When blisters appear, they can be sore, itchy and uncomfortable. So, should you pop blisters? The temptation to burst these fluid-filled bubbles can be a strong one.

Why you shouldn’t pop a blister

Popping a blister may seem like a simple solution but doing so means the skin will be more susceptible to germs. It’ll also likely be more painful as further friction is inevitable, and could lead to scarring[2]. In fact, bursting a blister will actually slow down the healing process. Left alone a blister will naturally heal on its own within three to seven days.

As blisters are sore and can affect day-to-day activities, one of the best and easiest ways of helping a friction blister and alleviating pain is by using a blister cushion[1].

The cushions will also help prevent further rubbing and remove excess moisture, enabling the blister to heal faster. Compeed blister cushions –provide instant pain relief – and come in a range of sizes that will allow you to go about daily activities, including sports, without worrying about damaging the blister even more. They provide an optimal healing environment with added cushioning, when compared to regular bandages[3].

What if a blister pops?

You can’t always prevent a blister from popping. If this happens, act as soon as you can to minimize the risk of infection.

If you’ve noticed the blister has burst, resist picking at the skin and instead, allow the liquid to drain. You should then follow these steps:

  1. Wash the area delicately with warm water.
  2. Dry off the area. With a regular bandage, you may wish to apply some antiseptic cream. With Compeed blister cushions, apply over the dry area.
  3. Cover the sore with a bandage. For better results, use a Compeed blister cushion to cover the bandage and support the healing process.

If a blister has burst, it’s important to watch out for signs of infection. These can include:

  • Redness, pain and swelling around the area
  • A high temperature
  • Pus oozing from the blister

If you experience any of the above or are concerned about infection, seek treatment from a medical professional as soon as possible.


Sometimes blisters are inevitable. The first line of defense against them is prevention using cushions to cover and protect. If one does occur, remember that it will likely go away naturally within a week. It’s best not to try to pop the blister and instead cover with a cushion pad to protect it from infection and help the blister heal. But if you simply can’t resist, cleanliness is key to avoiding infection.
