Rina and the other students are learning about the science of exfoliation for example the rate of cell mitosis and migration from the dermis to the top of the epidermis is called the cell renewal factor.
- Our Cell Renewal Factor (CRF), also known as cell turnover rate, goes down as we age.
- The process of cell turnover is how our skin creates fresh skin cells that move up the epidermis from the base to the top before being shed. This prevents a buildup of dead cells on the skin's surface.
- The cell ascends through the epidermis until it reaches the stratum corneum, the top layer of skin.
- A "dead" skin cell is one that is tough, dry, and flaky once it reaches this layer.
- The skin should ideally continue to produce new skin cells, which push older cells out from beneath. Throughout the body, this desquamation process takes place.
