Blisters

Skin Conditions

Blisters are clear, fluid or blood-filled sacks on the skin. The majority result from prolonged pressure on, or rubbing of, the skin causing a shearing force between skin layers. Blisters can arise from illness, certain infections, allergic reactions or burns.

Prevention

  • Wear protective gloves when performing repeated chores with your hands, such as hammering
  • Wear properly fitted shoes that do not rub your feet
  • Avoid excessive time in the sun and wear a sunscreen with SPF 15 or greater

Treatment

Home care  Home Care

  • Protect the blister from further rubbing
  • Leave the blister alone if it has not broken. Most heal best when left without special treatment
  • Wash the blister 2-3 times a day with soap and water if it has broken. Do not remove the flap of skin covering the top of the blister unless it is very dirty. Apply a nonprescription antibiotic ointment, such as bacitracin, followed by a bandage. Do not use alcohol or iodine.
