Hyaluronic acid is a molecule naturally present in the skin and in various tissues of our body, including the eyes and joints .
Capable of retaining 1000 times its weight in water , hyaluronic acid plays an essential role in maintaining hydration , suppleness and firmness of the skin. Just like collagen and elastin, it helps form the skin's support structure, giving it a youthful, glowing appearance.
Unfortunately, the natural production of hyaluronic acid tends to decline with age and under the effect of external aggressions such as UV rays and pollution.
This drop in production can lead to a loss of elasticity , firmness and the appearance of fine lines and wrinkles . This phenomenon is often linked to age , but it can be accelerated by environmental factors and a stressful lifestyle .
