Most blisters are caused by friction or minor burns and new skin will form under the blister and then the fluid is absorbed

  • DO NOT POP THE BLISTER unless it is large, painful and likely to be further irritated
  • The fluid-filled blister keeps the underlying skin clean which prevents infections and promotes healing
  • If you have to pop a blister, use a sterilized needle or razor blade, put it in a flame or rinse it with alcohol
  • Wash the area thoroughly, then make a small hole and gently squeeze out the fluid
  • If the fluid is white or yellow, the blister may be infected and needs medical attention
  • DO NOT remove the skin over the broken blister, the new skin needs it as a protective cover
  • Look for signs of infection developing, including pus drainage, red or warm skin surrounding the blister, or red streaks leading away from the blister

How can I prevent blisters?

  • Wear gloves
  • Break in new shoes gradually and put petroleum jelly on an adhesive bandage on the area that takes the rub, before the blister happens
