Roughly half of the hyaluronic acid in your body is present in your skin, where it binds to water to help retain moisture. Hydrated skin also reduces the appearance of wrinkles, which may explain why several studies show that supplementing with Hyaluronic Acid can make the skin appear smoother and improve skin hydration, texture, and elasticity. It can help your skin look and feel more supple.

Hyaluronic Acid also plays a key role in wound healing. It’s naturally present in the skin, but its concentrations increase when there is damage in need of repair. Applying Hyaluronic Acid directly to an open wound can help speed up the recovery process. It’s unknown whether supplementing with it could have the same effect.

Hyaluronic Acid is also found in the joints, where 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.

Hyaluronic Acid is naturally found in the eyes and often an ingredient in eye drops to relieve dry eye symptoms. It’s unknown whether supplementing with it could have the same effects.

Animal and test-tube research suggests that high doses of Hyaluronic Acid may help prevent bone loss, but no research has been conducted in humans.

New research shows that Hyaluronic Acid supplements may help reduce symptoms of acid reflux.
