Missha Mascure Hydra Solution Sheet Mask features hyaluronic acid as its key ingredient to provide deep hydration and moisturization. The mask uses PT cell sheets with high water retention to effectively deliver nourishing ingredients while being gentle enough for sensitive skin. To use: After cleansing, apply toner then place the mask sheet evenly over your face. Leave on for 20-30 minutes. Remove the mask and gently pat any remaining essence into your skin until fully absorbed. The hypoallergenic formula contains ingredients like hyaluronic acid, bergamot oil, sage oil, and ceramides to hydrate and soothe the skin while strengthening its moisture barrier.
