Sheet masks have been popular in Asia for a long time, and now these smart masks have taken Europe by storm! They are both effective and super easy to use with the right dosage in a smart disposable package. Each sheet mask is full of nutritious serum. Place the mask on clean skin and relax for a little while. Sheet masks are not supposed to be washed off, but followed up by your usual day/night cream. At Lyko you will find a variety of different sheet masks for every skin type and need.
