Molecular Structure



Hyaluronic Acid (Sodium Hyaluronate) is a substance that is naturally present in the human body. It is found in the highest concentrations in fluids in the eyes and joints.

Some people take Hyaluronic Acid to support joint health.

For cosmetic use, Hyaluronic Acid is also used in plastic surgery. Some people apply Hyaluronic Acid to the skin for healing wounds, burns, skin ulcers, and as a moisturizer (humectant).

Hyaluronic Acid is also used for anti-aging formulations due to its ability to help with skin elasticity.
