The snow, the waiting has finally arrived, and with it the desire to take a week or just a weekend of skiing and hiking in the snow. To disconnect from everyday life, oxygen, and, why not tan. The sun at high altitude, however, is stronger and potentially more harmful than it takes to the sea in summer. And the risk sunburn, but not only, is always around the corner. To address this winter sun safely we must never forget to protect the skin from sunlight and to take specific precautions.
We spoke with Dr. Roberta Lovreglio, dermatologist, head of Ambulatory Oncologico League of Dermatological Tumori in Bari
WHY THE SUN IN WINTER, A High, is a particularly insidious?
For several reasons. First Mountain ultraviolet rays penetrate more easily in epidermis because they are more powerful and abundant. The intensity of solar radiation increases with increasing altitude, while the atmospheric pressure is reduced, thereby diminishing its power filter. To make things worse then it puts the glare of snow, which should be reflected radiation strikes the skin, not only from above but also from the bottom up, a little ‘like a boat where you reflect on the UV water’s surface. The damage of the sun is then the sum of the wind and cold, making the skin more sensitive and reduces the normal barrier hydrolipidic favoring irritation or cracking which in turn increases the vulnerability to sunlight. The temperatures are particularly hard because they also have harmful effects “anesthetic” and alter the perception of heat on the skin, exposing even more dangerous to the risk of burns. So, never exposed to the sun without adequate protection.CONSEQUENCES OF INADEQUATE PROTECTION?
As well as the traditional burns, including erythematic, skin blemishes of various kinds, rhagades, worsening already existing spots. But even without burning, if there is a duty to protect the joint action of the trio sun-cold wind inevitably causes dehydration, which can lead to a disillusionment of the skin, facilitating the formation of wrinkles and accelerating photo aging.
FOR PROTECTION FROM SUN MOUNTAIN MAY USE THE SAME SOLAR that uses AT SEA?
Given that environmental conditions are different than summer, we want products with the ad hoc, such as to allow the skin to cope with the many environmental aggression that has brought. No a spray, gel, milk products and very fluid. Yes, instead, a cream with a good texture, sufficiently dense and fat, which also have moisturizing and soothing properties, as well as protection, to put away the skin from the cold and the disillusionment. As the sun beats, should be used always guards very high (minimum SPF 30-40) by choosing filters, chemical or physical, depending on skin type, if it is particularly fragile, the better a solar physicist with a filter, such as zinc oxide and titanium dioxide, for all other You can use a product containing a chemical filter, the more fluid and easy to apply. Until recently, the disability of the first filter was linked to the fact that they left alone ant aesthetic always a whitish skin. Today, however, there are no more excuses: the problem is resolved and there are colored filters on the market that make the cream like a foundation and making the most aesthetically pleasing. In children, who are particularly sensitive skin, would be better to focus on very opaque paste to protection. Furthermore, it must be said that while at sea, as they are tan, you can gradually switch to solar less protective; in the mountains we must always use high protection for the duration of the holiday.
SEA PRODUCTS TO BE DRAWN MORE TIMES throughout the day, WHY IS SUDA AND BATHROOMS ARE A RECOVERY. IN THE MOUNTAINS WHERE THE SITUATION is radically different, only one CAN APPLY?
No. Again, the protection should apply at least one quarter of an hour before exposure to the sun and then every 3-4 hours, to an extent to cover the entire face, eyelids and ears, including massaging well until full removals of the product, so as to enable it to fully play his moisturizer. Even in the coldest days, in fact, walking or skiing, you can perspire and perspiration can slide off the product. It is therefore important to renew the solar frequently, especially on the most sensitive nose, lips and forehead. Do not forget also the area of the eyes, which must be repaired so always good glasses anti-UV, but must also be protected from further creams with high protection. Furthermore, we must always protect your skin even when the weather is bad. The clouds, in fact, only filter out some of the ultraviolet rays and only a uniform and consistent coverage of the sky provides an effective reduction in solar radiation.
THE NEED FOR LIPS attention?
Definitely yes. Should be protected with products targeted because they are particularly sensitive. Are in fact deprived of the hydrolipidic film that covers the skin of the face and tend to wither with greater ease. In addition, the cold, the breath of water vapor that is deposited on the lips tends to freeze, further weakening. If the effect of annoying temperatures and stiff wind add that of UV rays, the results can be annoying cracks, but even more serious problems such as inflammation of the lips. To defend them, the exhaustive use lipstick and moisturizing sunscreens with high protection, or better yet, a full screen. And for extra nourishment, after a day in the open air, the optimum is to apply oil-based vitamin E, which has an effect on the restructuring mucosa.
A SPEECH IN THE DELL’HERPES is LABIALE. Who suffers WHEN IN THE MOUNTAINS, has a good chance of seeing RIAPPARIRE BOLLE annoying CAUSED BY VIRUSES. YOU MAY DEFEND IT?
Before exposure to the sun, the women who have this problem should take a preventive treatment with antiviral drugs specific follow the advice of his dermatologist (usually just 2 or 3 tablets a week before departure). Once on the snow, the lips are particularly well protected not only by sunlight, even from the cold. In the mountains, in fact, though few know it, is mainly thermal stress, rather than induced by ultraviolet light, to trigger the virus. That is why I mentioned Supercoprenti stick containing paste, made of zinc oxide. And if, despite all the precautions, the bubbles burst, however, let it run to repair the pads with anti-herpes. Goodbye to the sun.
SOME OTHER ACCORGIMENTO?
Strengthen the internal defenses of the body, preparing the skin 1-2 weeks before a vacation in the mountains taking supplements based on vitamin C, vitamin E and stimulating the production of melanin, then continuing for at least a month after the end of the holiday. These drugs, taken together, have a powerful antioxidant activity and help prevent damage of the sun’s rays, free radical and therefore photo aging. Also, remember that in the mountains the password together to protect, moisturize it. Before, during and after exposure to the sun. This means that one should not start in the snow without having applied a good cream superidratante day, but at the same time with a rich, thick texture, antic old. Moreover, the end of the day, it’s important to have good deposable, to give the skin nutrients that provide water and always maintain that the elastic.
So far we have talked about FOTOPROTEZIONE IN THE MOUNTAINS. BUT THE SKIN FROM SUN PROTECTION IS ALSO IN THE CITY, BEAUTIFUL DAY IN WINTER?
It would be better. The sunlight, in fact, although to varying degrees, has their deleterious effect on the skin all year round, in every season and any altitude. In winter, when the sky is clear, even to protect themselves from the sun on the plain is especially important for women with skin blemishes, capillaries open couperose; for the other not. However, after 30 years, almost all have at least one of these problems. The need to defend themselves in cities, where the skin is furthermore attacked by other agents such as smog and dust, and every day to prevent damage photo aging is fairly widespread. The manufacturers of cosmetics have got plenty of moisturizer on the market today already contain a solar filter. For those with sensitive skin is better to focus on medium-high protection (SPF 15) for dark-skinned may suffice an SPF 8.
