I have brown acne marks remaining. Can these also be treated with a laser?

I used to think that once the breakouts subsided, it was over, but lately I'm even more stressed because of the remaining marks.

I tend to get fewer new breakouts than before, but the spots where they appeared previously remain as brown spots, making my skin look patchy.

I waited a few months thinking it would naturally fade away, but some parts are still the same as I expected, so now I'm wondering if I should look into laser treatment.

Even if it's acne marks, is the management method different depending on whether they remain red or brown?

I am more concerned about the marks that look brown or grayish rather than red.

I'm wondering if something like this can also fade little by little with a laser haha

Also, since I currently have almost no skin issues, I'm not sure if I should get laser treatment focused on the marks, or if it would be better to wait until my skin is completely stable before starting.

I'm also worried that if I apply too much pressure to get rid of the marks, my skin might become even more sensitive.

I want my skin tone to become naturally even, rather than getting rid of it all at once.

I am also wondering if the marks might temporarily look darker after receiving the laser treatment.

If such a process exists, I would also like to know how long it takes to determine that it has faded.

I've also heard that it can get darker again if you don't protect yourself properly from UV rays, so I should be extra careful with sunscreen than usual while getting laser treatment, right?

For those of you who have been consistently receiving laser treatments for acne marks, did you notice after a few sessions that they were definitely less visible than before?

I'm curious if there was a noticeable difference when comparing photos versus looking in the mirror haha.

For those who started with similar concerns about scarring, please share your actual process.
