Efficacy and Safety of Plasma Radiofrequency Combined With Topical Tranexamic Acid for Early Post-Traumatic Scars With Hyperpigmentation: A Retrospective Study.
Article in Journal of cosmetic dermatology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTreatment of early post-traumatic scars with energy-based devices like plasma radiofrequency is often complicated by post-inflammatory hyperpigmentation (PIH). This study aimed to evaluate the efficacy and safety of a combination regimen of plasma radiofrequency and immediate topical application of tranexamic acid (TXA) to simultaneously address both scars and concomitant PIH.
methodsThis retrospective study included 35 patients with early post-traumatic scars and hyperpigmentation. All patients underwent three sessions of plasma radiofrequency at 6-week intervals, each followed by immediate in-office and 7-day at-home topical application of TXA. Efficacy was evaluated using the Modified Vancouver Scar Scale (mVSS), Investigator's Global Assessment (IGA), and a patient-reported Visual Analogue Scale (VAS) for satisfaction at baseline and 6 weeks after the final session.
resultsSignificant improvements were observed in all patients. The mean mVSS score decreased from a baseline of 5.71 ± 1.47 to 2.66 ± 2.07 at the final follow-up (p < 0.001). According to IGA, 91.4% (32/35) of patients achieved moderate to excellent improvement. High patient satisfaction was reported on the VAS. No serious adverse events were observed; side effects were limited to transient erythema and edema.
conclusionThe combination of plasma radiofrequency with immediate topical TXA application is a safe and effective strategy for treating early scars with hyperpigmentation. This dual-action approach successfully improves scar characteristics while controlling and reversing pigmentation, offering a valuable therapeutic option to optimize outcomes with energy-based devices.
