The most common cell in the skin is the keratinocyte. These cells make up approximately 90% of the epidermal cells and are crucial for producing keratin, a protective protein that forms the majority of the epidermis.
Keratinocytes undergo a process called keratinization, where they mature and produce keratin, forming a tough, protective layer on the skin's surface. This process is vital for shielding the body from environmental factors like UV radiation, bacteria, and physical damage.
