Does anyone know how to get rid of old blackheads I've had for 20-something years?

I've had blackheads on my nose since I was really young.
I've been living with it exactly the same for over 20 years.

I've tried using nose strips and rubbing it with cleansing oil, too.
I've tried all sorts of things that are said to be good for removing blackheads, but

It seemed a bit cleaner for a few days after I did it, but
Eventually, it comes back up black again. I'm seriously going crazy. . ..

(Especially the old blackheads on the sides of my nose really won't budge lol ㅠㅠ)

I've seen a lot of people these days managing their sebum with softeners; would they be effective for removing old blackheads as well?

There is also a saying that it is better to manage it by consistently dissolving it rather than pulling it out completely.
I don't know what to do..🥲

If anyone has successfully removed old blackheads like me
Please tell me how you managed this...
