What is a one-sentence summary of the following article?
This will protect the affected area from further injury or infection. You can also use sterile gauze and adhesive tape. Change your bandage at any time of the day that works for you, as long as your wound is freshened up once per day. When you change your bandage, wash your wound and reapply Neosporin to keep your wound moist and clean. Large bandages are better to cover the size of bigger wounds. You can find them in drug stores or most grocery stores. If you aren’t sure of what size bandage to use, ask your doctor. If you have Neosporin leftover beyond the expiration date, get rid of it. Expired Neosporin will not heal your wounds and may cause further infections.

Summary:
Cover your wound with a bandage after you apply Neosporin. Change your bandage 1 time a day to keep your wound clean and dry. Use larger bandages for serious wounds. Throw away expired Neosporin.
