These super hydrating sheet masks—you get four in a pack—are made with prebiotics, marine collagen, seaweed and edelweiss extracts, and hyaluronic acid to help smooth the appearance of fine lines and wrinkles, brighten, plump, and deeply nourish skin. Each mask is tucked between two mesh layers, so gently peel back the top layer and smooth the mask over your skin. Once it’s on, peel off the outer layer and leave the mask  on for twenty to thirty minutes; when you peel it off, gently massage any excess serum into skin for a powerful, rejuvenating skin treatment. For best results, use once a week.
