The epidermis is the outermost layer of the skin, serving as a protective barrier between the body and the external environment. It consists of several layers of cells and plays a crucial role in regulating temperature, preventing water loss, and shielding the body from harmful substances and pathogens. The epidermis also contains melanocytes, which produce melanin, the pigment responsible for skin color.
