Dead cells on the epidermis, known as corneocytes, play a crucial role in providing a protective barrier for the body. These cells are constantly shed and replaced by new cells underneath, helping to maintain the integrity of the skin. Additionally, the dead cells help to prevent water loss and protect the body from external pathogens and UV radiation.
