    Our interconnected, networked reality occasionally allows urban legends and misconceptions to proliferate rapidly. Also with regard to care of our skin. The latest myth says that sleeping position has an impact on the appearance of wrinkles on the face. True or false?

     

    It seems logical: if you sleep on your side and place your face against the pillow, your skin will seem to wrinkle. And especially so if you sleep face down ... Hasty conclusion: over the years these sleeping positions lead to wrinkles and enhance facial ageing by causing sagging. So, best sleep on your back, and maybe even use a U-shaped pillow to stop rolling over during the night. It has also been recommended to use satin instead of cotton pillowcases, to allow the face to slide more easily. Then a mass-circulation medium – e.g., The Huffington Post – discusses the issue and launches a chain of half-truths repeated ad nauseam in websites, print media and TV channels. Thus is the false myth created. Read More

    Sunscreens: What’s new under the sun?

    21 Aug Sunscreens: What's new under the sun?

    Sunscreens are not what they used to be. In the 1970s and 1980s, what mattered was a deep tan and UV radiation protection barely received a mention. But devastating skin cancer figures forced a rule change in a market worth about 1,000 million dollars in the USA alone and which relies on innovation to diversify.

     

    Correctly labelling a sunscreen is no trivial task. The US Food and Drug Administration (FDA) has taken more than 30 years to bring order to the sunscreen market and set standards to test the effectiveness of products. From 18 June 2012, sunscreens sold in the USA have to comply with new rules established by the FDA. They are required to be "broad spectrum”, i.e., they must protect against both UVA (responsible for premature ageing) and UVB (responsible for sunburn) and they must indicate how many minutes they remain effective after immersion in water.

    Cosmetotextiles: wearable skincare

    30 Jul Cosmetotextiles: wearable skincare

    They arrived with the turn of the century and the development of microencapsulation. With their promise of slimming and firming the body, they began to timidly adhere to the fibres of tights, leggings and even lingerie. They are already to be found in skinny jeans, shorts and T-shirts. For both women and men. Cosmetotextiles, in combining the alchemy of cosmetics with the appeal of certain textiles, are revolutionizing skin care.

     

    Cosmetotextiles are cosmetics that are worn. According to Textiles Intelligence, the cosmetotextile market is a promising one, worth 500 million euros in 2013. It is based on an innovative idea: to use the clothes we wear daily next to the skin to remove excess fat, boost skin hydration and firmness and improve muscle tone. How? By introducing, in the fibres of clothing, microparticles of certain ingredients – like caffeine (a microcirculation activator), Aloe vera (a moisturizer), retinol (a regenerator) and vitamin E (an anti-oxidant) – so that, with our movements, these substances can be released into the epidermis.

    Sunscreen against wrinkles

    15 Jul Sunscreen against wrinkles

    Annals of Internal Medicine

    Summer is here and many people are planning to buy the traditional sunscreen to take to the beach. We all know that this is how to protect our skin from photoageing and how to minimize the risk of serious related disorders. A new Australian study confirms that people who use sunscreen have fewer wrinkles.

     

    Some people – although not many – use a sunscreen (or a cosmetic containing sunscreen) daily on parts of the body exposed to the negative effects of sunlight on the skin. Others do not use sunscreen, or only do so occasionally. A group of researchers has finally confirmed what dermatologists have long known: the sun causes wrinkles and dry skin. The study, which included 900 volunteers aged between 25 and 55, was conducted over four and a half years in Australia, a country with a mainly white population that receives a great deal of sunshine.
