What is a blister?
A blister is an area of raised skin with liquid inside. They are your body’s clever way of protecting itself from pressure and friction.
A high degree of friction tends to cause the outer layer of skin, the epidermis, to separate from the layers beneath causing fluid to fill the space. This is an attempt to cushion the wound beneath from further pressure or friction and to lock out causes of infection. Unfortunately, blisters can be easily burst by more pressure. Both intact and deroofed blisters are extremely painful if not treated and can easily become infected. This is also the main reason why blisters should not be popped. Blisters on the feet, hands and fingers are some of the most frequent.
How to treat a blister
Tips for blister treatment:
- Self-surgery is not recommended, e.g. do not puncture the blister and don’t remove any outer layers of skin, which can cause infection.
- Make sure your skin is clean and dry before applying the blister plaster.
- Attach the plaster without wrinkles and press firmly.
- Don’t change the plaster until it falls off.
How to prevent blisters
As blisters on the heels and feet are very common, it’s important to wear properly fitting shoes. Break in new shoes slowly, removing them periodically before pain begins, rather than wearing them for an entire day. Make use of Elastoplast Pressure Stop Plasters to create an additional layer between sources of friction and skin.
Blisters are more likely to occur in moist conditions so aim to keep your feet as dry as possible e.g. with Elastoplast Silver Active Spray.
