Internet acne education with automated counseling tested in clinical trial
An Internet-based acne education program that included automated counseling was not better than a standard educational website in improving acne severity and quality of life in adolescents, according to an article published online by JAMA Dermatology. Acne vulgaris is a chronic inflammatory skin disease that is prevalent among adolescents. Patient education is an important part of managing acne along with medication. However, the effect of patient education on clinical outcomes is not well characterized in dermatology publications. Researcher April W. Armstrong, M.D., M.P.H., of the University of Colorado, Aurora, and her coauthors developed an educational website on acne that incorporated automated online counseling to simulate face-to-face encounters. A standard educational website on acne was also developed for comparison. Both websites included suggestions on preventing acne, as well as information on medications and an anti-acne skin care routine. The authors suggest their results may be explained by lower-than expected use of the study websites. They note that “despite a lack of differential effect between websites, our results indicate that the automated-counseling website improved short-term skin care behaviors” .“Therefore, interactive Internet-based education may still carry the potential to improve long-term clinical factors, such as acne severity and quality of life. This conclusion is significant given the importance of discovering modern and novel techniques to deliver patient education in dermatology,” the study concludes.
Sunburn: causes, treatments and prevention tips
Sunburn is the term for red, sometimes swollen and painful skin. It is caused by overexposure to ultraviolet (UV) rays from the sun. Sunburn can vary from mild to severe. The extent depends on skin type and amount of exposure to the sun. Sunburn is a serious risk factor for skin cancer and for sun damage. Because of variations in the intensity of UV radiation passing through the atmosphere, the risk of sunburn increases with proximity to the tropic latitudes. The higher the latitude, the lower the intensity of the UV rays. On a minute-by-minute basis, the amount of UV radiation is dependent on the angle of the sun. This is easily determined by the height ratio of any object to the size of its shadow. The greatest risk is at solar noon, when shadows are at their minimum and the sun's radiation passes more directly through the atmosphere. Regardless of one's latitude (assuming no other variables), equal shadow lengths mean equal amounts of UV radiation. The symptoms of sunburn vary from person to person. You may not notice redness of the skin for several hours after the burn has begun. Peak redness will take 12-24 hours. Minor sunburns typically cause nothing more than slight redness and tenderness to the affected areas. In more serious cases, blistering can occur. Extreme sunburns can be painful to the point of debilitation and may require hospital care. Commercial preparations are available that block UV light, known as sunscreens or sunblocks. They have a sunburn protection factor (SPF) rating, based on the sunblock's ability to suppress sunburn. Basically, the higher the SPF rating, the lower the amount of direct DNA damage. A sunscreen rated as SPF 10 blocks 90% of the sunburn-causing UVB radiation; an SPF20 rated sunscreen blocks 95%. Modern sunscreens contain filters for UVA radiation as well as UVB. Although UVA radiation does not cause sunburn, it does contribute to skin aging and an increased risk of skin cancer. Many sunscreens provide broad-spectrum protection, meaning that they protect against both UVA and UVB radiation. Research has shown that the best protection is achieved by application 15 to 30 minutes before exposure, followed by one reapplication 15 to 30 minutes after exposure begins. Further reapplication is only necessary after activities such as swimming, sweating, and rubbing.
Research links psoriasis, depression
Psoriasis is a common skin condition that affects millions of Americans and it doesn’t just affect their skin. This disease can have a significant impact on quality of life. New research, presented at the American Academy of Dermatology’s 2015 Summer Academy Meeting in New York, indicates that psoriasis patients may have an increased risk of depression. Psoriasis is a chronic inflammatory disease that typically involves the skin and joints. The majority of people diagnosed with the condition have plaque psoriasis, characterized by red, raised patches of skin covered with silvery-white scales. Using data from the National Health and Nutrition Examination Survey, Dr. Ho and his colleagues studied cases of psoriasis and depression in a pool of 12,382 adult patients. About 16.5 percent of the psoriasis patients studied met the criteria for major depression, and the odds of having major depression were doubled among psoriasis patients. The association between the two conditions remained significant even when researchers adjusted for other risk factors, including age, gender, race, body mass index, physical activity, history of alcohol use and smoking, and history of other conditions like myocardial infarction, stroke and diabetes mellitus. Dr. Ho believes the connection between psoriasis and depression may be linked to the public’s stigmatization of psoriasis. The condition is highly visible on the skin, especially in the summer months when more skin is exposed, he says, and those who are unfamiliar with the disease may react unfavorably to people who have it. “The public should know that psoriasis is not contagious, so there is no need to act differently around psoriasis patients than you would around anyone else,” Dr. Ho says. Dr. Ho initially expected that patients’ likelihood of depression would be linked to the severity of their psoriasis, but his research indicated that this is not the case. “It seems that it really depends on the patients’ view of themselves, rather than the extent of their psoriasis,” he says. “Psoriasis has far-reaching implications for patients’ physical and mental health, and that can include an increased risk of depression,” Dr. Ho says. “I encourage all psoriasis patients to see a board-certified dermatologist for treatment, which may help improve their quality of life”.
