That's Correct!
It's Wrong!
The outermost layer of the epidermis is called the stratum corneum. This layer is composed of dead skin cells that have become flattened and filled with keratin, a tough protein. The stratum corneum acts as a protective barrier for the underlying layers of the epidermis and helps to prevent water loss and protect against external irritants and pathogens.
