dead skin cells forming the outermost protective layer
Corneocytes are the dead, flattened cells that make up the outermost layer of the skin, known as the stratum corneum. They act as a protective barrier, preventing water loss and shielding the underlying living cells from environmental damage. For professionals, it's important to note that corneocytes are rich in keratin and are the end result of the keratinocyte differentiation process.