"Hidden" fragrance compound can cause contact allergy
Linalyl acetate, a fragrance chemical that is one of the main constituents of the essential oil of lavender, is not on the list of allergenic compounds pursuant to the EU Cosmetics Directive. Thus, it does not need to be declared on cosmetic products sold within the EU. Recent studies at the University of Gothenburg have shown that linalyl acetate can cause allergic eczema. In accordance with the EU Cosmetics Directive, makeup, ointments, shampoo, deodorants, toothpaste and other products must contain a declaration of ingredients in order for consumers to avoid the substances to which they are allergic. Cause of contact allergy Linalyl acetate, a fragrance chemical, is an exception -- it is not listed in the directive and does not have to appear in declarations of ingredients. The substance is mildly allergenic. New studies at Sahlgrenska Academy have found that it can react with oxygen in the air to form strongly allergenic hydroperoxides. Thus, linalyl acetate may be a common cause of contact allergy. Allergic reactions: the study included 1,717 subjects who were being assessed for eczema related to contact allergy. Approximately 2 percent of them had allergic reactions to oxidized linalyl acetate'. That may seem like a small percentage,' says Lina Hagvall, a researcher at the University of Gothenburg. 'But it is approximately the same result as for the fragrance compounds listed in the Cosmetics Directive”. Broad range of tests: the subjects who reacted to oxidized linalyl acetate were also exposed to other fragrance compounds that are part of routine testing these days. A total of 57 percent of them had no allergic reaction”. The trials suggest that a broad range of tests is required to detect contact allergies to fragrance compounds,' Dr. Hagvall says. 'Current tests do not identify the majority of people who have contact allergy to oxidized linalyl acetate”. Hard to avoid: because the substance is not declared on cosmetic products, consumers have trouble avoiding it, which can turn allergic eczema into a more severe, long-term condition. According to the researchers, the study findings should lead to inclusion of oxidized linalyl acetate among the fragrance compounds used for diagnosis of contact allergy. The substance should also appear in the declaration of ingredients for cosmetic products.
Researchers identify drug candidate for skin, hair regeneration among scarred victims of burns and trauma
Johns Hopkins researchers have identified a novel cell signaling pathway in mice through which mammals — presumably including people — can regenerate hair follicles and skin while healing from wounds. The discovery, summarized in an article published Aug. 6 in the journal Cell Stem Cell, could, they say, eventually help spur the growth of new hair, skin or other organ tissue in scarred victims of burns and other injuries. Our study “uncovers a novel role for a protein that works as a master regulator of regeneration in the skin,” says senior study author Luis A. Garza, M.D., Ph.D., associate professor of dermatology at the Johns Hopkins University School of Medicine. “Medications that turn on this protein have the powerful potential to decrease scarring as healing of wounds takes place, thereby promoting skin and hair follicle regeneration”. Garza says his team’s work is based on the knowledge that damaged skin releases double-stranded RNA (dsRNA) — genetic information normally carried by some viruses — that is sensed by a protein called toll-like receptor 3 (TLR3). TLR3, which in other contexts plays a fundamental role in recognizing some disease-causing organisms and activating the immune system, during wounding also activates the genes IL6 and STAT3 to promote hair follicle regeneration. TLR3 also activates other molecules involved in hair development, including the Wnt and Shh signaling pathways and a gene called EDAR, which makes the protein ectodysplasin and plays an important role in skin development. “A lot of human disability is from scarring,” Garza says. “After a heart attack, we’re really good at replacing the blood flow, but it’s the scar on the heart afterward that’s the real problem. We and others in the field of regenerative medicine are interested in how to enhance or trigger regeneration in such situations”. For the study, Garza and colleagues compared the protein expression of certain genes in healed wounds in two groups of mice. One group was genetically proficient in wound-induced hair neogenesis, a process in mice and rabbits in which skin and hair follicles regenerate after wounds. The other inbred group of mice was noted to lack this ability. Expression of TLR3 was three times higher in the mice that were better able to regenerate hair. The clinical translation of this work is promising because work has already started, says Garza. Drug companies are already developing products to activate TLR3 to trigger the immune system, and these same products could be tested to promote regeneration. But Garza cautions that clinical applications of the team’s discoveries must await many more experiments and the development and testing of drugs that target the pathway they uncovered. He also made clear that the information might not be as applicable to conditions unrelated to scarring or to those whose hair follicles are lost from male pattern baldness.
