Where should I start with skincare to address concerns about pores, sebum, and skin tone?

I am writing to inquire because I am concerned about enlarged pores, excess sebum, and a dull skin tone around my nose and cheeks. Looking at the attached photo, sebum is noticeable and pores are clearly visible on my nose and the sides, whereas my cheeks look dry and dull, making my entire face look unkempt.

My nose gets oily over time, and my cheeks feel tight after washing my face, so I'm not sure if managing them with just one method is okay. When I apply makeup, the base settles around my nose, my cheeks look dry and flaky, and my skin tone looks even more uneven.

At home, I tried washing my face, moisturizing, and using a pore mask, but it only looked good for a moment and didn't show any significant changes.

In this case, should I manage sebum and pores first and then address skin tone? Or is there a treatment that can address all three concerns simultaneously? I would like to consult on the priority areas of my current skin and the appropriate order of care.
