Keeping the face clean is ideal, of course, but a mild hydrocortisone cream can help dry up the pimple, but can also help remove the redness which, of course, makes it less obvious.
I've had nose pimples right at the edge of my nostril where it meets my face. Those are the worst. They just sit there and hurt. I've been known to put a hot compress on those, hoping to bring it to a "head" so it will pop. Yeah, yeah, conventional wisdom says don't pop them, but those painful nose pimples on the side sometimes won't stop hurting until they pop, either by themselves or with help.
