What type of exfoliation removes dead skin cells from the surface?

Physical exfoliation is the method that involves the manual removal of dead skin cells from the surface of the skin. This is typically achieved through the use of gritty ingredients or tools, such as scrubs with granular components or exfoliating brushes. The process sloughs away the uppermost layer of skin, promoting a smoother texture and a brighter complexion.

In contrast, chemical exfoliation uses acids or enzymes to dissolve dead skin cells, rather than physically scrubbing them away. Natural exfoliation might involve using substances found in nature, but it doesn't specifically pertain to the mechanism of removing dead cells through physical means. Hydration exfoliation is not a recognized method within the standard categories of exfoliation techniques. Thus, the focus on the manual action of scrubbing leads to the understanding that physical exfoliation is the correct answer for removing dead skin cells from the surface of the skin.
