This Vitamin C-powered sheet mask is designed to bring instant radiance while helping defend your skin from daily environmental stressors. Made from bio-cellulose (a naturally derived material originally used for wound healing), this ultra-adherent mask hugs your face like a second skin, allowing key ingredients to deeply penetrate without slipping or drying out.
✨ What You'll Love:
• Visibly brightens dull, uneven skin tone
• Defends against UV-induced skin damage and photo-aging
• Ultra-cling bio-cellulose mask ensures maximum absorption and no mess
🌿 Key Ingredients:
• Vitamin C (Ascorbic Acid) – Helps improve radiance, reduce dark spots, and support collagen production
• Glycerin – Delivers lasting hydration and plumps fine lines
• Betaine – Boosts skin barrier function and softness
How to Use:
After cleansing and toning, apply the mask to clean, dry skin. Smooth gently to fit the contours of your face. Leave on for 20–30 minutes. Remove and pat in the remaining essence until fully absorbed. No rinsing required.
