“…Reported data had to provide or to allow the calculation of time spent in the sun during parts of day or during days during which there was effective sun exposure, with knowledge of sunscreen use before or during effective sun exposure. Relevant information of methods or on results were sometimes found in the Discussion section of articles, e.g., time spent in the sun in 1 Danish study, 7 or the notion that during a randomized trial in France, an investigator was permanently present in holiday villages and had daily contacts with trial participants. 8 …”

“…One study found that UV doses received were considerably higher when sunscreens were used. 7 Four studies recorded sunburns and found higher proportions of subjects with sunburn when a sunscreen was used, especially when the SPF was high. According to reports, differences in sun sensitivity between sunscreen users and nonusers were not likely reasons for explaining results on durations and on sunburns, although these results were never statistically adjusted on sun sensitivity of study participants.…”

Sunscreen use is often proposed for sun protection because of their ability to block UV-induced sunburns (the sun protection factor -SPF). 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 (i.e., intentional sun exposure), sunscreen use was associated with duration of sun exposure 13-39% 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-blind randomized trials conducted among young sun seekers found daily sun exposure duration, especially sunbathing, 19-25% longer with use of SPF 30 than with use of SPF 10 sunscreens. One randomized trial in a holiday resort in France found a 3-13% increase in sun exposure duration with use of SPF 12 versus SPF 40 sunscreen. But, the SPF 12 groups used 3.6-4.2 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. ' 2007 Wiley-Liss, Inc.

“…32 Fatores tipicamente associados a queimaduras solares inesperadas são a aplicação escassa de protetor, uso de formulações excessivamente líquidas, má distribuição de spray e falha na reaplicação após o banho. 33 O uso de protetor solar é recomendável, mas sempre em combinação com outras medidas de proteção como a sombra, chapéu, óculos de sol e roupa (cobrindo o decote, os antebraços e com tecido apropriado). 34 No que concerne ao exame objectivo, em Portugal o exame cutâneo completo foi efectuado em 96% dos casos (contrastando com 72% da média europeia que variou entre 32,3% na Suíça e 100% em Espanha 20 ), valor que foi constante ao longo dos anos e traduz uma abordagem metódica da dermatologia portuguesa.…”

RESUMO -Introdução:A incidência dos cancros da pele tem vindo a aumentar nos últimos anos em todo o mundo. O alerta das populações para a prevenção primária, promovendo o conhecimento sobre factores de risco e incentivando melhores comportamentos de proteção solar, bem como a prevenção secundária fomentando o auto-exame de pele e rastreios, são estratégias fundamentais da luta contra o cancro da pele. A Sociedade Portuguesa de Dermatologia e Venereologia e a Associação Portuguesa de Cancro Cutâneo, têm colaborado com o Euromelanoma, uma iniciativa pan-Europeia de informação e rastreio de cancro da pele, desde o ano 2000. Material e Métodos: Este estudo transversal consistiu na avaliação dos dados do formulário do Euromelanoma preenchido aquando do rastreio no dia do Euromelanoma, em Portugal Continental e Ilhas, nas instituições públicas e privadas, de 2010 a 2016. Resultados: Foram incluídos 9862 indivíduos, 63% mulheres e 37% homens, com uma média de idades de 48 anos. O número de lesões clinicamente suspeitas de malignidade, ou de risco de malignidade, foi relativamente baixo mas consistente com outros estudos publicados do Euromelanoma: 3% carcinoma basocelular, 0,4% carcinoma espinocelular, 1% melanoma e 6% de queratoses actínicas. Conclusão: A iniciativa do Euromelanoma suscitou a nível nacional e internacional uma maior sensibilização das populações para a temática do cancro da pele, com amplificação das mensagens pela comunicação social, assumindo-se como um importante tema de saúde pública, reconhecido pelas autoridades políticas e sanitárias.

“…The COLIPA guidelines, which served as the basis for the tests presented here, are not intended to reflect the reality of a day at the beach or in the mountains. In fact, in reality even further factors have to be considered, such as not applying enough of the sunscreen [21][22][23] , which undoubtedly further impair sun protection [24] .…”

The present in vivo investigation using a total of 30 healthy adult volunteers with Fitzpatrick skin type II examines the persistent efficacy of sunscreens using liposomal suspensions as the vehicle. Based on the COLIPA guidelines, the protective effect of a single application of 4 different liposomal sunscreen formulations (sun protection factors, SPFs: 50+, 30, 25 and 15) against sunburn at the recommended amount of 2 mg/cm² was determined after exposure of the skin to plain water and salt water and after profuse perspiration. Under the influence of plain water, salt water and sweating, the SPF values of sunscreen 1 (labeled SPF of 50+) were reduced only marginally to 97, 96 and 99%, respectively, those of sunscreen 2 (labeled SPF of 30) to 97, 96 and 99%, respectively, those of sunscreen 3 (labeled SPF of 25) to 90, 83 and 91%, respectively, and those of sunscreen 4 (labeled SPF of 15) to 96, 96 and 95%, respectively. This set of data shows that despite plain water and salt water immersion or profuse sweating, the liposomal sunscreen formulation may deliver a long-lasting protective effect in everyday situations encountered by outdoor workers or during leisure activities.
