Treatment of Acne Scarring Using a Dual-Spot-Size Ablative Fractionated Carbon Dioxide Laser: Review of the Literature

BACKGROUND
Fractional photothermolysis has been reported in the literature to improve pigmentary and textural changes associated with acne scarring.


OBJECTIVE
To review the literature for the treatment of acne scarring using nonablative fractional laser (NAFL) and ablative fractional laser (AFL) resurfacing.


METHODS
Review of the Medline literature evaluating NAFL and AFL for acne scarring.
