The infection can also cause single or multiple blisters. Another factor that causes blisters is inflammation.

Blistering due to contact with hot objects or hot liquids

One of the main causes of blisters is when the skin is damaged by contact with hot objects or hot liquids such as hot oil, acid and boiling water. First-degree inflammation does not cause blisters, only the skin becomes red and there is swelling, pain, and mild burning. But in secondary inflammation, the entire outer layer of the skin is destroyed and blisters of different sizes are formed on the surface of the skin. This type of wound may require care and treatment for up to three weeks. In third-degree inflammation, the entire subcutaneous layer of the skin, muscles, blood vessels, nerves, and even bones are destroyed, and the skin becomes charcoal white and red, tending to black and without pimples.

Necessary measures to prevent blisters

Before taking any action on the burn, try to cool the burned area to prevent blistering and further damage to the skin and other areas under the skin. It is better to use drinking water. Immediately run the burn under cold water for 10 to 30 minutes or place it in a bowl of water.

Using a salt water solution with a concentration of half a teaspoon of salt in a glass of chilled boiled water is also useful for controlling skin blisters. Washing the blisters every 2 hours with this solution can effectively reduce the size of the blisters and reduce the pain and irritation.

The importance of blister treatment

The importance of blister treatment is that a large amount of body water is removed from the blood circulation and accumulates in the blister, which can cause shock and anesthesia if the number of blisters is large or large. Another point is that the fluid of blisters and damaged skin is a suitable place for various microbes to enter and grow. Therefore, if the blisters are not treated properly, the person will suffer from infection and the resulting complications.

Most blisters do not require treatment and will go away on their own, as the top layer of skin often prevents infection. You can bandage it, which will cause the liquid in the blister to be absorbed by the tissue and the blisters will disappear. Never puncture a blister unless it becomes very painful, as the skin over it prevents infection and if you remove the skin, it is prone to infection. Even blisters caused by infection are temporary but need treatment. It is also important to note that some blisters, such as pemphigus, have no cure, but can be controlled with medication.
