Among suntan seekers, however, risk of cutaneous melanoma may be increased because of extended sun exposure duration. We made a systematic review of the evidence linking sunscreen use to sun exposure duration. Five observational studies found that when sun exposure was associated with willingness to get a tan or to stay longer in the sun (<jats:italic>i.e.<\/jats:italic>, intentional sun exposure), sunscreen use was associated with duration of sun exposure 13\u201339% longer. Paradoxically, sunburns tend to be more frequent among sunscreen users, probably because of greater natural sun sensitivity. When sun exposure was not intentional, sunscreen use did not increase time spent in the sun. Two European double\u2010blind randomized trials conducted among young sun seekers found daily sun exposure duration, especially sunbathing, 19\u201325% longer with use of SPF 30 than with use of SPF 10 sunscreens. One randomized trial in a holiday resort in France found a 3\u201313% increase in sun exposure duration with use of SPF 12 versus SPF 40 sunscreen. But, the SPF 12 groups used 3.6\u20134.2 more sunscreen than the SPF 40 group, and thus the actual SPF in the SPF 12 group was higher than in the SPF 40 groups. In conclusion, sunscreen use leads to longer duration of sun exposure when sun exposure is intentional, but not when sun exposure is non intentional. \u00a9 2007 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ijc.22745","type":"journal-article","created":{"date-parts":[[2007,4,5]],"date-time":"2007-04-05T14:52:25Z","timestamp":1175784745000},"page":"1-5","source":"Crossref","is-referenced-by-count":168,"title":["Sunscreen use and increased duration of intentional sun exposure: Still a burning issue"],"prefix":"10.1002","volume":"121","author":[{"given":"Philippe","family":"Autier","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathieu","family":"Boniol","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean\u2010Fran\u00e7ois","family":"Dor\u00e9","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,4,5]]},"reference":[{"key":"e_1_2_6_2_2","series-title":"IARC handbooks of cancer prevention","volume-title":"sunscreens","author":"International Agency for Research on Cancer","year":"2001"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0215(20001201)88:5<838::AID-IJC25>3.0.CO;2-X"},{"key":"e_1_2_6_4_2","first-page":"403","article-title":"Relationship of cutaneous malignant melanoma to individual sunlight\u2010exposure habits","volume":"76","author":"Holman CD","year":"1986","journal-title":"J Natl Cancer Inst"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/jnci\/90.24.1873"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.0022-202X.2004.23548.x"},{"key":"e_1_2_6_7_2","series-title":"IARC monographs on the evaluation of carcinogenic risks to humans","volume-title":"solar and ultraviolet radiation","author":"International Agency for Research on Cancer.","year":"1992"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.141.8.967"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.141.8.950"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0091-7435(92)90029-H"},{"key":"e_1_2_6_11_2","first-page":"37","article-title":"Beach holiday sunburn: the sunscreen paradox and gender differences","volume":"64","author":"McCarthy EM","year":"1999","journal-title":"Cutis"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0781.1996.tb00193.x"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0781.1997.tb00215.x"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1037\/0278-6133.13.5.412"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1067\/mjd.2000.103984"},{"key":"e_1_2_6_16_2","unstructured":"Commission Internationale de l'Eclairage.CIE standard: erythema reference action spectrum and standard erythemal dose CIE S 007\/E\u20101998 CIE Vienna 1999."},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1093\/jnci\/91.15.1304"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1054\/bjoc.2000.1429"},{"key":"e_1_2_6_19_2","first-page":"RR","article-title":"Preventing skin cancer","volume":"52","author":"USPSTF (US Preventive Services Task Force).","year":"2003","journal-title":"Morb Mortal Wkly Rep"},{"key":"e_1_2_6_20_2","unstructured":"NCI (National Cancer Institute).Skin cancer (PDQ\u00ae): prevention: melanoma.
