Questions regarding the effectiveness of nose blackhead and pore reduction treatments

I am posting this because of the dark blackheads on both sides of my nose and the butterfly zone, as well as enlarged pores.

I've tried using face masks and scrubs at home, but the relief is only temporary, and it feels like my pores are actually getting wider, so now I'm planning to get a dermatological procedure.

I looked it up and found that treatments like Fraxel, Potenza, Pico Laser, and Aqua Peel are widely used for shrinking pores and improving blackheads.

I've heard a lot that it's really difficult to restore pores to their original state even after getting laser treatment,

I am curious about how effective the procedure is when actually performed.

Can I definitely see the effect of blackheads being thoroughly cleansed and enlarged pores being tightened?

Usually, how many sessions in a package are required to make the skin texture smooth,

Also, I am seeking advice from those who have actually experienced whether redness or scarring remains for a long time after the procedure.
