Which of the following describes sloughing off of the epidermis?

Desquamation is the process by which the outer layer of the skin, specifically the epidermis, sheds dead skin cells. This is a natural and continuous process that helps maintain healthy skin by allowing new skin cells to emerge from underneath. The shedding of these cells can be influenced by factors such as skin health, environmental conditions, and overall hygiene.

Other terms related to skin conditions, such as disinfection, discoloration, and edema, refer to different phenomena. Disinfection involves eliminating pathogens to ensure cleanliness; discoloration pertains to changes in skin color often due to various conditions; and edema refers to swelling caused by the accumulation of fluid in the tissues. Each of these terms is distinct and does not describe the shedding process of the epidermis. Hence, desquamation accurately captures the process in question.
