Ideally, you should not pop a blister. When the wound is left intact, the fluid sealed inside the blister will soothe the bottom layer of the damaged skin and keep it moist while the area heals naturally. In addition, a closed wound is less likely to get infected.
To help promote proper healing of a blister:
- Wash the blister and the surrounding skin with water and a disinfecting soap. If the blister is popped, do not remove the broken skin.
- Cut a hole just a little larger than the blister in a piece of protective padding, such as moleskin or felt, to help cushion the injured area from additional friction or pressure.
- Gently place the protective padding over the blister, making sure that any adhesive affixes to the healthy skin around the wound and not directly on the blistered skin.
- If the blister is open, you should also apply antibiotic ointment over the damaged skin and cover it with a piece of sterile gauze.
At least once a day, remove the dressing carefully and inspect the wound. If the blister shows no signs of infection, repeat the above steps with a new dressing.
If the wound becomes additionally painful or reddened, secretes colored pus, develops yellow crusting or does not show signs of healing after a few days, consult a medical professional for additional advice.
