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 .

Do combined alternating sessions of 1540 nm nonablative fractional laser and percutaneous collagen induction with trichloroacetic acid 20% show better results than each individual modality in the treatment of atrophic acne scars? A randomized controlled trial
Background : There have been no well-controlled studies evaluating the efficacy of combining 1540 nm nonablative fractional laser with percutaneous collagen induction ( PCI ) and trichloroacetic acid ( TCA ) 20 % in the treatment of atrophic acne scars . Objective : We hypothesized that combined alternating sessions of both modalities would show better results than each individual modality . Methods and material s : Thirty-nine patients with post acne atrophic scars were included in this study . Patients were r and omly equally divided into three groups ; group 1 was subjected to six sessions of PCI combined with TCA 20 % in the same session , group 2 was subjected to six sessions of 1540 nm fractional laser and group 3 was subjected to combined alternating sessions of the previously mentioned two modalities . Results : Scar severity scores improved by a mean of 59.79 % ( 95 % CI 47.38–72.21 ) ( p < 0.001 ) in group 1 , a mean of 61.83 % ( 95 % CI 54.09–69.56 ) ( p < 0.001 ) in group 2 and a mean of 78.27 % ( 95 % CI 74.39–82.15 ) ( p < 0.001 ) in group 3 . The difference in the degree of improvement was statistically significant when comparing the three groups using ANOVA test ( p = 0.004 ) . Conclusion : The current work recommends combining 1540 nm nonablative fractional laser in alternation with PCI and TCA 20 % in the treatment of atrophic acne scars
