The reason for blackheads that I keep worrying about is...ㅠ

Hello, I'm a man who has become interested in skin care as I've gotten older.

Everything else is fine, but I don't know what's causing the blackheads that are so stuck like black sesame seeds on my nose. I tried removing them with a nose pack or using a blackhead extractor, but they only appear for a short time, and after a few days, they come back in the same black color;;;

They say that men secrete more sebum than women, but to fundamentally solve the cause of blackheads that bother me every time I see them, I think I need to do more than just wash my face diligently.

Why do these blackheads keep recurring? I'm curious about which dermatological treatments are most effective at removing the cause and preventing recurrence. Please advise!
