How long do the effects of the pore treatment last?!!

Lately, every time I look in the mirror, I'm so self-conscious about the pores on the sides of my nose and cheeks that it's seriously stressing me out. ㅠㅠㅠ Before, I just thought my skin was a bit rough, but lately, when I apply makeup, the foundation feels like it's settling into my pores so badly that it really upsets me. They're especially visible in brightly lit places, so I get self-conscious about people staring at me too, lol. So, I finally started looking into pore treatments!!

But there are so many types of pore treatments, more than I expected. Fraxel, Potenza, PicoFraxel, Rejuran, and so on—since everyone says they're good, it actually makes me more confused. I don't know which treatment is right for me, and I'm wondering if I can see results after just one session. I also want to know how many sessions are usually required to see noticeable changes.

And what I'm most curious about is how long the effects of the pore treatment last!! Since I'm spending money on it, I'd be so sad if the results went back to how they were quickly ㅠㅠㅠ I'm wondering how many months the effects last after the treatment, and if they last longer if I take good care of it. Please share your honest reviews if you've actually had the treatment~~
