Peelings

The skin is constantly generating new skin cells at the lower layer (the dermis) and sending them to the surface (the epidermis).  As the cells rise to the surface they gradually die and become filled with keratin. These keratinized skin cells are essential because they give our skin its protective quality. But they are constantly sloughing off to make way for younger cells.

As we age the process of cell turnover slows down. Cells start to pile up unevenly on the skin's surface, giving it a dry, rough, dull appearance. Exfoliation is beneficial because it removes those cells that are clinging on, revealing the fresher, younger skin cells below.
