The **Cathy Doll Whitamin C Serum Mask Sheet** delivers a double dose of care — brightening and anti-aging — in one quick, relaxing step. Soaked in a Vitamin C–rich serum, it works to fade dullness, dark spots, and uneven tone, revealing a brighter, clearer, more radiant complexion, while delivering antioxidant protection against environmental damage.

What sets it apart is its rich blend of 8 peptide ingredients, which work to make deep wrinkles and fine lines on the face appear more shallow and smooth — adding a youthful, firming benefit on top of the Vitamin C glow. The serum hydrates and plumps as it absorbs, leaving skin soft, supple, and luminous.

The sheet itself is crafted from soft, close-fitting fiber that adheres seamlessly to the contours of the face, helping the serum penetrate deeply for maximum effect. The result is brighter, smoother, more even-toned, youthful-looking skin. 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. Use 2–3 times a week for best results.

Key Ingredients: Vitamin C (Ascorbic Acid / 3-O-Ethyl Ascorbic Acid), 8 Peptide Complex, Niacinamide, Hyaluronic Acid, with hydrating and skin-conditioning agents.
