Fact Checked
Overview Of A Blister
- A blister is a lump filled with fluid that develops when the skin’s outer layer is damaged.
- The fluid takes place beneath the injured skin and protects the new skin growing beneath it. When the new skin grows, the body gradually reabsorbs the liquid.
- The process normally takes 3–7 days. Sometimes the blister splits on its own.
- GP’s sometimes use the expressions ‘vesicle’ for a minor blister and ‘bulla’ for a larger blister.
The Causes Of Blisters
- Constant rubbing and friction;
- Burns;
- Stings or bites from insects; and
- Viral infections such as cold sores.
First Aid Steps
- Do not break the blister. Let it heal on its own to avoid infection.
- Make certain the blister and adjoining skin is sterile.
- Cover the blister with a soft dressing if it’s in an area that might get bumped or scoured throughout the day.
- If the blister splits, let the fluid drain on its own. Then, clean it with soap and water and place some antibacterial cream on it.
- Chat with your GP if there is an increase in irritation around the blister, swelling, or discharge since these are the symptoms of an infection.
- You must also chat to your general practitioner if have extensive blistering, or if you feel sick as a result of the blisters.
What Can Your Doctor Do?
If the blister starts to become infected, it might require the following medical care:
- Draining the secretion or fluid under hygienic surroundings and the application of suitable treatment and dressings.

Your general practitioner might also be able to offer you medicines to treat any allergy that may be present.
