Blisters are an inflammatory phenomenon that form on the outer layers of the skin. They consist of liquid-filled bubbles that usually come out on the feet or hands, although they could sprout anywhere on the body, such as the mouth.

Causes of blisters

Blisters usually appear due to continuous rubbing or friction on the skin. However, they can arise from other causes such as burns, allergies, viral or bacterial infections, sunstroke, etc.

Why do blisters appear on the feet?

Most often, blisters appear on the feet due to friction between the skin and the shoe. It is more common in cases where the feet are misaligned and/or the wrong socks and shoes are used. In addition, the heat also promotes blisters, making the feet sweat more and slip, rubbing against the inside of the shoe. To prevent blisters, socks made of non-moisture-retaining fabrics, correctly sized and seamless, are recommended. As for the shoes, they should not be too tight or loose. If you’re wearing shoes that could cause blisters, put antiperspirant deodorant on high-chafing areas. Deodorant prevents moisture and therefore friction.

The body creates the blisters in order to protect an area of ​​skin that receives damaging friction. Thus, it creates a safe environment for the new skin to grow. The body will gradually reabsorb the fluid from the blister as new skin forms. In any case, blisters can be annoying and even painful. In addition, their healing without any intervention can be slow and, in some cases, they can burst on their own and become infected. Therefore, it is very important that you know how to cure blisters correctly, keep reading to find out!

Tips to heal blisters

Never pop a blister by squeezing it with your fingers. Avoid placing bandages or gauze pads on a burst, undrained blister, as they may remain attached to the skin. It is recommended not to remove the upper skin of the blister as it protects the “new skin” while it finishes healing. Try not to use other creams or medications that are not specifically for blisters, as they can have the opposite effect and infect the wound. Avoid wearing the same shoes that caused the blister or doing the activity that caused the blister until it heals completely.
