Laboratoires Mansard Masque Expert Bio Cellulose is an intensive hydrating and anti-aging sheet mask that uses a unique biocellulose carrier to deliver a high concentration of Collagen, Glucuronic Acid, and Hyaluronic Acid directly into the skin. The biocellulose texture forms a second-skin fit that ensures optimal penetration of active ingredients, effectively relieving sensations of stinging and tightness while leaving the skin smoother, plumper, and deeply moisturized. Suitable for any skin type.
Follow with the recommended Mansard cream to seal in the treatment. Use 1–2 times per week or as needed for intensive hydration.
