Hyaluronic Acid & Aging Process
Hyaluronic Acid in Skin
Nearly 50 percent of total HA (Hyaluronic Acid) found in the body is in the skin. HA helps skin cells survive longer, thickening the epidermis and preventing the buildup of dead skin in that layer. It may also protect the epidermis by scavenging free radicals generated by ultraviolet (UV) radiation exposure.
Collagen is fibrous protein that consists cell structure. Between collagen are filled with water and HA, forming a structure like reinforced concrete walls in a cell. Collagen keeps cartilage elasticity, while HA holds moisture.
In addition, Hyaluronic Acid has a role to nourish collagen. In other words, Hyaluronic Acid works as a go-between of collagen and water. Consequently, when HA runs short, cells can no longer hold enough water and collagen itself degenerates, leading to loss of skin elasticity.

Hyaluronic Acid Depletion by Aging Process
Aging cause a constant decrease in the amount of Hyaluronic Acid. Suppose a baby has an Hyaluronic Acid level of 100, one in his/her sixties has a level of 25. Hyaluronic Acid by nature is produced in a human body, but it depletes as one grows older. This is because synthesis of Hyaluronic Acid takes a complex process and metabolic power of cells gradually degrades.
