What treatments are effective for improving acne marks?

My acne has almost completely cleared up, but the problem is that the marks linger for a long time. In particular, the red marks around my cheeks persist, so they don't cover well even with makeup, and my skin looks messy overall.

I thought they would naturally fade over time, but since there hasn't been much change even after several months, I am considering getting a procedure. I looked it up and it seems there are lasers and various other skin treatments available, but I'm not sure which one is most suitable for acne marks.

Please let me know if there is a treatment at Maypure that is highly recommended for improving acne marks. I am also curious if the procedure helps reduce redness and how many sessions are required to see results. Since my skin tends to be sensitive, I would prefer a treatment that is not too irritating, and I would like to hear the experiences of those who have undergone treatments with similar concerns.
