What Would happen if the dermis was absent from the body?

If the dermis were absent, the skin would lack its structural integrity and support, leading to severe vulnerability. The epidermis, which is the outer layer of skin, would be unable to properly adhere and could easily tear or become damaged, resulting in increased susceptibility to infections and dehydration. Additionally, the absence of the dermis would disrupt the functions of blood vessels, nerves, and hair follicles, impairing sensation and thermoregulation. Overall, the body would face significant challenges in protection and homeostasis.
