What does manual exfoliation involve?

Manual exfoliation involves the physical removal of dead skin cells from the surface of the skin. This technique typically uses hands, brushes, or other tools to achieve a smoother skin texture and promote healthy skin turnover. It may include the use of scrubs or other physical agents that help lift off the accumulated skin debris. This method contrasts with chemical exfoliation, which employs substances to dissolve dead skin, rather than physically scrubbing them away.

The other options do not accurately describe manual exfoliation. For instance, automated or machine-assisted procedures, typically referred to in other contexts or options, suggest a more technologically-driven approach that isn't characteristic of manual techniques. Professional training is not a requirement for manual exfoliation, as many basic techniques can be performed safely at home or during routine aesthetic treatments.
