Even if I wash my face thoroughly, the pores on my nose and cheeks don't look clean.

I am wondering what I should check when the pores around my nose or cheeks do not look clean even after washing my face. I tend to pay a little more attention to cleansing on days when I wear makeup, but sometimes it looks like sebum remains inside my pores even immediately after washing. However, if I keep washing or rubbing, my skin can become dry, so I am concerned about how far I should go with my skincare routine.

Is it difficult to completely remove visible sebum from pores with cleansing alone? I’ve heard that it is important to use a cleansing method suited to my skin condition rather than washing more harshly, but I’m not sure what criteria I should use to choose a product.

If a dermatologist checks the condition of my pores and sebum, can they distinguish whether the sebum simply appears normal or if it requires separate extraction or care? I am wondering if it is acceptable to consult about both concerns together, especially if sebum is clearly visible around the nose and there are small bumps on the cheeks. I would also like to know about cleansing methods that do not over-irritate the skin and the recommended care frequency.
