Cleanse your face and towel dry gently. Make sure that your face is dry. Now you take the mask from the packaging and gently unfold.
The mask is protected by 2(!) paper layers. Remove the first outer paper layer from one side of the mask, now apply the mask on your face. Remove the second outside protective paper layer, straighten and fit the mask around the nose and eyes to not leave any wrinkles in the bio-cellulose material.
Leave the mask on for 20 minutes to let the skin absorb the serum. After you removed the mask, there may be some serum left that you can pat into the skin with your fingertips until the serum is fully absorbed. Do not rinse your face.
