Detailed explanation-1: -Cells divide in the basal layer, and move up through the layers above, changing their appearance as they move from one layer to the next. It takes around 2-4 weeks for this to happen. This continuous replacement of cells in the epidermal layer of skin is important.
Detailed explanation-2: -New cells travel up from the basale layer where they are made and push out the old, lackluster cells on the surface. This process usually takes about four weeks.
Detailed explanation-3: -The basal cells or “stem cells” of the epidermis are undifferentiated, proliferating cells that migrate upwards through all the five layers in a process known as keratinization. It takes about 30 days for the cells to migrate from the basal layer to cross the stratum corneum where they are finally shed.
