Is there a limit to how much pore cushions can cover large pores?

Lately, I have been very concerned because my skin has become generally rough and I have noticed my pores getting progressively wider. In particular, even when I apply makeup, pore cushions don't provide smooth coverage, and my pores become even more prominent over time, which is very stressful. While looking for ways to shrink my pores, I came across posts suggesting that using pore pads, a pore serum, and a pore ampoule together is beneficial. I am curious if there is actually a significant difference. Also, since I have developed pore hyperpigmentation, I feel I need a routine that helps improve pigmentation as well, rather than just managing my pores. What product combination would be effective in this situation? I am also unsure if using a pore mask in conjunction with this would help speed up improvement or if it might actually cause irritation. I would appreciate advice from those with experience.
