Which technique would you use to remove dead skin cells from the surface of the skin?

Exfoliation is the technique specifically designed to remove dead skin cells from the surface of the skin. This process can involve the use of physical methods, such as scrubs or brushes, or chemical methods, such as alpha hydroxy acids and enzymes, to help slough away the outermost layer of dead skin. Regular exfoliation reveals fresher, healthier skin underneath and can improve the overall texture and appearance of the skin.

Moisturization focuses on hydrating the skin and maintaining its barrier function but does not remove dead skin cells. Hydration refers to the process of increasing water content in the skin, which is essential for skin health, but again, it doesn't directly involve the removal of dead skin. Rejuvenation typically encompasses a broader range of treatments aimed at improving the skin's overall appearance and may include exfoliation as one component, but it is not a specific technique for dead skin removal. Therefore, exfoliation is the most precise answer for the task of eliminating dead skin cells.
