Yes, use the single needle in combination with a dermastamp. Basically, dermarolling and needling are novel procedures and nobody knows absolutely the best/ideal routine for individual skin conditions so a little improvisation from customers is welcome. Not to mention that not everybody reacts the same to dermarolling/needling so giving the best general instructions for everybody is really difficult.
Infadolan and copper peptides have different functions. Infadolan is mainly for the protection of the skin right after dermarolling, for keeping it moisturized and to create good conditions for skin regeneration.
You can apply copper peptides after dermarolling and when it has been absorbed, apply a very small amount of Infadolan on top of it. If you choose not to use Infadolan, that is also OK.
Concerning releasing the tethering, well if you are very careful, you can try it. Subcision needles are much thicker and longer than our single needles and they cut the fibers more efficiently but they also cause quite major skin trauma and can cause skin nodules. The subcision needle has sharp edges and the surgeon moves them repetitively back and forth.
You should definitely try to combine it with the suction method. Please read this:
