Fundamental component of the derma. Thanks to its properties it gives to the skin the classical characteristic of elasticity and softness. Its concentration inside the cutaneous connective tissue, however, tends to decrease with the advancing of the age. The constant use of hyaluronic acid can reactivate mature skin by stimulating the cellular function and by restoring to the skin the compactness and the lost lucidity. 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 filmogenic moisturising action which is effective even on wide surfaces, maintaining the right wetness on the skin even in case of hot temperature or particularly dry climate. Directions for use: apply on cleansed skin and massage until completely absorbed. Active principles: Hyaluronic Acid, Plant Glycerine, Sorbitol.
