Presentation: Tube | 50 ml | 1.75 fl. oz. Hyaluronic Acid, the main active ingredient in MesoAge®, is a natural component of the skin that retains water molecules and gradually fills in wrinkles. Over time, the natural levels of Hyaluronic Acid drop dramatically, causing loss of elasticity, deep wrinkles, and dehydration in the skin. MesoAge® provides the amounts of Hyaluronic Acid necessary to maintain the structural integrity of the dermal collagen matrix. The botanical assets it contains increase the properties of Hyaluronic Acid obtaining an instant firming effect. In addition, the anti-irritant polysaccharides of MesoAge® protect against environmental damage building a non-occlusive protective film.
