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 .
Conclusion : Multiple devices have been used with varying levels of efficacy and very different safety profiles .
There is an overall lack of high- quality evidence about the effects of different interventions .

Clinical evaluation of the efficacy and safety of fractional bipolar radiofrequency for the treatment of moderate to severe acne scars
Several treatment modalities are used for the treatment of acne scars with variable results . Recent studies showed that fractional radiofrequency may be an effective treatment modality for acne scars . The objective of this study was to assess the efficacy , safety , tolerability and patient satisfaction of fractional bipolar radiofrequency ( RF ) , the eTwo ™ system ( Syneron C and ela Ltd. , Yokneam , Israel ) for treating acne scars . Twelve patients with moderate to severe acne scars received 3–5 treatments with the Sublative fractionated bipolar RF applicator of the eTwo device at 1‐month intervals . Patients were evaluated clinical ly and photographically at each visit and 3 months after the final treatment . Very good improvement ( at least one scale ) was seen after completing the five treatments . The patient satisfaction survey ( Global Aesthetic Improvement Scale scores ) revealed that half ( 6 out of 12 ) of the patients reported to be satisfied with treatment results , while the other half reported to be very satisfied . Beyond the expected erythema and minimal scab formation in the treated areas , which was mild and transient , none of the participants reported any adverse events . The data presented here support the high efficacy and safety of fractionated bipolar RF for the aesthetic improvement of moderate to severe acne  scars
