New Skin Liquid Bandage Spray can be used to protect cuts and scrapes and can help stop blisters and calluses from forming, and covers painful hangnails. After cleaning the affected area, dry thoroughly and apply New Skin Liquid Bandage Spray. Once dry, your cuts, blisters, or other small wounds are protected from dirt and germs. The treated area is now water-proof, flexible, and allows your skin to breathe for 24-48 hours before you need to reapply. You should not use New Skin Liquid Bandage Spray on any skin area that appears to be infected as this should be tended to by a doctor first.
