How long does an acne scar treatment usually take?

I have a few pitted scars on my cheeks from messing with my acne back in school. It has been a lifelong complex for me, but I would like to take this opportunity to make them smooth through an acne scar treatment. I am planning to visit over the weekend.

I'm wondering how long an acne scar treatment usually takes. I should allow plenty of time, including the time to apply the numbing cream, right? I'm also curious if I can drive home immediately after the treatment.

Acne has always held me back, so I hope to be completely free from it this time.

This time, I’m really determined to be reborn with clear skin. I’d appreciate some advice from those of you with experience!
