<P> The epidermis is the outermost of the three layers that make up the skin , the inner layers being the dermis and hypodermis . The epidermis layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through transepidermal water loss . The epidermis is composed of multiple layers of flattened cells that overlie a base layer ( stratum basale ) composed of columnar cells arranged perpendicularly . </P>
