Predictive factors of sun protection behaviour among global airline pilots
Photodermatology, Photoimmunology & Photomedicine, 2022AbstractBackgroundAirline pilots face significant ultraviolet radiation exposure resulting in an increased risk of sun damage and skin cancers. We aimed to evaluate sun‐protective practices and associated factors among airline pilots.MethodsWe disseminated an online questionnaire evaluating the use of sunscreen, sunglasses, hats and protective clothing

In vitro approaches to evaluation of Sun Protection Factor
Toxicology in Vitro, 2007The efficacy of sunscreen products has been recognized as an important public health issue. Adequate methods for assessment of the level of protection should be developed and standardised. While the SPF COLIPA testing method in vivo has been used for years, preference should be given to in vitro testing methods as in vivo methods raise ethical concern.

Determination of sun protection factors in the hairless mouse
International Journal of Cosmetic Science, 1981SynopsisA laboratory method for determining sun protection factors (SPF) in the hairless mouse has been developed. The ability of the method to predict the SPF in man has been investigated using sunscreen ingredients and finished products with known activities in man. The results indicate that the hairless mouse can be used to assess sunscreen products

Durability of the sun protection factor provided by dihydroxyacetone
Photodermatology, Photoimmunology & Photomedicine, 2004Background/Purpose: The sunless tanning agent dihydroxyacetone (DHA) is known to protect against longwave ultraviolet radiation (UVA) and visible light. Recently, our laboratory has shown that DHA in addition offers a modest sun protection factor (SPF) in humans. We conducted this study in order to investigate the durability of the SPF provided by DHA.

Elastic liposomes containing benzophenone-3 for sun protection factor enhancement
Pharmaceutical Development and Technology, 2011This work was focused on the loading of benzophenone-3 in elastic liposomes composed of egg phosphatidylcholine and cholesterol, prepared by the Bangham method. Samples were characterized in terms of particle size, polydispersity index (PI), zeta potential, encapsulation efficiency and in vitro photoprotection properties.

Up Date on Sun Protection Factor
2012The sun protection factor (SPF) refers to the level of protection of a sunscreen against UV rays and is expressed, according to the COLIPA recommendation as a numerical value, and in terms of low, medium, high, and very high protection as well. For the determination of SPF exist methods in vivo (on volunteers) and in vitro (laboratory tests on ...

Choosing an expected sun protection factor value.
Journal of cosmetic science, 2015Sun protection factor, SPF, is a measure of the efficacy of a topical sunscreen product; the higher the SPF, the greater the blockage of ultraviolet-induced erythema. While there are several methods to determine SPF, the Food and Drug Administration (FDA) methods are unique.

Clothing reduces the sun protection factor of sunscreens.
The British journal of dermatology, 2010Individuals are recommended to wait for 20 min following sunscreen application before dressing. However, this is probably seldom done in daily life, and therefore we investigated how dressing earlier than 20 min after application affected the sun protection factor (SPF).To determine the SPF of a sunscreen applied at different amounts at 4, 8 and 20 min
