Blisters happen when your skin rubs against something over and over, like walking in new shoes. This rubbing causes a layer of fluid to fill up between the top part of your skin and the rest of it, that’s why blisters feel full and poppable! It's like when you wear socks inside out all day and your feet start feeling funny.
Examples
- Holding a hot pan with bare hands and developing a blister after minutes
- Carrying heavy bags all day and getting blisters on your palms
