Ablative fractional erbium-doped yttrium aluminum garnet laser with coagulation mode for the treatment of atrophic acne scars in Asian skin.

Background: The introduction of fractional photothermolysis (FP) for the treatment of atrophic acne scars has been proven to provide satisfactory results. For severe atrophic acne scarring, nonablative FP achieves fair improvement and takes multiple treatment sessions. Ablative fractional resurfacing provides an alternative modality with greater satisfaction.
