With a normal cream mask, you have to apply the paste over your face and then wait for ten or twenty minutes to let it dry. They can cleanse the skin of impurities and are good to remove blemishes and toxins. But you are not supposed to use a cream face mask on a daily basis. You have to give enough time for the natural oils on the skin to replenish. But sheet face masks are a lite version of paste masks. They are serum-soaked sheets of fabric, paper or gel. Because they come cut in the shape of a face, with cutouts for eyes, nose and mouth, you can just put them on your face without any fuss.
