Maybe, it's different for everyone I think.
You say you're healed after 2 days. For me, it takes 4-5 days to heal, the first few days it hurts a bit if I try to comb. But I'm also doing 2mm at the fastest setting with a pen.
Edit: Also have itch after needling
Takes about three days for my skin to to heal at 2.5mm, strange that you get an itch though, i haven't experienced anything like that, or the flakes some people have mentioned.
