How to professionally say "Get out of my face"?

"Get the fuck out of here!"

and if that doesn't help u make it clear with : "NOW!"

"In case you are wondering about personal space: Sometimes people can get too close to one another. Most people find this disturbing, annoying, and it can affect angry responses. In fact, you are now in my personal space, and thats not something I find helpfull, or relaxing. Care to take a couple steps back? maybe continue this conversation later?"

@magicMirror the OP said 'professionally', not polite, but ok we will accept that too =)
