.
Hyaluronic acid supplements are very helpful for people suffering from osteoarthritis, a type of degenerative joint disease caused by wear and tear on the joints over time.
Taking 80–200 mg daily for at least two months has been shown to significantly reduce knee pain in people with osteoarthritis, especially those between the ages of 40 and 70 years old.
Hyaluronic acid can also be injected directly into the joints for pain relief. However, an analysis of over 12,000 adults found only a modest reduction in pain and a greater risk of adverse effects.
3. It can Relieve Dry Eye and Discomfort
Approximately 1 out of 7 older adults suffer from symptoms of dry eye due to reduced tear production or tears evaporating too quickly.
Since hyaluronic acid is excellent at retaining moisture, it’s often used to treat dry eye.
