What treatment is best for wide and enlarged pores?

Lately, I've noticed my pores in the butterfly zone have widened significantly, and it stresses me out every time I look in the mirror. Home care alone isn't solving the problem, though. Even when I try to cover them up with makeup, the residue just gets stuck in the pores, so I am considering treatments for skin elasticity or pore tightening.
Procedures like PicoFraxel are quite popular. If I actually get the treatment, how much pain is involved and how long does the recovery period take?

Can enlarged pores be completely resolved with a procedure alone?
Although the effects may vary from person to person, I am curious about how many sessions are usually needed to see results and how to care for the skin after the procedure.
