3W Clinic's Fresh Collagen Mask Sheet is a Korean cotton sheet mask soaked in a collagen-enriched essence that helps soothe and moisturize skin while supporting a smoother, more supple look, aimed at skin that has lost some of its elasticity. The essence also contains hydrating ingredients like glycerin and hyaluronate to support overall moisture levels. Suitable for most skin types as an occasional pampering treatment. After cleansing, apply the sheet evenly over the face avoiding eyes and lips, leave on for 15-20 minutes, then remove and gently pat in the leftover essence rather than rinsing off.
