Hyaluronic acid is an important component of articular cartilage, where it is present as a coat around each cell.

What Does Hyaluronic Acid Do?

  • Hyaluronic acid is also a major component of skin, where it is involved in tissue repair. When skin is exposed to excessive UVB rays, it becomes inflamed (sunburn) and the cells in the dermis stop producing as much hyaluronan, and increase the rate of its degradation. Hyaluronan degradation products then accumulate in the skin after UV exposure.
  • Hyaluronic acid provides lubrication to the connective tissues of our joints and skin and is an important part of our skin’s overall health.
  • Hyaluronic acid is  found in the joints, where it keeps the space between your bones well lubricated
  • Hyaluronic acid is present in many areas of  body including eyes and connective tissue, but much of it is in your skin, which accounts for 50% of your body’s total hyaluronic acid level.
  • Hyaluronic acid is abundant in extracellular matrices, hyaluronan also contributes to tissue hydrodynamics, movement and proliferation of cells, and participates in a number of cell surface receptor interactions.

The human body degrades about one-third of its Hyaluronic Acid stores each day. Normally, this Hyaluronic Acid is simply replaced with new Hyaluronic Acid that the body synthesizes, but beginning as early as young adulthood, our production of HA begins to decrease, and this decrease accelerates with age. By middle age,
our bodies can no longer make up the amount of HA they lose, and the telltale signs of aging become apparent. Joints lose their ability to maintain proper cushion, and there is a need to support healthy movement. The collagen in our skin loses its moisture, and the skin sags and wrinkles.


Hyaluronic acid has been FDA approved to treat osteoarthritis of the knee via injecting it into the joint, although some studies show a lack of evidence for significant benefit and potentially severe adverse effects. Dry, scaly skin such as that caused by atopic dermatitis may be treated with skin lotion containing sodium hyaluronate as its active ingredient.

The FDA has approved the use of hyaluronic acid during certain eye surgeries including cataract removal, corneal transplantation, and repair of a detached retinaand other eye injuries. It is injected into the eye during the procedure to help replace natural fluids.

Hyaluronic acid is also used as a lip filler in plastic surgery.

Some people apply hyaluronic acid to the skin for healing wounds, burns, skin ulcers, and as a moisturizer.

There is also a lot of interest in using hyaluronic acid to prevent the effects of aging. In fact, hyaluronic acid has been promoted as a “fountain of youth.” However, there is no evidence to support the claim that taking it by mouth or applying it to the skin can prevent changes associated with aging.
