Here's a sheet mask you'll want to stock up on in winter. The top-rated Dr. Jart+ Dermask Water Jet Vital Hydra Solution ($6) boasts moisturising hyaluronic acid and algae extract that supports your body's natural collagen creation and leaves skin looking completely refreshed. The serum in the mask works to strengthen the skin's barrier and help to prevent water loss. Plus, Sephora shoppers noted it's good for even sensitive skin and reducing redness, too.