Millions of plastic particles found in cosmetic products
Everyday cosmetic and cleaning products contain huge quantities of plastic particles, which are released to the environment and could be harmful to marine life, according to a new study. Research at Plymouth University has shown almost 100,000 tiny ‘microbeads’ – each a fraction of a millimetre in diameter – could be released in every single application of certain products, such as facial scrubs. The particles are incorporated as bulking agents and abrasives, and because of their small size it is expected many will not be intercepted by conventional sewage treatment, and are so released into rivers and oceans. Researchers, writing in Marine Pollution Bulletin, estimate this could result in up to 80 tonnes of unnecessary microplastic waste entering the sea every year from use of these cosmetics in the UK alone. The latest study was led by PhD student Imogen Napper, together with Professor of Marine Biology Richard Thompson, Professor of Organic Geochemistry Steve Rowland and Postdoctoral Researcher of Analytical Chemistry, Dr Adil Bakir Imogen said: “As the study unfolded I was really shocked to see the quantity of microplastics apparent in these everyday cosmetics. Currently, there are reported to be 80 facial scrubs in the UK market which contain plastic material, however some companies have indicated they will voluntarily phase them out from their products. In the meantime, there is very little the consumer can do to prevent this source of pollution”. Subsequent analysis using electron microscopy showed that each 150ml of the products could contain between 137,000 and 2.8million microparticles. Professor Richard Thompson, who has been studying the effects of litter in the marine environment for over 20 years, said: “Using these products leads to unnecessary contamination of the oceans with millions of microplastic particles. There is considerable concern about the accumulation of microplastics in the environment; our previous work has shown microplastics can be ingested by fish and shellfish and there is evidence from laboratory studies of adverse effects on marine organisms”.

COUNTERFEIT COSMETICS PRODUCTS
Every year the cosmetics industry suffers from multi-billion dollar losses due to counterfeit cosmetics products. This lost revenue may have a negative impact on market share, and can result in a further erosion of sales. If the counterfeit products cause health problems in consumers, this can damage the reputation and brand image for the manufacturers of the authentic cosmetics. Early and rapid detection of counterfeit products is one way to address counterfeiting in both domestic and export markets. Highlighted in this work is a multivariate analysis technique for sample comparison using statistical analysis tools for easy comparison between complex samples. The described LC-MS and informatics workflow as implemented with the UNIFI Scientific Information System using high-resolution mass spectrometry can be adopted for cosmetics, food and beverage, and pharmaceutical sample analysis.

SOLVAY AND L’ORÉAL TEAM UP TO PROMOTE SUSTAINABLE PRACTICES AMONG GUAR BEAN FARMERS IN INDIA
Solvay and L’Oréal have teamed up in a scalable three-year project to teach and promote sustainable agricultural practices among 1,500 guar bean farmers across ten villages in India’s desert region of Bikaner, Rajasthan state. Solvay is a world leader in guar derivatives and supplies its customers who formulate these ingredients in a variety of applications such as in food, cosmetics, oil & gas extraction and textile industries. Grown mainly in India’s semi-arid regions, guar is the main resource for many farming communities but its production is volatile as it relies on monsoon rains. Solvay’s “Sustainable Guar Initiative” aims to empower countless farmers with the tools and knowledge to cultivate the crop through good agricultural practices, resulting in more continuous, high-yield production. Solvay’s Novecare Global Business Unit (GBU) in 2013 launched the initiative, which is also implemented by non-governmental organization TechnoServe, as part of the Group’s sustainable development strategy Solvay Way. “Solvay’s initiative and partnership with L’Oréal, acting as a founding member, brings many benefits –for farmer communities, their environment as well as for demanding industrial applications. The project will help farmers improve the use of water and preserve the soil, it will raise their income and support local communities” said Emmanuel Butstraen, President of Solvay Novecare and sponsor of the “Sustainable Guar Initiative”. “Our approach will also reinforce the availability of bio-based guar for industries and allow them to promote their ambitious sustainability goals”. “Our partnership with Solvay is a concrete implementation of our “Sharing Beauty with All” sustainability commitment. By improving yields while promoting a suitable model of sustainable agriculture, we will improve the livelihood of farmers and protect local resources such as water, soil and biodiversity. This program will allow ensuring a durability of income for guar bean farmers while considering the impact of climate change into their activities” said Laurent Gilbert, Director for International Development of Advanced Research at L’Oréal.
