Eli5 why do tattoo machines not cut your skin?

Question

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?

Answer 1

It does cut the skin, although pierces might be more precisely accurate. It breaks the skin and injects ink underneath
