The objective here was to compare the ultraviolet (<jats:styled-content style=\"fixed-case\">UV<\/jats:styled-content>) exposure resulting from a 2\u2010week vacation spent sunbathing with sunscreen\u2010protected skin, with that from a typical course of 10 sessions on a sunbed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A numerical analysis combining data on sunlight and sunbed <jats:styled-content style=\"fixed-case\">UV<\/jats:styled-content> levels, time spent tanning and spectral absorption properties of different types of sunscreen.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The analysis showed that unless a sunscreen provides optimal broad\u2010spectrum\u00a0protection, a 2\u2010week sunbathing vacation that avoids sunburn on sunscreen\u2010protected skin can result in a higher cumulative <jats:styled-content style=\"fixed-case\">UV<\/jats:styled-content> exposure than a typical 10\u2010session sunbed course. The lowest exposures for a given sun protection factor (<jats:styled-content style=\"fixed-case\">SPF<\/jats:styled-content>) are obtained when sunscreen delivers broad\u2010spectrum protection that approaches the ideal of uniform absorption at all wavelengths throughout the <jats:styled-content style=\"fixed-case\">UV<\/jats:styled-content> spectrum.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In extreme cases of recreational sun exposure where sunscreens providing suboptimal broad\u2010spectrum protection are used, the <jats:styled-content style=\"fixed-case\">UV<\/jats:styled-content> insult to the skin is likely to result in higher cumulative exposures than commonly employed sunbed practices.<\/jats:p><\/jats:sec>","DOI":"10.1111\/phpp.12190","type":"journal-article","created":{"date-parts":[[2015,7,3]],"date-time":"2015-07-03T16:02:36Z","timestamp":1435939356000},"page":"307-314","source":"Crossref","is-referenced-by-count":7,"title":["Suntanning with sunscreens: a comparison with sunbed tanning"],"prefix":"10.1111","volume":"31","author":[{"given":"Brian L.","family":"Diffey","sequence":"first","affiliation":[{"name":"Dermatological Sciences Institute of Cellular Medicine University of Newcastle Newcastle UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2988-3428","authenticated-orcid":false,"given":"Uli","family":"Osterwalder","sequence":"additional","affiliation":[{"name":"BASF PCN GmbH Monheim Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernd","family":"Herzog","sequence":"additional","affiliation":[{"name":"BASF Grenzach GmbH Grenzach\u2010Wyhlen Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,7,23]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.e4757"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.e5909"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4615-2626-1_4"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2133.2010.10165.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751-1097.2007.00271.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/phpp.12048"},{"key":"e_1_2_6_8_1","unstructured":"CIE.Standard Erythema reference action spectrum and standard erythema dose.
