People use the term microneedling to include many things, Jody considers microneedling to be a technique using a smaller needle, like a Dr. Pen or other a dermaroller, and is intended to cause damage to the skin which triggers your body’s natural healing response as a way to revise areas of concern - no healing serum is added while needling. Tattooing is the placement of pigment or ink in an area of concern to blend it with the appearance of the surrounding skin. ISR is closest to tattooing as you are using a rotary tattoo machine - more powerful than a microneedling machine - however instead of ink you are placing healing serum in the treatment area.
