Laser, Intense Pulsed Light, and Radiofrequency for the Treatment of Burn Scarring: A Systematic Review and Meta-Analysis

Burns and scarring are considered some of the greatest problems in public health because of their frequent occurrence. Today, photo-electric technology shows promising results in the treatment of burn scars. Over the years, more clinical trials and more technologies for scarring have emerged. The aim of this study was to determine better timing and methods of photo-electric therapy for burn scars. This study was registered in PROSPERO (CRD42023397244), following the PRISMA statement, and was carried out in concordance with the PRISMA checklist. In October 2022, we searched PubMed.gov, Embase, and the Cochrane library (1980-present) for published studies related to the photo-electric treatment of burn scars. Two review authors independently selected the studies, extracted the data, assessed the risk of bias among the studies included, and carried out NIH assessments to assess the certainty of the evidence. A third review author arbitrated any disagreements. Our research included 39 studies. We found evidence suggesting that photo-electric therapy between six months and one year offers significantly better outcomes than treatment of scarring after one year. The evidence also suggests the use of IPL for the treatment of early burn scarring. However, it is important to emphasize that the scientific evidence remains insufficient. We need more clinical trials of higher quality and with less heterogeneity to confirm our results.
