Abstract
Context:Though many treatment options are available for treating post-acne scars, optimized treatment still does not exist. Till date, comparative split-face studies, analyzing the efficacy of combined treatment modalities for acne scars with adequate sample size and with statistically significant results, are still lacking.Aim:The aim of this study was to compare the effectiveness of the combined use of platelet-rich plasma (PRP) and fractional ablative CO2 laser (FACL) versus FACL in the management of acne scars and to study the safety of autologous PRP and FACL in the treatment of post-acne scars.Settings and Design:This was a randomized split-face trial study.Materials and Methods:This study was conducted in 30 patients having Goodman and Baron’s grade 3 and 4 acne scars. The efficacy of PRP in combination with FACL was compared to FACL alone in the treatment of post-acne scars. Right half of the patient’s face was taken as the study side where FACL was performed followed by PRP injections. The left half of the same patient’s face was taken as the control side where FACL was performed followed by normal saline injections.Statistical Analysis:Results were analyzed using Statistical Package for the Social Sciences (SPSS, Chicago).Results:At the time of enrollment, mean Goodman and Baron Acne Qualitative Grading Scale on study and control side was 3.80 with standard deviation (SD) of 0.40 at baseline. After completion of four treatment sessions, it was reduced to 2.43 (SD = 0.76) and 2.76 (SD = 0.49) on the study and control side, respectively. Improvement on both sides was statistically significant (P = 0.000).Conclusion:There is no single proven modality for the effective treatment of post-acne scars. Combination of FACL with newer adjuvants such as PRP has definitive role in managing post-acne scars with better safety profile than FACL alone.
