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 .
Introduction : Acne scarring is a very common problem , which can be extensive , and may lead to significant psychosocial morbidity .
Multiple types of treatments are used to ameliorate atrophic scars with varying degrees of success .
This paper provides an overview of the various energy-based modalities that are commonly employed against acne scarring .
Objectives and methods : A comprehensive literature search of papers published since 2008 was performed in order to determine the efficacy and adverse reactions of commonly used energy-based treatments against post-acne scarring .
Randomized clinical trial of CO2 LASER pinpoint irradiation technique versus chemical reconstruction of skin scars (CROSS) in treating ice pick acne scars
Abstract Background : Pinpoint irradiation technique CO2 LASER and Chemical Reconstruction Of Skin Scars ( CROSS ) are effective treatments for atrophic acne scars as fractional photothermolysis . Objective : This study was design ed to prospect ively compare the use of a pinpoint irradiation technique versus TCA CROSS in treating ice pick acne scars . Methods : Thirty-two patients with ice pick acne scars were included in this open , label pilot study . Pinpoint irradiation technique by CO2 LASER and TCA CROSS were applied for the study and control group , respectively . Twenty-eight patients with ice pick acne scars were included in this open , label pilot study . They were r and omly assigned to two groups : the first group ( 14 patients ) received pinpoint irradiation by CO2 LASER as a study group , and the second group ( 14 patients ) received TCA CROSS as a control group . In both treatments , there were four sessions at 3-week interval , and 3 months of follow up . Results : There were statistically significant difference in acne scar severity index and qualitative scarring grading system in the improvement results between the study and control groups ( p < 0.05 ) . Conclusion : Pinpoint irradiation technique by CO2 LASER is safe and more effective than TCA CROSS technique . Clinical improvement was achieved in all 14 patients without dramatic adverse effects
