Eli5 why do tattoo machines not cut your skin?

413 views

I see it all the time in videos. The tattoo artist pulls a line on the skin, but the needle part needs to be deep into the skin to deposit the ink, so how does it keep pulling the line without cutting the skin?

It is possible to cut for a variety of reasons. Like if the machine is running too fast, running the same area too many times or barbed needles.
There’s actually a scarification method that uses tattoo machines to scar the skin.

But it wouldn’t happen if the artist is half decent. And no. Tattoo needles don’t cut. They puncture/pierce.

On a side note. Catheter needles and piercing needles/blades do actually cut rather than pierce.
