The word epidermis originates from Greek epi- (upon) + derma (skin), literally meaning "upon the skin." It entered Late Latin as epidermis and was adopted into English in the early 17th century to describe the outer layer of skin in anatomical studies. The term reflects the layered structure of skin, with the epidermis being the visible, protective surface.
The epidermis constantly sheds dead cells to maintain healthy skin.
Sunburn damages the epidermis, causing redness and peeling.
Melanocytes in the epidermis produce pigment to protect against UV rays.
