What treatment is effective for acne scars and red marks?

I have some red marks from acne scars.

Once a month, when my period comes around, I get pimples around my chin, and if I squeeze them, I think it causes pigmentation.

As I get older, I feel like my skin is taking longer to heal. Scars and red marks last longer.

Please recommend a laser or skin booster that is effective on red marks from acne scars.

I wonder if such a procedure would also help with acne management.
