Nivea's Hyaluron Cellular Filler Contour 10-Minute Sheet Mask is a biodegradable tissue mask infused with a potent blend of Hyaluronic Acid and a Collagen Activating Booster. This innovative mask is designed to fill in wrinkles and redefine facial contours in just 10 minutes. Its unique formula helps rejuvenate the skin, encouraging cell activity that boosts natural collagen production. Each mask contains the equivalent of half a serum, delivering intense hydration and promoting firmer, more voluminous skin for an immediate triple effect. It is recommended for use twice a week and offers an extra refreshing experience when chilled in the refrigerator prior to application. To use, start with clean, dry facial skin. Position the white side of the mask against your skin while keeping the blue side on the outside. Adjust the mask for a snug fit, then carefully remove the blue protective layer to activate the ingredients. Allow the mask to work its magic for 10 minutes. When finished, gently lift the mask from the ends and use a cotton pad to wipe away any remaining product.
