A comparative study of combined Microneedling Fractional Radiofrequency and Platelet-Rich Plasma versus Microneedling Fractional Radiofrequency alone in atrophic acne scars and effect of treatment on quality of life


P Chowdhary, M Kaur, A Jagati, H Tiwari


Microneedling Fractional Radiofrequency (MFR) is a newer, well-accepted modality for the treatment of atrophic acne scars while the role of Platelet rich plasma (PRP) remains to be investigated. The aim of this study was to compare the efficacy of combined MFR and PRP therapy (group A) with microneedling fractional radiofrequency alone (group B) in facial atrophic acne scars and effect of treatment on quality of life. Statistical comparison of end results between group A and B were found to be equally effective, based on GBS scale and Observer's scar assessment. However, overall scar assessment by patient and Dermatology Life Quality Index was better in patients of group A.
