I know 2 Jewish girls with nose jobs (and probably other things). How is it not mutilation or doing with the body what one pleases to do these things while a different set of standards applies to tattoos?

That’s stretch . .

How so? The poster to whom I was responding said, “Its forbidden for Jews to tatoo their bodies. The body is not one’s to do with as one pleases. It belongs to G-d and the Jew inhabits it on temporary loan from G-d. One must act holy, be seen as holy and imitate G-d.” If the body is a lease, so to speak, then it ought not be tampered with.

If the nose job was purely aesthetic, then it would probably not be Kosher. However, if it was done to repair an injury or for a medical purpose, it would be fine.
For instance, I've broken my nose 3 times and it negative affects breathing. Getting my nose fixed would be fine. I just keep delaying the surgery.
