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 a Fractional Microplasma Radio Frequency Technology and Carbon Dioxide Fractional Laser for the Treatment of Atrophic Acne Scars: A Randomized Split‐Face Clinical Study
BACKGROUND No studies have compared fractional microplasma radio frequency ( RF ) technology with the carbon dioxide fractional laser system ( CO2 FS ) in the treatment of atrophic acne scars in the same patient . OBJECTIVE To compare the efficacy and safety of fractional microplasma RF with CO2 FS in the treatment of atrophic acne scars . METHODS AND MATERIAL S Thirty‐three Asian patients received three sessions of a r and omized split‐face treatment of fractional microplasma RF or CO2 FS . RESULTS Both modalities had a roughly equivalent effect . Échelle d'Évaluation Clinique Des Cicatrices d'Acné scores were significantly lower after fractional microplasma RF ( from 51.1 ± 14.2 to 22.3 ± 8.6 , 56.4 % improvement ) and CO2 FS ( from 48.8 ± 15.1 to 19.9 ± 7.9 , 59.2 % improvement ) treatments . There was no statistically significant difference between the two therapies . Twelve subjects ( 36.4 % ) experienced postinflammatory hyperpigmentation ( PIH ) after 30 of 99 treatment sessions ( 30.3 % ) on the CO2 FS side and no PIH was observed on the fractional microplasma RF sides . CONCLUSION Both modalities have good effects on treating atrophic scars . PIH was not seen with the fractional microplasma RF , which might make it a better choice for patients with darker skin
