While lasers and topical treatments are frequently used to manage hyperpigmentation, a standardized way of measuring response to treatment is difficult.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aims<\/jats:title><jats:p>The 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.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This 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 <jats:italic>W<\/jats:italic>, Spearman's <jats:italic>\u03c1<\/jats:italic>\/rho, weighted Cohen's kappa, and Bland\u2013Altman analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The 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\u20133 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\u2010friendly, and the majority expressed interest in incorporating it into their practices to document patient conditions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The KHS is an effective and user\u2010friendly tool for evaluating facial hyperpigmentation, addressing a significant need within dermatology.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jocd.70055","type":"journal-article","created":{"date-parts":[[2025,4,1]],"date-time":"2025-04-01T09:13:59Z","timestamp":1743498839000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Kesty Hyperpigmentation Scale: A Study to Validate a New Tool for Assessing Facial Hyperpigmentation"],"prefix":"10.1111","volume":"24","author":[{"given":"Chelsea E.","family":"Kesty","sequence":"first","affiliation":[{"name":"St. Petersburg Skin and Laser  St. Petersburg Florida USA"},{"name":"Kesty AI  St. Petersburg Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarina R.","family":"Kesty","sequence":"additional","affiliation":[{"name":"St. Petersburg Skin and Laser  St. Petersburg Florida USA"},{"name":"Kesty AI  St. Petersburg Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,4]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/dth.14095"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.det.2023.02.005"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.7573\/dic.2021\u201011\u20102"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/bjd.12536"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.2165\/00128071\u2010200001050\u201000001"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.burns.2022.04.017"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10103\u2010020\u201003008\u2010z"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/DSS.0000000000001521"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1524\u20104725.2010.01643.x"},{"issue":"4","key":"e_1_2_10_11_1","first-page":"270","article-title":"The Taylor Hyperpigmentation Scale: A New Visual Assessment Tool for the Evaluation of Skin Color and Pigmentation","volume":"76","author":"Taylor S.
