What are keratinocytes?

Keratinocytes are the main cells that make up your skin.

Imagine your skin is like a superhero suit, and keratinocytes are the tiny builders who put it together. They're like bricklayers, stacking themselves on top of each other to form a strong wall that protects you from germs, dirt, and even the sun.

Keratinocytes live deep inside your skin, in a place called the epidermis, think of it as the outer layer, like the paint on a house. These cells slowly move up toward the surface, getting tougher along the way. It’s like when you put on layers of clothes to stay warm: the deeper layers are softer and more flexible, but as they rise, they become harder and stronger.

When they reach the top, they’re like the outer layer of a shield, ready to take on whatever comes your way! Once they're done their job, they fall off, and new ones take their place. It’s like a never-ending game of tag, where each player gets a turn being in the front line.
