I'm curious about the actual feel of laser toning or resurfacing.

I have a few acne scars and blemishes on my face.
I'm thinking about getting laser treatment.
I looked it up and it says there is toning and resurfacing.
I'm not an expert, I just looked up some information.
I can't tell what the difference is.

How long is the swelling or the recovery period?
I'm also curious about the frequency and cost.
If there is anyone who has actually received it or has experience with it,
Please share your honest review or feelings.
Personally, I'd be curious if you have any tips on choosing the right treatment for your skin.
