However, limited data exist on the long-term effects of NB-UVB-induced repigmentation. This study evaluated the long-term durability of repigmentation achieved through NB-UVB phototherapy for up to 1 year in 176 patients with non-segmental vitiligo. Demographic and clinical variables, including age, gender, skin phototype, body site involvement, treatment duration, cumulative radiation dose, and clinically significant repigmentation response, were collected. Clinically significant repigmentation was defined as \u2265\u200950% repigmentation of vitiligo-affected areas, while a durable response was repigmentation lasting \u2265\u20096 months post-treatment. Of the 176 patients, 80 (45%) achieved clinically significant repigmentation, with the highest success rates observed in the face and neck region (53%). Among responders, 76 (95%) patients maintained their response for \u2265\u20096 months post-treatment discontinuation, and 47 (59%) sustained repigmentation for &gt;\u200972 months. Additionally, \u2265\u200950% repigmentation, longer treatment duration (&gt;\u200918 months), and higher cumulative radiation dose (&gt;\u2009356 J\/cm\u00b2) were associated with a durable repigmentation response. NB-UVB phototherapy provides lasting repigmentation in non-segmental vitiligo, with many patients maintaining results for &gt;\u20096 years. Clinically significant response post-NB-UVB phototherapy, prolonged treatment duration, and cumulative radiation dose are key factors associated with long-term repigmentation.<\/jats:p>","DOI":"10.2340\/actadv.v105.43690","type":"journal-article","created":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T08:40:02Z","timestamp":1758616802000},"page":"adv43690","source":"Crossref","is-referenced-by-count":1,"title":["Long-term Durability of Narrowband Ultraviolet B-induced Repigmentation in Non-segmental Vitiligo: A Retrospective Study"],"prefix":"10.2340","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2964-7417","authenticated-orcid":false,"given":"Riad","family":"Kassem","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilya","family":"Vaynshteyn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aviv","family":"Barzilai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Assaf","family":"Handelsman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alon","family":"Scope","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moshe","family":"Schaffer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon","family":"Baum","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"Pavlotsky","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2025,9,23]]},"reference":[{"key":"127313","unstructured":"Monem El Mofty A.
