Today, experiments and studies are now showing far more fibroblast activity resulting from mechanically stretched skin than the typical wound repair brought about from actual cuts, or cosmetically controlled procedures such as punchers, abrasions, laser, etc.  It is important to note fibroblasts cells do not respond to everyday physiological strain on the skin i.e., massage, facial exercise, vibration, etc.  To promote the highest level of fibroblast activity, the skin must be stretched beyond normal levels.  Remember, it’s all about wound repair, so your goal is to bring about microscopic levels of damage, again, microscopic levels not visible to the naked eye.

I am fully aware of the idea that deliberately stretching the skin beyond the norm could cause permanent damage.  This idea comes from the die-hard misconception that any stretching of the skin will permanently stretch it causing sag; which is total nonsense.  It is true that the skin can be stretched to increase the amount of skin needed for certain medical procedures (grafts) but the procedure for this type of stretching takes months and months of continuous stretching without any let-up in tension.  Stretching and releasing the skin within a matter of a few seconds such as in Cross Stretching cannot and positively will not cause permanently stretched skin.
