The skin's thick middle manager, quietly doing the work epidermis gets credit for.
means The dermis is the layer of skin beneath the epidermis, packed with collagen, blood vessels, nerves, and hair follicles that give skin its strength and feeling.
from From Greek 'derma' meaning skin or hide — the same root that gives us 'dermatology' and 'taxidermy.' 'Dermis' itself was carved out as a scientific term, essentially 'derma' trimmed down to its bare stem, to name the true skin layer once anatomists realized the outer epidermis ('epi-' meaning upon) was just a surface riding on top of it.
