Dermask Ultrajet Porecting Solution combines cutting-edge essence and sheet technologies to effectively purify and detoxify skin. The ultra charcoal sheet wraps skin with a detoxifying and purifying effect. Cleanse and apply toner. Peel off and discard the film liner and apply mask to face, adjusting around the eyes and mouth. When you feel the sheet begin to bubble, leave on for 10 to 20 minutes. Remove mask and gently pat remaining serum into skin until fully absorbed. Do not rinse off.
