What Causes Blisters?

Blisters happen when your skin gets rubbed too much and fills up with liquid inside it like a tiny water balloon.

Imagine you're wearing socks that are just a little bit too tight, or maybe your shoes have rough spots. Every time you walk, your foot rubs against those rough spots, it’s like having a friendly (but persistent) tickle on your skin. After a while, the rubbing hurts and makes your skin red and warm, just like when you sit in the sun for too long.

Now think of your skin as a water balloon. When it gets rubbed enough, it starts to split open, letting some liquid from inside come out, that's how blisters form!

Sometimes, if the rubbing doesn’t stop, the blister might pop on its own or you might even pop it with your finger like a real water balloon.

Blisters are your skin’s way of saying, “Hey, I need some time to heal!” So give them space and let them rest, just like when you take a break from playing after running around all day!
