Does pore crumb really help shrink pores?

My biggest concern regarding skincare these days is my pores. Sebum tends to rise to the surface, making them look wider, and I am very worried that this might even lead to hyperpigmentation. So, I searched for ways to shrink pores and saw many posts suggesting that exfoliating with pore pads and using a pore serum or ampoule together is beneficial. I am curious if this is actually effective. I also heard that combining this with a pore mask can lead to faster improvement, but is it okay to use it only once or twice a week? I am also concerned that using too many different products might actually irritate my skin. If anyone has successfully managed their pores, I would really appreciate it if you could share your personal routines or any products you would highly recommend.
