What are blisters?

A blister is like a tiny bubble that forms on your skin when it gets hurt or rubbed too much.

Imagine you're wearing socks that are super tight, they press and rub against your foot all day long. Your foot feels uncomfortable, and after a while, your skin starts to feel sore and hot. That’s because the layer of skin is getting pushed up by the pressure, like a piece of paper being lifted by something underneath it.

Blisters are exactly that, little pockets of fluid that form on top of the skin when it gets rubbed or burned. They act like a protective shield, helping your skin heal from the inside out.

Think about when you wear shoes that don’t fit well, or maybe you carry a heavy backpack all day long, your skin can feel like it's being squeezed and moved around. This is similar to how a sock might rub your foot too much. Over time, this repeated pressure causes the top layer of your skin to lift up, creating a blister.

Sometimes, blisters even have fluid inside, just like a tiny water balloon, that’s your body helping you heal!
