Just below the epidermis lies the second layer, the dermis. The dermis, although it contains blood vessels, nerves, and hair follicles, is primarily made up of a protein called collagen.. This protein forms a network of fibers that provides a framework for the growth of cells and blood vessels.ust below the epidermis lies the second layer, the dermis.
