Here's a breakdown:

* Keratinocytes: These are the primary cells of the epidermis, making up about 90% of its total cells. They are responsible for producing keratin, a tough, fibrous protein that gives skin its strength and resilience. Keratinocytes go through a process called keratinization, where they mature and die, forming a protective layer on the skin's surface.

* Other epidermal cells: While keratinocytes are the majority, there are other important cells in the epidermis, including:

* Melanocytes: These produce melanin, the pigment that gives skin its color and protects it from UV radiation.

* Langerhans cells: These are immune cells that help fight infection.

* Merkel cells: These are touch receptors that help us sense pressure.
