Cathy Doll Spot Light Serum Mask Sheet

The **Cathy Doll Spot Light Serum Mask Sheet** is a brightening serum sheet mask designed to put the spotlight on dark spots and uneven tone. Soaked in a concentrated brightening serum, it delivers a fast, radiance-boosting treatment that leaves skin clearer, brighter, and more even after a single use.

The serum is led by brightening Vitamin C and Niacinamide (Vitamin B3), which work together to fade the look of dark spots, reduce dullness, and even out skin tone, supported by Arbutin to gently target pigmentation. Hydrating Hyaluronic Acid floods the skin with moisture so it stays plump, smooth, and comfortable while it brightens. The soft, close-fitting sheet helps the serum absorb deeply for maximum effect.

The result is brighter, smoother, more even-toned, glowing skin — perfect as a weekly treat or a quick glow boost before a special occasion. Suitable for all skin types.

How to Use: After cleansing and toning, unfold the mask and apply it evenly across the face, smoothing out any air bubbles. Leave on for 15–20 minutes, then remove. Gently pat the remaining serum into the skin (and neck) until absorbed — no need to rinse. Follow with moisturizer. Use 2–3 times a week.

Key Ingredients: Vitamin C (Ascorbic Acid / 3-O-Ethyl Ascorbic Acid), Niacinamide (Vitamin B3), Arbutin, Hyaluronic Acid, Glycerin.
