The Kesty Hyperpigmentation Scale: A Study to Validate a New Tool for Assessing Facial Hyperpigmentation.
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. Cited by 1 paper.
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
backgroundFacial hyperpigmentation due to sun damage, post-inflammatory hyperpigmentation, and other factors is a common complaint of patients. While lasers and topical treatments are frequently used to manage hyperpigmentation, a standardized way of measuring response to treatment is difficult.
aimsThe Kesty Hyperpigmentation Scale (KHS) is a novel clinical instrument created to provide a consistent approach for evaluating facial hyperpigmentation in both cosmetic dermatology and broader medical settings.
methodsThis study introduces the KHS, describes the process of its creation and validation, and examines its practical uses in clinical settings. Statistical analysis included Gwet's AC2, Kendall's W, Spearman's ρ/rho, weighted Cohen's kappa, and Bland-Altman analysis.
resultsThe findings of the statistical analysis included high ordinal agreement, strong rank concordance, and minimal bias. This supports the conclusion that the novel rating approach is both reliable and valid for assessing skin hyperpigmentation on the given 0-3 scale. The KHS offers an objective framework to measure the severity of hyperpigmentation, helping clinicians track patient progress after cosmetic treatments, and fostering improved communication with patients. Participants in this study found the scale to be user-friendly, and the majority expressed interest in incorporating it into their practices to document patient conditions.
conclusionsThe KHS is an effective and user-friendly tool for evaluating facial hyperpigmentation, addressing a significant need within dermatology.
