If I were to do just one skincare treatment before my vacation, which procedure would you recommend?

My budget isn't very generous, so it's difficult for me to get a variety of treatments; I'm planning to try just one procedure. My skin concerns include enlarged pores, a slightly rough texture, and a dull complexion, so it is really hard to choose just one.

When I search online, some people say Rejuran is good, others say laser toning is decent, and many say skin boosters have high satisfaction, which makes me even more confused. Since every clinic recommends different things, I don't know what criteria to use to make a choice.

I have about 2 to 3 weeks left until my vacation, and the most important thing is for my skin to look clear in photos. I'm not looking for a dramatic transformation; it would be enough if my makeup applied well and my skin looked in good condition. If anyone has actually received treatments before their vacation and has any procedures they highly recommend, please let me know why; it would be really helpful.
