    Tanorexia, when a shade more is never enough

    30 Nov Tanorexia, when a shade more is never enough




    Science Daily

    Patricia Krentcil became sadly famous a few months ago for taking her 5-year-old daughter to a tanning salon. The little girl suffered skin burns and the authorities intervened in the case, which gained major media coverage and even led to a ban in New York on minors entering tanning salons.


    Krentcil, aged 44, suffers from tanorexia, a new cosmetic addiction that describes people obsessed with achieving a darker skin tone. In 2005, a study by the University of Texas (USA) showed that this disease existed and pointed out that the production of endorphins (chemical substances produced by the brain that cause a feeling of euphoria) triggered by tanning could be addictive.

    Super Protector: child app for the sun

    28 Nov Super Protector: child app for the sun



    Google Play

    It is not always easy to get children to understand and obey parents’ instructions. And it is harder still to stop them from exposing their skin to the sun. They are having fun and mum and dad tips are very, very boring.... A new learn-by-playing smartphone app helps children protect themselves from UV light.


    The Spanish Cancer Association has launched this app for Android handsets so that children can interiorize the importance of avoiding over-exposure to the sun and so avoid future negative consequences for their health. Advice and play are combined in a game, so putting on sunscreen, wearing a hat, drinking water and playing in the shade all increase their score. The app is free and can be downloaded from the Google Play store.

    Cosmetics & Toiletries

    We are spending more and more on taking care of our personal appearance and the health of our skin. The market in the United States saw growth of 4.2% in 2011 and reached a volume of US $38 billion. Nail polish, facial treatments, products for men and luxury perfumes saw a particular increase in sales.


    The latest report by Kline & Company, which performs an annual follow-up of the industry in the United States, notes that the increase in sales of skin-care products was due to the tremendous growth in the range of available products for men, who are showing increasing concern for their appearance. The consumption of luxury perfumes also increased (10%), with Hispanic and Afro-American customers showing a preference for these products. But the record goes to nail polish, which showed a spectacular increase of 30% in sales, due to the new trends in colours and special effects of varnishes.

    Everything About Retinol

    25 Nov Everything About Retinol



    Mayo Clinic

    University of Maryland

    Retinol (vitamin A) is one of the most common ingredients in anti-ageing cosmetic creams, lotions and oils. Although the most effective results are achieved by applying retinol to the skin, it is also supplied in the form of vitamin supplements. Is it as effective as they say? What don’t we know about this component?


    In theory, it’s all benefits: retinol helps against wrinkles and premature signs of ageing, sun or age spots (photoageing), acne and pigmentation problems, and also improves the texture of the skin. Its antioxidant capability fights free radicals in our body and protects against cell damage. It also stimulates the production of collagen and elastin, which give the skin strength and flexibility.
