Discussion : Ablative lasers seem to achieve the highest degree of efficacy , albeit this is associated with significant pain and downtime , and the risk for long-term pigmentary changes .
Non-ablative fractional photothermolysis ( FP ) has a much safer profile but can not achieve as good cosmetic results .
The efficacies of fractional radiofrequency microneedling and radiofrequency are slightly inferior to that of FP but offer an even safer adverse profile .

Comparison of Nonablative Fractional Erbium Laser 1,340 nm and Microneedling for the Treatment of Atrophic Acne Scars: A Randomized Clinical Trial
BACKGROUND The efficacy and safety of nonablative fractional laser for acne scars treatment has been described in several studies . Recently , microneedling treatment has been showing promising results with lower costs , quick healing time , and low risk of postinflammatory hyperpigmentation ( PIH ) . OBJECTIVE To compare the effectiveness and safety of nonablative fractional erbium laser 1,340 nm and microneedling for the treatment of facial atrophic acne scars . METHODS Forty-six patients with atrophic facial acne scars were r and omized to microneedling and laser groups , receiving 3 sessions performed monthly . Two blinded dermatologists applied the vali date d “ Quantitative Global Grading System for Postacne Scarring ” scale , before , 2 months , and 6 months after the treatment . Side effects were recorded at each follow-up visit and patient 's satisfaction was evaluated . RESULTS Both groups showed a significant improvement , and there was no statistically significant difference between results of both therapies ( p = .264 ) . The erythema after each session was longer in the laser group and 13.6 % subjects experienced PIH . No PIH was observed in the microneedling group . CONCLUSION This study shows that both nonablative fractional laser 1,340 nm and microneedling are comparable and effective in the treatment of atrophic acne scars . Microneedling is well tolerated , with fewer side effects and lower down time
