Where does skin come from?

Skin originates from the ectoderm, one of the three primary germ layers formed during embryonic development. As the embryo develops, the ectoderm differentiates into various structures, including the epidermis, the outermost layer of skin. The dermis, which lies beneath the epidermis, is derived from the mesoderm. Skin plays a crucial role in protection, sensation, and regulation of body temperature.
