Deeply replenish your thirsty complexion with the Institut Esthederm Intensive Hyaluronic Mask, an intense formula for severely dehydrated skin. Instantly quenching, this mask is created with hyaluronic acid at its heart, a molecule that acts as the skin's water reserve. This mask works to redensify skin tissue by filling it with water, giving skin a plumper, smoother and more luminous appearance. It's your ticket to a more radiant complexion. At the heart of the formula is a trio of three different forms of hyaluronic acid, which penetrate the skin at different layers to provide both immediate and long-lasting hydration. Wrinkles and fine lines are filled in from the inside out, giving a more youthful appearance. Apply a thick layer to the face, neck and décolletage and leave for 15 to 20 minutes. Use 2 to 3 times a week.
