Use it on cleansed and dried skin, and remove the sheet mask from the pouch, and unfold it gently.
(Both sides provide the same effect for skincare.)
Hold the mask up by the temple part on both side, then place it over your face, starting from the eye holes.
Remove the mask after 15-20 minutes.
Massage the remaining serum until your skin completely absorbs it. (For oily skin, rinse off with water.)
