Wait, can I pick the WRONG sheet mask?
Not really. Sheet masks are paper, cloth, or a gel-like material saturated with serum that contains moisturizers and extracts, explains Birnur Aral, Ph.D., Director of the Beauty Lab at the Good Housekeeping Institute. Most claim to hydrate, firm, lift, plump, brighten and lighten skin, but our Lab determined that the ingredients in the serums are all quite similar. So you really can't make a bad choice!
