What does subdermal mean?
Subdermal is an adjective meaning beneath the skin. It is most common in medicine, anatomy, dermatology, and cosmetic procedures, where it describes layers of tissue, fat, implants, injections, or other substances located below the skin’s surface. For example, subdermal fat lies beneath the skin, while a subdermal implant is inserted below it. The term is precise and specialized rather than conversational, so ordinary speakers may more often use general wording such as “beneath the skin” or “under the skin.” In medical usage, it is sometimes contrasted with superficial structures or with dermal conditions involving the skin itself. Although related to the term subcutaneous, subdermal is especially associated with tissue layers and the space immediately below the skin.

Where does subdermal come from?
Subdermal was formed in English by combining the prefix sub-, meaning “under” or “beneath,” with dermal, meaning “relating to skin.” The root ultimately comes through Latin cutis, “skin,” and related forms in derm-, as in dermis. The prefix-and-root construction follows the common English pattern of specifying the location of something with a prefixed form.
