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 .

Treatment of acne scars using the plasma skin regeneration (PSR) system.
BACKGROUND AND OBJECTIVES Acne scarring is a common and difficult to treat condition . The plasma skin regeneration ( PSR ) system is a novel device that causes delayed ablation of the epidermis and controlled thermal modification to the underlying dermis . PSR has previously been shown to be a safe and effective treatment for facial rhytides and benign skin lesions . In this study , we investigated the safety and efficacy of single-treatment , high-energy , double-pass PSR for the treatment of acne scarring . STUDY DESIGN / MATERIAL S AND METHODS Ten patients with acne scarring and Fitzpatrick skin types I-III were included in the study . All patients underwent a single PSR treatment with two high-energy passes ( 3.5 - 4.0 J ) . Treatments were performed in an outpatient clinic setting . Nine patients completed 6 months of follow-up . Improvement was determined by patient question naires and physician evaluation of digital photographs taken prior to treatment and at 3 and 6 months post-treatment . RESULTS On average , patients reported 34 % improvement in their acne scarring at 3 months and 33 % improvement at 6 months . Blinded physician ratings of patient photos demonstrated 19 % improvement at 3 months and 34 % at 6 months . Re-epithelialization was complete by 4 - 6 days after treatment , and no serious adverse events were encountered . CONCLUSION PSR appears to provide a safe and effective single treatment , minimal downtime alternative for the treatment of acne scarring . Additional studies are warranted to further demonstrate the safety and efficacy of this device
