It is a fundamental skin component. Thanks to its properties it gives to the skin the classical characteristic of elasticity and softness. Its dermal connective tissue concentration, however, tends to decrease with advancing age. The consistent use of hyaluronic acid can reactivate mature skin by stimulating cellular function and restoring to it elasticity and translucency. It also re-establishes the right rate of umidity by slowing down, in a phisiological way, the water evaporating process. This wetting action also influence the mechanical properties of keratin which becomes more flexible and elastic. Besides, it also has a prolonged film forming moisturising action which is effective even in wide surfaces, maintaining the right wetness on the skin even in case of hot temperature or particularly dry climate. Directions of use: apply on clean skin and massage until completely absorbed. Active principles: Hyaluronic Acid.
