NOTICEABLE ZIT WHAT DO I DO?!?

I have this really noticeable zit which is near my nostril but not completely in it. It isn't big but it is VERY noticeable. It is all white which I think means there is puss in it. Is there a certain way I can pop it so it isn't noticeable? I've tried covering it up but nothing is working. I've only had it for 2 days but what do i do? Should I clean it? I have no idea!
