[Misc] do you guys ever intentionally not treat a spot to try prevent it getting bigger/coming to head before a big event?

Got a date tomorrow and there's a spot under the skin that's noticeable but not hideous, it's raised more like a bump than a spot and slightly red atm. I'd do a hot compress but I'm afraid it'll come to head tomorrow if I do. What can I do to just settle it rather than treat it?
