How should I treat acne scars?

I think acne is really the worst.

When I had acne, my skin would get red and irritated, and it was difficult and a source of worry...

Now that I'm getting less acne, the acne scars are stressing me out.

Hyperpigmentation has developed on the acne-affected areas, and acne scars remain.

It feels like the pigmentation is fading a little over time...

It seems like pitted acne marks and scars don't go away easily.

What should I do about pitted acne scars?

Is laser treatment effective for acne scars?

Is the sooner laser treatment is done, the better the results?

My child is a teenage boy. Is it okay for teenagers to receive laser treatment?

I'm worried about my acne scars.
