hand tattoos at 20?

I would loooove to get small hand tattoos like this, i don‘t know if the left hand (with the dots) actually counts as fine line? I really am not worried career wise, because I‘m planning on working in a creative field, maybe even as a tattoo artist. I‘m more concerned about how quickly they‘ll fade - should i get thicker lines than in the pic or would that just bleed even more? Also, how do you heal tattoos like that? I work with kids so I can‘t really not wash my hands a lot or not use my hands for two weeks
