UVB is radiation that is in the region of the ultraviolet spectrum which extends from about 290 to 320\u2009nm in wavelength and that is primarily responsible for sunburn, ageing of the skin, and the development of skin cancer. Thus, since April 2009, the Bureau Interprofessionnel d'Etudes Analytiques (BIPEA) set up a proficiency testing scheme (PTS) for the determination of SPF in\u00a0vivo of sunscreen products according to ISO 24444 standard [Cosmetics \u2010 Sun protection test methods \u2010 <jats:italic>in vivo<\/jats:italic> determination of the sun protection factor (SPF)] to evaluate the analytical performances of laboratories on these analyses. This PTS gathers twenty\u2010six laboratories around the world with one trial a year. For each test, the statistical treatment of the data is performed according to ISO 13528 standard [Statistical methods for use in proficiency testing by interlaboratory comparison]. The assigned and tolerance values are calculated from the participants' data and the performances of the laboratories are evaluated individually and collectively according to ISO 17043 standard [Conformity assessment \u2010 General requirements for proficiency testing]. This paper presents the design of the PT program, its development, and an attentive analysis of laboratories results, which highlight the global performances obtained by laboratories on this type of analysis. The evaluation of the results shows, in fact, a relatively constant dispersion of data since the implementation of the PT program (variability between 10% and 50%).<\/jats:p>","DOI":"10.1111\/ics.13007","type":"journal-article","created":{"date-parts":[[2024,7,25]],"date-time":"2024-07-25T09:19:14Z","timestamp":1721899154000},"page":"1097-1104","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Overview of proficiency testing results for the in\u00a0vivo determination of sun protection factor"],"prefix":"10.1111","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-5683-8728","authenticated-orcid":false,"given":"Djigo\u2010Isett","family":"Zago","sequence":"first","affiliation":[{"name":"BIPEA  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Souad","family":"Ben Bari","sequence":"additional","affiliation":[{"name":"BIPEA  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne","family":"Tirard","sequence":"additional","affiliation":[{"name":"BIPEA  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9bastien","family":"Miksa","sequence":"additional","affiliation":[{"name":"WENEOS  Creil France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pascale","family":"Renoux","sequence":"additional","affiliation":[{"name":"L'OREAL  Chevilly\u2010Larue France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emmanuel","family":"Questel","sequence":"additional","affiliation":[{"name":"Pierre\u2010Fabre  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,7,25]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-4632.2010.04474.x"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2006.08.039"},{"key":"e_1_2_6_4_1","unstructured":"International standard.ISO\/IEC 17043:2023 \u2010 Conformity assessment \u2010 General requirements for proficiency testing."},{"key":"e_1_2_6_5_1","unstructured":"International standard.ISO 24444:2010 \u2010 Cosmetics \u2010 Sun protection test methods \u2010in vivodetermination of the sun protection factor (SPF)."},{"key":"e_1_2_6_6_1","unstructured":"International standard.ISO 13528:2022 \u2010 Statistical methods for use in proficiency testing by interlaboratory comparison."},{"key":"e_1_2_6_7_1","unstructured":"International standard.ISO 24444:2019 \u2010 Cosmetics \u2010 Sun protection test methods \u2010 in\u00a0vivo determination of the sun protection factor (SPF)."},{"key":"e_1_2_6_8_1","unstructured":"International standard.ISO\/IEC 17025:2005 \u2013 General requirements for the competence of testing and calibration laboratories."}],"container-title":["International Journal of Cosmetic Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/ics.13007","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,11,11]],"date-time":"2024-11-11T02:58:22Z","timestamp":1731293902000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/ics.13007"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,7,25]]},"references-count":7,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2024,12]]}},"alternative-id":["10.1111\/ics.13007"],"URL":"https:\/\/doi.org\/10.1111\/ics.13007","archive":["Portico"],"relation":{},"ISSN":["0142-5463","1468-2494"],"issn-type":[{"value":"0142-5463","type":"print"},{"value":"1468-2494","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,7,25]]},"assertion":[{"value":"2024-04-08","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-03","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-25","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
