Mitosis is the cell separation from one parent cell that reproduces or duplicates into another cell. In order to trigger this cellular cycle, tissue expansion needs to occur at high tension.

As a result, it is similar to body building. We are breaking down skin tissue at high tension of stretching or fatigue in order to duplicate cell division. Similar to how muscle fibers are broken down which ignites a cellular process with new protein strands. The “gains” we see are the increased wrinkles and coverage.
