Hyaluronic acid is a polysaccharide (carbohydrate chain) and a natural component of the body (to be found in dermis, joints, discs, kneecaps). It is biotechnologically extracted from bacteria cultures. With increasing age the deposits of hyaluronan in the body decrease which leads to missing synovial fluid or to wrinkling. Hyaluronic acid effectively binds moisture and prevents the skins own water from vaporising too rapidly (the transepidermal water loss is decreased and hydration of the skin is increased). Thus dry skin is replenished with extra moisture, the skin appears more smooth and well-tended.
