What is the process like?

FSN needles are distally inserted to the affected area. The needles are then manipulated and act on soft connective tissue (subcutaneous layer),  where collagen fibers are most abundant.  During the manipulation of the needle, collagen fibers would then wind and tighten around the needle shaft. FSN abstains from the muscle and deep fascia layers.
