The **Cathy Doll Asta-Xanthin Serum Mask Sheet** delivers powerful age-defying care in one quick, relaxing step. Its hero is Astaxanthin — a xanthophyll carotenoid recognized as one of the world’s most potent antioxidants — prized for fighting free-radical and environmental damage, softening the look of fine lines, soothing irritation, and strengthening skin from within.

It’s combined with Red Algae Extract (Kouso Ekisu) for firming, resilience-boosting benefits, and Tomato Extract for natural brightness and extra antioxidant protection against pollution and UV stress. Glyceryl Caprylate helps lock in moisture, so skin is left smooth, plump, and refreshed after every use. The sheet itself is crafted from ultra-soft 100% plant-derived fiber that adheres gently to the contours of the face for comfortable, irritation-free wear and maximum serum absorption.

The result is firmer, smoother, more protected, healthy-glowing skin. Formulated without alcohol, parabens, colorants, hydroquinone, and mineral oil — safe for all skin types, including sensitive skin.

How to Use: After cleansing and toning, unfold the mask and apply it evenly across the face, smoothing out air bubbles. Leave on for 15–20 minutes, then remove. Gently pat the remaining serum into the skin until absorbed — apply any excess to the neck, arms, or hands. No rinsing required. Use 2–3 times a week to maintain brightness and a smooth, glowing finish.

Key Ingredients: Astaxanthin, Red Algae Extract (Kouso Ekisu), Tomato (Solanum Lycopersicum) Extract, Glyceryl Caprylate, with hydrating and skin-conditioning agents.
