How to manage pore pigmentation

Just thinking about having poreless skin makes me envious.

That said, I don't think I've really done any special pore care... I should take this as an opportunity to pay more attention to my pores.

One day in my 30s, a dark spot started appearing in the middle of my cheek. I thought it was a mole and had it removed at a dermatologist's office once or twice, but it kept coming back. Now it's just in the early stages, but suddenly I started wondering if it might be pore hyperpigmentation. I'm also curious why pore hyperpigmentation occurs.

Are there any good cosmetics or care methods for pore pigmentation?

I'd love to hear some great tips from those who have successfully managed pore pigmentation.
