What treatment is used to remove dead skin cells on the surface?

Exfoliation is the process specifically designed to remove dead skin cells from the surface of the skin. This treatment helps in revealing the fresher, healthier skin underneath and is crucial for maintaining a smooth and radiant complexion. Exfoliation can be achieved through physical means, such as scrubs, or through chemical methods, like alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs).

While microdermabrasion also serves to remove dead skin cells, it is a specific technique involving a machine that sprays fine particles onto the skin to slough off the outer layer. Hydration and moisturizing, on the other hand, are focused on adding moisture to the skin rather than removing dead cells. Thus, exfoliation encompasses a broader array of techniques and products aimed at improving skin texture, making it the most suitable answer for the treatment of dead skin cell removal.
