The "horny layer" is an older, less formal term for the stratum corneum. This is the outermost layer of your skin, composed of dead cells filled with keratin. Think of it as a protective shield π‘οΈ against the outside world. It prevents dehydration, blocks harmful substances, and resists abrasions. While technically correct, "stratum corneum" is preferred in scientific contexts. Itβs similar to calling your grandma "old lady" β accurate but maybe not the nicest way to say it.
