About Hyaluronic Acid
What is Hyaluronic Acid?
Hyaluronic acid (HA) is a carbohydrate, or more specifically, a mucopolysaccharide that occurs naturally throughout the human body and presents itself as a large high molecular weight molecule. The molecule comprises a repetitive sequence of two modified simple sugar called glucuronic acid and N acetyl glucosamine. These compounds are both negatively charged, and together they repel, producing an exceptionally long stretched out molecule (high molecular weight). HA molecules that are long and large have a high viscosity (lubrication) effect, which resists compression and allows our joints and skin to bear weight.
Its function in the body, amongst other things, is to lubricate movable parts of the body, such as joints and muscles. Its consistency and tissue-friendliness also allow it to be beneficial in skin-care products as an excellent moisturizer. Because HA is one of the most hydrophilic (water-loving) molecules in nature, with numerous benefits for the human body, it can be described as “nature’s moisturizer.” HA is one of the most researched substances in medicine today, particularly in eye surgery and orthopedics.

When Was Hyaluronic Acid Discovered?
HA was first discovered in 1934 by Karl Meyer and John Palmer, scientists at Columbia University, New York. Since then, researchers and scientists worldwide have been studying its properties and applications, and new information is continually being documented.
