Mary&May Niacinamide Vitamin C Mask is a Korean sheet mask set containing 30 individually packaged sheets, each with 13.52 fluid ounces of serum. This fragrance-free formula combines niacinamide and vitamin C to support a brighter and more even skin tone. Niacinamide works to improve the appearance of dark spots and uneven texture, while vitamin C provides antioxidant benefits that help protect against environmental stressors. The lightweight, watery serum absorbs quickly into the skin without leaving a sticky residue, making it suitable for daily use. The sheet mask material is designed to adhere closely to the face, allowing the serum to be absorbed effectively. This product is formulated without artificial fragrances, making it a suitable option for those with sensitive or reactive skin who prefer minimal ingredients. It is intended for individuals looking to address dullness and uneven pigmentation as part of a regular skincare routine. The generous quantity of 30 masks supports consistent application over time, which can contribute to gradual improvement in skin clarity and radiance. The mask is also suitable for combination, oily, or normal skin types, as its non-greasy formulation does not clog pores. To use, cleanse the face, apply the mask for 15–20 minutes, then remove and gently pat any remaining serum into the skin. This product is manufactured in Korea and follows standard quality controls for skincare items. It is not tested on animals. The packaging is straightforward and practical, ideal for those who prefer a no-fuss approach to skincare.
