Humans have three primary layers of skin: the epidermis, dermis, and hypodermis (subcutaneous layer). The epidermis is the outermost layer, followed by the dermis, which contains connective tissue and blood vessels, and the hypodermis, which consists of fat and connective tissue that anchors the skin to underlying structures. Throughout life, humans continuously shed and regenerate the epidermis, but the overall number of skin layers remains constant.
