Effectiveness and Safety of the Use of 1470 nm Laser Therapy in Patients Suffering From Acne Scarring of the Facial Skin.
Article in Clinical, cosmetic and investigational dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Purpose: This prospective, single-center, open-label study aimed to evaluate the efficacy and safety of 1470 nm non-ablative laser therapy in treating facial acne scars. The primary objective was to assess improvements in skin texture, elasticity, and scar depth and diameter, while confirming the absence of significant adverse effects. Patients and Methods: 40 healthy female volunteers aged 18 to 42 years with facial acne scars underwent three sessions of 1470 nm laser therapy at two-week intervals. Outcome measures included cutometric assessments, high-frequency ultrasound evaluations, and clinical photographic documentation, conducted at baseline and on days 21, 42, 70, and 130 post-treatment. Results: Significant improvements were observed across all evaluated parameters. Skin elasticity increased progressively from baseline (mean: 62.95, SD=4.0) to day 21 (63.72, SD=3.8, +4%), day 42 (67.11, SD=4.0, +6%), day 70 (69.08, SD=4.2, +11%), and day 130 (70.80, SD=4.4, +14%; p<0.001). High-frequency ultrasound measurements revealed substantial reductions in scar depth, which decreased by 5% at day 21 (mean: 0.18 mm, SD=0.05, p<0.001), 20% at day 42 (0.15 mm, SD=0.055, p<0.001), 48% at day 70 (0.10 mm, SD=0.06, p<0.001), and 63% at day 130 (0.07 mm, SD=0.065, p<0.001). Scar diameter followed a similar trend, with reductions of 16% at day 21 (3.08 mm, SD=0.3, p<0.001), 26% at day 42 (2.71 mm, SD=0.34, p<0.001), 42% at day 70 (2.13 mm, SD=0.36, p<0.001), and 62% at day 130 (1.39 mm, SD=0.38, p<0.001). Clinical photographic evaluations corroborated these quantitative findings, showing visible improvements in scar appearance and overall skin texture. No adverse events were reported throughout the study. Conclusion: The 1470 nm non-ablative laser therapy demonstrated high efficacy and safety in the treatment of acne scars, delivering substantial therapeutic benefits and high patient satisfaction, offering a valuable therapeutic option for addressing both pigmentation and textural issues associated with acne scars.
