Treating a Minor Burn With Blisters

A blister forms when heat separates layers of skin and fluid collects between them. The skin roof helps shield the tender surface underneath, so puncturing it can expose the area to germs and delay healing. A small, superficial burn may be managed at home when the skin is otherwise intact and pain is settling.

Keep rings, watches, and tight items away from the injured area because swelling can develop. Do not apply ice, butter, oils, or adhesive products directly to the burn.

Run cool tap water over the burn for a sustained period as soon as possible, then gently remove nearby clothing or jewellery that is not stuck. Pat the surrounding skin dry, avoid rubbing the blister, and place a sterile non-stick dressing or clean loose covering over it. Change the covering if it becomes wet or dirty. A pharmacist or clinician can advise on suitable pain relief and dressings.

Arrange prompt medical assessment for a burn on the hand or a finger joint, a large or deep blister, white or charred skin, numbness, increasing swelling, spreading redness, pus, fever, or pain that is becoming stronger. Get emergency help for breathing difficulty, faintness, confusion, or a burn caused by electricity or a chemical. Further guidance is available through [Minor Burn Treatment](/treatments/acute-and-urgent-care/minor-burn-treatment/) and [Wound Care and Dressing](/treatments/acute-and-urgent-care/wound-care-and-dressing/).

Ask whether the blister should be dressed in a particular way, which pain relief is suitable for you, how to recognise infection, and whether your tetanus protection needs checking.
