All of the masks contain sodium hyaluronate and aloe vera gel. Some of them also contain soluble collagen. However, these are not free from parabens and triethanolamine.
The cloth masks are very lightly-scented, well-saturated with serum, and fit the contours of the face rather well. They are to be left on for 20 to 30 minutes and after removal, the remaining serum massaged in. I prefer to dab it off with a tissue, and though it's hydrating enough on its own, follow up with a moisturizer.
