10 common myths about sunburn, which is time to debunk (about the clouds, carrots and not only)
Did you know that you can’t use a sunscreen for several seasons in a row? And that the foundation with SPF can not protect you from the dangerous effects of the sun. The sun is not a very frequent guest in our latitudes, and therefore Russians still have a careless attitude to the problems of protecting the skin from the sun. And it seems that all the recommendations of doctors exist for someone else, but not for the harsh, hungry in the sun over the long winter Russians. Dermatokosmetolog Evgeny Ikonnikov debunk the most popular myths about sunburn and sunscreen.Myth 1: Sunscreen should be used only by people with a light skin type.
It is important to remember that under the influence of ultraviolet radiation, we not only catch fire. UV radiation is divided into three spectra depending on the wavelengths that can penetrate the skin. Without caring for its protection, you allow these rays to stimulate the production of collagen-destroying enzymes. This leads to photoaging of the skin, the development of hyperpigmentation and vascular reticulum. UV radiation carries with it much more serious consequences, for example, the development of malignant tumors, the most dangerous of which is melanoma. So everyone, regardless of the skin phototype, should use a cream with high protection from the sun throughout the holidays. And do not neglect the daily sun protection in the summer, including in his hometown.
Myth 2: The skin can not burn in cloudy weather
The sky, overcast, and the cool breeze, pleasantly blowing the skin, can easily confuse holidaymakers. Do not forget that clouds pass up to 80% of ultraviolet radiation, so you can get burnt and in cloudy weather.
Myth 3: It is enough to apply sunscreen on the skin once a day before going to the beach.
The cream should be updated on the skin every 2-3 hours, regardless of whether you were sitting on the beach or actively building sand castles. After immersion in water, 90% of the funds are washed away from the body, and sea water even affects waterproof products, reducing their protection. Therefore, after bathing, especially not to be lazy to re-apply a protective cream. If you use tonal or day cream with SPF-factor, then you should understand that they “work” also only for a few hours, and not at all all day.
Myth 4: A single sunscreen is enough for several seasons.
Everything has a shelf life, and sunscreen is no exception. Most of these tools can be stored no more than a year in the clear. After the expiration of this period, they lose their protective properties. Moreover, the chemicals in their composition, after the expiration date, can change their structure and properties, which, in turn, can have a negative effect on the skin in the form of allergic dermatitis or even photodermatitis.
Myth 5: Apply sunscreen only on exposed areas of the body.
UV rays are so strong that they can penetrate through the glass of buildings and cars. That is why it is important to apply sunscreen all over your body, no matter how many skin areas your clothes cover. A regular shirt can protect you from sunburn, but not from photo-aging.
Myth 6: Before you go to the sea, it’s worth going to a tanning bed to prepare your skin for tanning.
Yes, of course, arriving at sea with already tanned skin, you significantly reduce the risk of burning. But we must remember that the lamps installed in the solarium, have no less intense and harmful effects on the skin than the sun. Also, do you know exactly when the tanning bed was being serviced with lamp replacement? After all, if they are not changed in time, they become very dangerous for our skin. The negative impact of the emitted UV lamps by the lamps will greatly exceed all permissible norms.
Myth 7: If there are a lot of carrots, then the tan will be more beautiful.
Partly, right, but not quite. Indeed, carotenoids contained in carrots and giving it an appetizing orange color can have an indirect effect on pigment-synthesizing cells. But when exposed to the sun, these substances are more antioxidants and protect skin cells from the harmful effects of UV radiation. It is not obligatory to eat kilograms of carrots – modern bioadditives taken 1-2 weeks before the holiday and during it contain the necessary concentration of carotenoids. So there is no need to eat carrots for breakfast, lunch and dinner for a beautiful tan.
Myth 8: If you apply a tool with a maximum SPF, then you can not be afraid of being in the sun for a long time even during the peak of solar activity (noon).
The SPF level indicator (for example, SPF 20) is determined by the minimum erythemal dose. This is the duration of exposure to the sun, at which redness may appear on the skin.
