My nose pores look big, and I'm wondering if it's due to sebum.

Lately, whenever I look in the mirror, I can see the pores on my nose and the sides of it so clearly that it bothers me.

It wasn't that my skin was completely sebum-free before, but recently, the area around my nose becomes shiny shortly after washing my face, and my pores appear to have widened as sebum builds up.

I thought I needed to get rid of sebum to make my pores less visible, so I tried cleansing for a long time or using pore masks, but my skin only looked clean for a short while before returning to its original state.

Actually, the area around my nose sometimes stings or turns white and flaky, so I am worried about whether I should continue. To me, my pores look enlarged due to sebum, but could it be that they are more noticeable due to skin elasticity or dryness?

I am wondering if simply getting extractions is sufficient, or if I need a program that manages both sebum and pores. I would like to consult about treatments that even sensitive skin can start without any concerns.
