To use this mask, first clean your face thoroughly. Then unfold the mask and apply it evenly on your face, adjusting it to fit your facial contours. Leave it on for 15 - 20 minutes, then remove the mask and gently pat the remaining essence into your skin. After use, you can continue with your normal skincare routine. Note that if you have sensitive skin, it's advisable to do a patch test first. Store the mask in a cool and dry place away from direct sunlight to maintain its quality.
