I keep getting blackheads on my nose. Is there a treatment method?

I am incredibly stressed out because of the blackheads around my nose. I wash my face thoroughly and even use nose strips occasionally, but while it seems to get clean for a while, the black dots reappear after a few days. It looks like sebum is lodged right up to the sides of my nostrils, to the point where I hate looking in the mirror up close. Squeezing with my fingers does release the sebum, but it feels like it makes my pores bigger, so I am trying not to touch them directly anymore.

Are blackheads caused simply by excessive sebum production? Or do dead skin cells accumulated inside the pores also play a role? Besides treatments like extraction and aqua peels, are there any specific laser treatments effective for blackheads available at dermatology clinics?

I would like to know if consistent treatment lengthens the interval between blackhead recurrences, and how often I should typically receive treatment. I would appreciate the opinions of hospital staff on what treatment would be suitable for managing sebum on the nose without widening the pores.
