Abstract
Background Sunscreens are one of the most widely used products among cosmetics and personal care products. Recent studies have shown that some of sunscreen formulations may contain toxic, carcinogenic, or even nonallowed chemicals that may affect skin, cells, and hormones. Materials and methods This study aimed to develop and validate a method that allows the determination of sunscreen ingredients by gas chromatography-mass spectrometry (GC-MS). Analysis of original sunscreen products (n=5) from a licensed pharmacy and counterfeit sunscreen products (n=5) from local markets in Jordan was performed using GC-MS. pH stability of the sunscreen samples were also monitored under different storage temperatures. Topical application of sunscreens on mice skin was conducted to study their effects on liver and kidney enzymes' function. Results In terms of pH stability, there is a significant change in pH at different degrees of temperature between the products. Diethyl phthalate (DEP) was detected in two counterfeit products and was not mentioned on the ingredients' label. DEP was reported for its percutaneous absorption and systemic uptake in the literature. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were significantly increased with a P<0.005 in some groups treated with original sunscreens under sun radiation. Creatinine showed a significant decrease in some groups treated with original and counterfeit sunscreens, while blood urea nitrogen (BUN) showed no differences. Conclusion This study presents a method that allows the scanning and profiling of sunscreen ingredients as well as investigates their stability, permeation, and toxicity. Profiling of sunscreen product, changing in pH stability, and analyzing kidney and liver enzymes' level would be of a great impact on products' safety and consumers' health.

Brazilian consensus on photoprotection. An Bras Dermatol 2015; 89:1-74.

Abstract
Brazil is a country of continental dimensions with a large heterogeneity of climates
and massive mixing of the population. Almost the entire national territory is located
between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the
south certainly makes Brazil one of the countries of the world with greater extent of
land in proximity to the sun. The Brazilian coastline, where most of its population
lives, is more than 8,500 km long. Due to geographic characteristics and cultural
trends, Brazilians are among the peoples with the highest annual exposure to the sun.
Epidemiological data show a continuing increase in the incidence of non-melanoma and
melanoma skin cancers. Photoprotection can be understood as a set of measures aimed
at reducing sun exposure and at preventing the development of acute and chronic
actinic damage. Due to the peculiarities of Brazilian territory and culture, it would
not be advisable to replicate the concepts of photoprotection from other developed
countries, places with completely different climates and populations. Thus the
Brazilian Society of Dermatology has developed the Brazilian Consensus on
Photoprotection, the first official document on photoprotection developed in Brazil
for Brazilians, with recommendations on matters involving photoprotection.

Abstract
This study analyzed the content of sun-care product advertisements in five major U.S. parenting magazines with high circulation: Family Circle, Parents, Family Fun, Parenting (Early Years), and Parenting (School Years). The study examined what information sun-care product advertisements tell parents about skin cancer prevention and about sunscreen use for themselves or for their children based on the Health Belief Model concepts of perceived benefits and perceived barriers. Results showed that the most commonly mentioned benefit of the product was that it blocks ultraviolet A (UVA) and ultraviolet B (UVB) rays. One-third of the ads promoted the product's effectiveness in overcoming four of the barriers that prevent people from using sunscreens: eye irritation, skin irritation, an unpleasant smell, and the need to reapply sunscreen too often or after physical activity. However, only a few of the ads provided information about the consequences of unprotected sun exposure or mentioned methods of sun protection or skin cancer prevention other than sunscreen use. We discuss the implications of these messages for parents' ability to understand correctly how to protect their children from damaging sun exposure.

Abstract
The use of sunscreens with sun protective cloths is the photoprotection way mostly used by Occidentals. During sweating or a bath, those products should be still efficient. As the emulsion is the mostly used type of product format, it is essential that the scientist knows how to formulate an emulsion which will be water resistant. The HLB (hydrophilic-lipophilic balance) of a formulation has high influence on this characteristic.
