What does epidermic mean?
"Epidermic" is a formal adjective meaning of or relating to the epidermis — the tough, protective outermost layer of the skin. Like its far more common synonym "epidermal," it belongs to the vocabulary of medicine, biology, and dermatology, where precision about which skin layer is involved matters: an epidermic change affects the surface tissue rather than the underlying dermis. The word appears chiefly in clinical descriptions, laboratory reports, and scientific literature, as in "epidermic cells" or "the epidermic layer." Because it so closely resembles both "epidermal" and "epidemic" in spelling and sound, writers should take care to choose the intended term. For most purposes "epidermal" is the natural choice, but "epidermic" remains a legitimate, if less frequent, variant with the same technical force.

Etymology of epidermic
"Epidermic" derives from "epidermis," formed from the Greek elements epi- ("upon") and derma ("skin"). The noun "epidermis" entered scientific Latin before passing into English in the early 17th century, and adjectival forms such as "epidermic" and "epidermal" were later coined to describe things pertaining to it. The root derma also gives English words such as "hypodermic" and "dermatology."
How epidermic is actually used
A formal, technical term found almost exclusively in medical, anatomical, and scientific writing. In everyday and even most clinical usage, "epidermal" is strongly preferred, making "epidermic" comparatively rare.
Easily confused with epidermic
"Epidemic" refers to the rapid spread of disease through a population, while "epidermic" relates only to the outer layer of the skin.
"Epidermal" is the far more common adjective for the same meaning; "epidermic" is a rarer variant of it.
