Being able to spend an entire day shopping and then dance the whole night through is great – but all it takes is a painful blister to spoil the fun. We tell you how to treat them using the Elastoplast Blister Plaster and prevent them from reappearing.

What is a blister?

A blister is an area of raised skin with a small pocket of watery liquid inside. Blisters form on the hands and feet from continuous rubbing and pressure. You can develop blisters on your feet from wearing uncomfortable or ill-fitting shoes for just a few hours.

How does a blister form?

Repetitive rubbing and pressure will eventually lead to the separation of the epidermis (the outer skin layer) from its lower skin layers, and this leads to the formation of a blister containing tissue fluid. This liquid is supposed to cushion the wound and protect it from further pressure. The blister, then, is actually a clever self-protective measure of your body.

The blister’s outer membrane is what successfully protects the wound - from further pressure, and from dirt and bacteria infecting the body.

Unfortunately, a blister is painful and can burst if exposed to more pressure and friction. This leaves an open wound that is extremely painful and can easily become infected. An infected blister is filled with yellow or green pus, and feels hot. Surrounding skin appears red, though this can be difficult to notice on darker skin tones. Infected blisters need treatment, otherwise they could lead to a blood or skin infection. Your GP may prescribe antibiotics to treat an infected blister.

Should you pop blisters?

The best way to deal with a blister is to leave it intact.

As long as it is covered, the wound is protected from infection. A blister should not be opened because the blister roof protects against additional infection. If the blister comes open accidentally, don‘t pull off the outer skin layer. Leave it alone to heal, and cover it with a blister plaster. Applying a blister plaster will do three things:

  1. Help to avoid additional pressure from shoes on to the blister
  2. Protect the delicate layer of skin on top of the blister (the blister roof) until the blister is ready to drain by itself
  3. Protect an open blister from infection and external influences such as water, dirt and bacteria

A blister requires patience, and there are a few measures you can take to prevent pain and ensure fast wound healing.

Blister Plasters

As soon as you can feel a blister developing, apply a plaster. Elastoplast Blister Plasters are one of the first self-help options for blister treatment. These cushion the affected area and protect even an open blister from infection and dirt. The plaster will also help relieve the pressure-induced pain and accelerate the healing process.

Don’t change the plaster unless it comes off by itself, giving the blister time to heal. With hydrocolloid technology, the Elastoplast Blister Plasters create the optimal moist environment for wound healing that allows the wound to heal faster. To avoid disturbing the healing process, leave the plaster in place for several days – only change it if it starts to come off by itself.

Optimal healing for blisters

"Wounds heal best in a humid environment". This a clinically-proven learning that the plaster is based upon. In a protected environment the blister will heal best and all by itself. Breaking the protective layer of skin of a blister allows bacteria to enter the wound, which is medically considered an open wound. Nevertheless, if this does happen, you should disinfect the punctured blister (for example with an antiseptic spray) and cover it with a blister plaster. It will protect the affected area from further pressure, friction and other harmful external influences.

to heal"

Thanks to our hydrocolloid technology, the Elastoplast Blister Plasters create the optimum environment for the wound to heal. The hydrocolloid material of the plaster will take up superfluous liquid from the wound and create a protective gel cushion over it at the same time, which will keep its environment humid and thus let the wound heal quickly.

How to pop a blister

As explained, popping a blister disturbs the natural healing process and is best avoided. Underneath the blister, new skin is formed and the fluid is absorbed as part of the healing process.

While they usually heal within a few days, sometimes it's not always practical to leave blisters alone - especially if they're painful, large or in an area where they're likely to be ruptured. So in some instances, popping a blister may actually be the best way to protect it against infection.

If you’re unsure how to pop a blister, follow these steps to do it safely and reduce the risk of infection:

  1. Wash your hands and gently clean the surface of the blister with an antiseptic wash or the Elastoplast Wound Spray.
  2. Sterilise a thin needle with boiling hot water or rubbing alcohol for at least 20 seconds.
  3. Carefully puncture the blister with one or two small holes around the edge, allowing the fluid to drain on its own. White or yellow pus can indicate an infected blister, which may require medical attention.
  4. Leave the skin over a broken blister intact - this acts as a protective cover for the new skin underneath
  5. Apply the Elastoplast Wound Healing Ointment to the blister.
  6. Tightly cover the blister with a small dressing, or a skin-friendly plaster such as the Elastoplast Blister Plaster or Sensitive plaster.

How to prevent blisters

If you're prone to suffering from blisters, read our tips on blister prevention:

  • Wear comfortable shoes that fit correctly, especially if you know that you’ll be walking a lot or on your feet for a long time. The right choice of shoes can help prevent future pain, and shoes are usually the reason behind the formation of blisters. Remember to gradually break in new shoes before you wear them on a big shopping tour or sightseeing trip.
  • Wear better socks, such as non-cotton ones that wick away moisture. Consider doubling up on socks prior to any blister-inducing activities. This allows one layer to soak up moisture while the other provides extra padding.
  • Apply a foot cream regularly for basic foot care. This will make the skin on your feet more supple and hydrated and therefore more resistant to developing blisters.
  • Humidity and leather are not a good mix: keep your feet as dry as possible. Wet shoes, boots and socks will cause blisters far quicker than dry ones.
  • Working out or running? Wear special socks that are enforced on toes or heels and don‘t have seams.
  • Cover up areas that are prone to blisters for an extra layer of protection.
  • When going on city trips or for longer walks, be prepared by taking an Elastoplast Blister Plaster with you in your bag. This is conveniently equipped with a case to ensure that your five large plasters do not get lost on your adventures.
  • Add talcum powder to your shoes and socks to help absorb moisture.
  • Consider keeping calluses instead of removing them, as they help to remove your feet.
