Hyaluronic acid is an endogenous substance. Chemically speaking, hyaluronic acid is a chain of sugar molecules with the property of binding water. In anti-aging, hyaluronic acid is used against wrinkles because it can bind about 6000 times more water than its own weight, so 1 gram of hyaluronic acid can bind 6 litres of water. In the human body, most hyaluronic acid is stored in the skin, where it holds the cells together. It is also found in joints and in the eyes.

From the age of 25 onwards, the body’s own production of hyaluronic acid decreases. At the age of 60, only 10% of the initial hyaluronic acid level can be detected in the body.
