Exfoliation is defined as the sloughing off of what type of skin cells?

Living epidermal cells Nonliving dead skin cells Dermal tissue Inflamed cells

Correct Answer:

Nonliving dead skin cells

Explanation:

Exfoliation is the process of removing the outermost dead skin cells from the surface of the skin. Those cells are nonliving and dead keratinocytes that form the stratum corneum, the top layer of the epidermis. Living epidermal cells sit deeper in the skin and are not shed during exfoliation. Dermal tissue lies beneath the epidermis, and inflamed cells aren’t the typical targets of exfoliation. Exfoliation can be mechanical or chemical, both aiming to slough off these nonliving dead skin cells to reveal smoother skin and improve absorption.
