Can Sheet Masks Really Help Our Skin? Dermatologists Weigh In

Need to illuminate tired or dull skin? Try popping on a mask with brighteners like vitamin C and niacinamide, such as Rael Vita Bright Sheet Mask ($13 for five) or Marmur Metamorphosis Repose Face Mask ($22), which was developed by a dermatologist and is further activated via a red LED light garnered via a downloadable app.
