The outer layer of the skin, known as the epidermis, primarily consists of keratinocytes, which produce keratin, a protein that helps protect the skin. This layer also contains melanocytes, which produce melanin responsible for skin color, and Langerhans cells, which play a role in immune response. The epidermis is avascular, meaning it does not contain blood vessels, and it is constantly renewing itself as older cells are shed and replaced by new ones from the deeper layers.
