Consequence of aging, the natural rate of hyaluronic Acid in skin diminishes and it loses its volume. The skin-epidermis junction sags and wrinkles appear. Immediate visible effect: Thanks to its filling action, Hyaluronic Acid immediately gives volume to the skin, and thus visibly reduces the wrinkles. It fills all the wrinkles, even the deepest ones: Eucerin Hyaluron-Filler Night Care contains Saponin, a bioactive ingredient which stimulates the natural synthesis of the Hyaluronic Acid. The weakened fabric under the wrinkles is reinforced. The wrinkles, even the deepest, are filled up. The rich cream makes the skin pleasantly silky.
