Subdermal Laser-Assisted Scar Subcision (SLASS) Combined With Fractional CO
Article in Journal of cosmetic dermatology, 2025. 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
backgroundRolling atrophic acne scars attach the deeper dermis to the muscular-fascial layer with a fibrous component. Subcision is the most commonly used treatment technique for rolling scars.
aimsOur objective is to describe the efficacy and safety profile of a new type of subcision: the "subdermal laser-assisted scar subcision" (SLASS), using a 1470-nm diode fiber laser in combination with ablative fractional CO PATIENTS/
methodsA retrospective study of the combination of subcision with subdermal laser and CO
resultsMean reduction of the ECCA grade scale before and after treatment was of 92.6 ± 34.3 points (p < 0.05). Considering SCAR-S scale, ranging from 0 to 5 (0 = clear; 5 = very severe), a mean improvement of 1.67 points was obtained (p < 0.05). Significant differences were found in both ECCA scale and SCAR-S scale before and after treatment. None of the patients had severe adverse effects after the procedure.
conclusionsSLASS subcision can be considered as a promising technique for rolling acne scars. It provides a thermo-mechanical subcision effect to the scarred area compared with traditional subcision techniques. CO
