Esthetics Core Written Practice Test

The process that describes the shedding of keratinocytes from the skin is known as desquamation. This is a natural and continuous process where the outermost layer of the epidermis, which consists of dead skin cells or keratinocytes, is sloughed off to make way for newer cells that have pushed up from the lower layers of the skin.

Desquamation plays a crucial role in maintaining skin health and appearance by allowing for cellular turnover, helping to remove damaged or old cells and enabling the skin to rejuvenate. This process also supports proper skin function, as it helps prevent the buildup of dead cells that can lead to clogged pores and other skin issues.

In contrast, regeneration refers to the process of repairing and renewing tissues, ossification is related to the formation of bone, and exfoliation typically describes the physical or chemical removal of dead skin cells rather than the biological process of shedding itself.
