What is the best way to get rid of and manage blackheads?

I usually squeeze them with my hands or use nose strips to get rid of blackheads.

But I heard that squeezing it with your hands is actually bad because germs and bacteria can get in.

Even if I use a nose pack, it is only temporary and comes back after a while.

I heard that dermatologists can get rid of blackheads... but it probably isn't permanent, right?

Even if you get rid of blackheads, you need to take good care of your skin so they don't get worse.
