    Some sunbathers take off their sunglasses to avoid marks. Others simply forget them. But sunglasses are absolutely necessary to prevent eye damage, most especially in periods of lengthy exposure to UV rays, whether in summer or winter, in the mountains or by the sea.

     

    The eyes are protected from the sun by their own internal configuration and by the eyelashes and eyelids. But in extreme conditions the eyes are as vulnerable as the skin to the effects of UV rays. Studies confirm that prolonged unprotected exposure of the eyes to the sun can have dire consequences and cause various disorders ranging from simple conjunctivitis and premature cataracts to conjunctival cancer and pterygium (excessive conjunctival growth that blurs vision).

    Why do I have open pores?

    20 Oct Why do I have open pores?

    Everyone has open pores, but they are more noticeable in some skins than in others. The blame may lie with genetics, as is often the case, but only partly. Temperature and relative humidity, exposure to the sun, skin type, hormonal changes and age also enlarge the pores and make the skin look rough. The question is, however, what’s the solution?

     

    We have about two million pores, which are absolutely necessary for the proper functioning of the skin, as they eliminate toxins, regulate temperature and hydrate the skin. But it's hard to appreciate all this when you can’t help but see them – because they are dilated or dirty from an accumulation of dead cells and other impurities, making your skin look unhealthy and aged. And this is not necessarily for lack of care. Read More

    Sunscreens are not enough to avoid cancer

    15 Oct Sunscreens are not enough to avoid cancer

    A few years ago the European Union banned use of the term total block" in sunscreen labels because it led to confusion. There is, in fact, no photoprotection that is 100% effective against UV radiation. A study published recently in Nature confirms that sunscreens do not protect fully against melanoma but this does not mean we should stop using them.

     

    The research – conducted by scientists from the Institute of Cancer Research in London and Cancer Research UK Manchester Institute – demonstrates that even a sun protection factor (SPF) of 50 allows some DNA-damaging radiation to penetrate the skin, possibly causing melanoma. This, the most aggressive form of skin cancer, affects every year about 160,000 people worldwide, according to WHO, with the number of cases in Spain increasing by 38% in the last four years.

    The skin and the impact of pollution

    It’s something like the layer of dust and dirt that accumulates on cars between washes. Even despite make-up and daily care, pollution particles stick to our skin, dehydrate it, make it less firm and radiant and even cause blemishes. Air pollution is as harmful as smoking for the complexion. But depending on where we live it may be impossible to avoid it. What can we do to protect our skin?

     

    According to a report published by the European Environment Agency (EEA) in 2013, the air we breathe in Europe is far from clean. In fact, the EEA says that over 90% of the inhabitants of European cities are exposed to worrying levels of PM2.5 (particles smaller than 2.5 microns) – largely originating in diesel-vehicle emissions – and excessively high ozone levels.
