It could possibly be rosacea. I had always had problems with the redness appearing on my cheeks and nose, but when I started to get little red bumps on my nose (like yours with no puss in them) that didn't go away, that's what got me motivated to visit my dermatologist and I was diagnosed with rosacea.
The good news is that the Metrolotion made the bumps go away completely and quickly!

I still get the redness in the cheeks, but the lotion seems to be helping and I am going to see if, with time it will help lessen or eliminate the redness (although it may never fully go away, just control it, as Rosacea is a chronic condition).
I would have a dermatologist check you out, just to be sure and to prevent them from getting worse.
Here are some links about Rosacea that I posted on that original thread that you saw, in case you missed them...
