Small puncture pokes that close up quick and you don't see due to the swelling. Also with fat grafting, they make the small puncture poke to introduce the cannula and they close up quickly.
That's exactly what happened, I didn't really notice them as the whole area was swollen and bruised, and by the time bruising disappeared, they closed up. I cannot see or feel them at all now. Anyway, interesting to know that someone pushed a bunch of metal screws through my skin from the outside
