    Sun protection without creams

    Sunscreens are not the only way to protect the skin from ultraviolet rays. It so happens, anyway, that around 40% of people who use sunscreens get burned because they fail to apply the product properly. There are other ways of protecting the skin that can be combined with sunscreens.


    To ensure full protection for our skin it is advisable to use five strategies – separately or, better yet, in combination. 1. Wear sunglasses to prevent premature cataracts and ocular melanoma. 2. Make good use of beach umbrellas (a mere 14% of children on beaches are actually protected by them). 3. Seek out trees, because these afford natural protection from the sun (SPF of 10 or more). 4. Wear loose clothing to cover up the skin. 5. Avoid sunbathing between 3 pm and 5 pm in summer when the sun’s radiation is strongest.

    Fake tanning: bronzed skin, no cancer risk

    28 Mar Fake tanning: bronzed skin, no cancer risk




    Mayo Clinic

    Fake tanning products are the perfect solution for people who like to have a bronzed skin all year round, yet want to reduce the negative effects of solar radiation and prevent skin cancer. Here we consider the advantages and disadvantages.


    Current sunless tanning products have come a long way since the first such products were launched on the market in the 1960s. Such products were not entirely successful, however, due to the uneven and orangeish tan they produced. Current tanning products not only give a more natural, long-lasting colour, they cater for all tastes and skin types. They come in different forms (cream, gel, spray, wipe, etc) and often offer additional benefits (as moisturizers, sunscreens, anti-wrinkle products, etc). Read More

    Animal testing for cosmetics banned in Europe

    25 Mar Animal testing for cosmetics banned in Europe



    BBC News

    The ban on the sale of animal-tested cosmetic products came into force in the 27 countries of the EU this March. The European Commission, committed as it is to supporting alternative methods for testing the toxicity and efficacy of cosmetic ingredients, is now trying to persuade other countries to adopt the European standards.


    Although a petition to stop live animal testing, signed by four million people, was presented to the European Commission as far back as 1996, this recent decision is a direct result of a process that the EU launched in 2003 that allowed a period of 10 years for adaptation to the ban. European associations against animal abuse have celebrated the news as a major victory in defence of the dignity of animals. Read More

    Fascinating alum crystal

    Alum crystal, used by ancient civilizations, has come back into fashion with the rise of natural cosmetics. It has many properties, including as a body deodorant. How does it benefit the skin? Is the aluminium it contains hazardous?


    Alum crystal is a naturally occurring sweet-tasting mineral that looks like translucent glass. It is usually composed of an aluminium sulfate and a sulfate from another metal. The most commercially exploited alum is the hydrated form of potassium aluminium sulfate (potassium alum), which comes from a volcanic igneous rock called aluminiferous trachyte; it can also be manufactured industrially, however.
