Keratinocytes
Keratinocytes are the main type of cells found in the outermost layer of the skin, known as the epidermis. They produce a protein called keratin, which helps form a protective barrier that keeps moisture in and harmful substances out. As keratinocytes move from the deeper layers of the skin to the surface, they undergo a process of maturation, eventually dying and forming a tough, protective layer that helps shield the body from environmental damage. This renewal process plays a vital role in skin health and overall protection against infection and irritation.

Keratinocytes are the primary cells found in the outer layer of the skin, known as the epidermis. They play a crucial role in protecting the body by forming a barrier against environmental damage, such as bacteria and UV radiation. These cells produce keratin, a tough protein that gives skin its strength and resilience. As they move up through the layers of the skin, keratinocytes gradually die off and form a protective layer on the surface, which is continuously shed and renewed. This process is essential for maintaining healthy skin and overall skin integrity.
