What is Microdermabrasion, how much does it cost, and will it get rid of acne scars well? ?

Please explain it to me. I need a solution for my acne scars! Thanks!|||Microdermabrasion may work on very light scars, but if the scars are indented to deeply you would probably have to have a more dramatic laser treatment like the Fraxel. The cost depends on the size of area you are having done, can be any where from $300 for small areas to $900.00 for the full face. per treatment.|||takes an hour, cost ranges from 100-200,
