Masque Expert Bio Cellulose: Intensive Hydrating & Anti-Age Sheet Mask 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. Key Benefits How to Use Key Ingredients FAQ Intensive, Long-Lasting Hydration: Biocellulose technology delivers actives deep into the skin, providing sustained hydration that outlasts conventional sheet masks. Plumps & Restores Volume: Collagen and Hyaluronic Acid work together to visibly plump, firm, and restore a more youthful-looking appearance. Smooths Fine Lines: Sustained hydration from Hyaluronic Acid reduces the depth of fine dehydration lines and early wrinkles.

Collagen: Supports fibroblast activity to stimulate collagen production, restoring skin volume and tonicity. Helps visibly improve the appearance of wrinkles. Other actives: Aloe vera, glycerin. What makes biocellulose different from a standard sheet mask? Biocellulose is a naturally derived material produced through bacterial fermentation. Its ultra-fine fiber network creates a second-skin fit that adheres closely to facial contours, minimizing air exposure and maximizing the depth and efficiency of active ingredient delivery — far beyond what a standard cotton or paper sheet mask achieves. Can I use it after professional treatments? Yes — its soothing, hydrating profile makes it well-suited for use after professional facials, peels, or laser treatments to support recovery and restore comfort. Consult your esthetician for timing specific to your treatment. How often should I use it? 1–2 times per week for maintenance. During periods of particular stress, dryness, or after professional treatments, it can be used more frequently. Do I need to rinse after removing the mask? No. Gently blot away any remaining serum with a tissue and follow immediately with your Mansard cream to seal in the treatment. Rinsing would remove the active residue that continues working after mask removal.
