Numbuzin No. 4 Cooling Sheet Mask, 4 sheets

A cooling sheet mask that soothes troubled skin with a refreshingly cool sensation, just like taking it straight out of the refrigerator.

1. After washing your face, apply toner to your skin. 2. Remove the mask, unfold it, and place it over your entire face, aligning your eyes and mouth. 3. Leave it on for approximately 10 to 20 minutes, then remove the mask. 4. Use your palms to massage any remaining serum into your skin.
