epidermis
Skin's outermost stratum
The epidermis is the outermost layer of skin—the thin protective covering that forms the body's first barrier against the environment.
In botany, epidermis refers to the similarly protective outer layer of leaves and stems.
The word sometimes appears in casual speech as a fancy or humorous substitute for skin: Watch the epidermis, buddy.
