This is the Skinfood Pantothenic Water Parsley Mask. They said it uses a microfiber slim-fit sheet, and indeed, the sheet is very thin. Perhaps because it is so thin, it adheres well to the skin without lifting, which I really like. I use it whenever my skin feels dry, and I love how I can really feel it replenishing moisture. Since it is a Skinfood product, I use it with confidence that it is made safely with naturally derived ingredients.
