Tonymoly I'M Makgeolli Mask Sheet is a skin-purifying facial mask that utilizes the beneficial properties of makgeolli, a traditional Korean rice wine. This sheet mask helps cleanse and purify the skin while providing nourishing hydration through its essence-soaked three-layer pulp sheet. Each mask contains 21g (0.74 oz) of essence and is designed to be used for 20-30 minutes. Makgeolli contains natural enzymes and amino acids that help brighten and clarify the skin. For best results, apply to clean, dry skin and gently pat remaining essence into skin after removing the sheet mask.
