The epidermis is a thin layer that provides a protective cover of skin cells that your body continually sheds.The epidermis contains three main types of cells: 1  Squamous cells lie just below the outer surface and function as the skin's inner lining. Basal cells, which produce new skin cells, sit beneath the squamous cells. 2  Melanocytes â which produce melanin, the pigment that gives skin its normal color â are located in the lower part of your epidermis. 3  Melanocytes produce more melanin when you're in the sun to help protect the deeper layers of your skin.
