Esthetics Core Written Practice Test

The term that best describes the production and shedding of skin cells is known as cell turnover. This process involves the entire life cycle of skin cells, beginning with their formation in the deeper layers of the skin and continuing as they migrate to the surface, where they eventually die and are shed.

During cell turnover, new cells push old cells to the surface, promoting a healthy complexion and ensuring that the skin can effectively renew itself. This is a vital part of maintaining skin health, as it helps to remove dead skin cells, allowing for fresh, new cells to take their place, which can contribute to a more radiant and youthful appearance.

While exfoliation is related to the physical removal of dead skin cells from the surface, it does not encompass the entire cycle of cell production. Dermabrasion is a cosmetic procedure that mechanically sands the skin, and hyperkeratosis refers to thickening of the outer layer of skin, typically due to excessive production of keratin. These concepts are associated with skin care and conditions but do not specifically describe the complete process of skin cell production and shedding as accurately as cell turnover does.
