The role of hyaluronic acid in the skin

Hyaluronic acid (HA) is found throughout the body. In the skin, HA helps support biomechanical properties and it plays an important role in maintaining moisture.

The declining lifespan of hyaluronic acid

Hyaluronic acid (HA) has a short lifecycle in skin, with 30-50% degrading every 24 hours. With age, the skin's ability to produce HA decreases. HA production starts to decline in the 20s and this decline accelerates in the 40s. Decreased production and rapid degradation of HA contribute to the signs of aging, including decreased firmness, less facial plumpness, and rough texture.
