I have never heard of this technique before, is it fairly new? Is ther an official name for it so I can read about it online.Thanks
Sorry--that is how the neph explained the healing of the skin. Otherwise, you would be piercing the skin each time you did a stick and then why would you bother having a buttonhole? It creates a tunnel that the needle can slide through. Comparing it was just a quick visual to understand how the skin heals.
