Do I need to apply pore ampoules consistently for them to be effective?

My biggest skin concern is definitely the issue with my pores. Lately, pore pigmentation has become particularly noticeable, making my skin look dull. It is very stressful because even pore cushions don't provide perfect coverage when I apply makeup. I have been looking for ways to minimize pores, but I am confused by the sheer number of products available. I have heard that using pore pads to remove dead skin cells and sebum, followed by a pore ampoule or serum, is effective. I am curious to know what differences those who have actually tried this have noticed. Also, would using a pore pack help alleviate pigmentation? I want to establish a proper pore care routine, so I would appreciate advice from those with experience.
