Please recommend a laser treatment for acne scars.

Is it possible to treat acne scars with lasers?

I'm curious which laser is effective for acne scar management.

How long does it take and how many times?

I'm a high school graduate and I have a lot of acne scars and red marks due to academic stress.

I'm worried because my face is red and I have a lot of scars.

Will acne scars return to egg-like skin after treatment?

I want to get acne scar treatment and go to college with clear skin. Is that possible?
