Do you know how to get rid of blackheads?

I've been struggling with blackheads since I was a teenager. At first, I was satisfied with the results I saw immediately after squeezing one or two, but at some point, they started to increase in number, and even after squeezing, I didn't feel refreshed. The holes only got bigger, became irritated, and my skin started to get damaged.

But once I start touching them, there are many things that stand out and I can't pretend not to notice them. They say it's important not to touch them as much as possible, but when I look in the mirror after washing my face, and after putting on makeup, I pay too much attention to my nose and cover it up, so I don't like the thick makeup. I'm wondering if I should get it professionally taken care of.

Even if you try cosmetics or products that are said to be good for blackheads, it seems like it only gives the illusion of temporary clearing rather than a noticeable effect.

For example, I bought a volcanic foam cleanser because they said it was good, but I didn't see any results. I saw a home shopping channel say that if you cover it and rub it, the blackheads will melt away, so I bought it, but it had the opposite effect. A nose pack seemed to have the best effect, but everyone advised me against it because it made the situation worse.

I wonder if there was a time when I had a smooth nose without blackheads, but now I feel like I've become an ugly person who is in a hurry to put on thick makeup because I'm not confident in my bare face.

They say that even if you get treatment at a dermatologist, blackheads can never be reversed. Is that true?
