This face sheet mask is a  gel-based mask soaked in a nutrient-rich serum, designed to deliver concentrated skincare benefits to the face. It is usually made of materials like cotton, microfiber, hydrogel, or bio-cellulose and has cutouts for the eyes, nose, and mouth. The mask is placed on a cleansed face and left for about 15–20 minutes to allow the skin to absorb the active ingredients. Sheet masks are known for their hydrating, brightening, anti-aging, and soothing effects, making them a popular part of modern skincare routines.
