Legends, myths, facts - everyone can contribute something to the topic of sun and sun protection. Everyone knows that sunbeams can be harmful to the skin and how important sufficient sun protection is. But does everyone know the right thing? Here are the most stubborn sunsets for an untroubled summer fun.
Myth 1: In sunlight, especially the UV-A rays and UV-B rays are dangerous
That's not true. According to scientific findings of the institute for environmental medical researches in Duesseldorf, the infrared rays of the type A, which are 30 per cent in the sunlight, are injurious to the skin: They penetrate deeper into the skin than UV-A-rays and UV-B-rays and set up a cell damage cascade there Gears leading to skin aging. Modern sun protection must therefore also contain an active complex against infrared A radiation.
Myth 2: Pre-tanning in the solarium protects the skin from the summer sun
That's not true! It is not the beautiful tan that protects against harmful UV radiation. These can only be selected UV protection filters. In addition, dermatologists rate the tanning on the tanning bed as very questionable.
It is better to prepare the skin for the sun, for example with sun capsules. They support the skin by radical scavengers and cell protection vitamins in the defense against sun damage. In particular, sun allergic people benefit from a preparation for the sunshine season.
Myth 3: In the shade sun protection is superfluous
That's not true! A large part of the sunlight and thus the harmful radiation is reflected, for example, from the sand or water - umbrella, hat or a large tree hold only little radiation. Therefore, it can also come in the shade to a sunburn; adequate protection is therefore also required there.
Myth 4: Sunscreen must be well massaged
That's not true! The cream or lotion should be gently applied as a film and should not be massaged firmly. British researchers found that after vigorous massaging of the sunscreen in terms of protective effect, there is little difference to no skin not creamed. The researchers suspect that rubbing too much of the cream in sweat glands and wrinkles accumulates or the UV filter changes its properties by penetrating the skin.
Myth 5: Lying in the sun all day - no problem with Sunblocker
That's not true! So-called sunblockers, ie products with a sun protection factor higher than 20, absorb most of the UV radiation. However, a part also penetrates into the skin and causes cell changes there. Even with a high SPF you should not be "forever" in the sun.
An EU Commission has even banned the term sunblock, as it may give consumers the wrong impression that this product provides 100% safe protection against UV rays. Basically, different skin types need different sun protection. Fair-skinned types need a higher sun protection factor than dark-skinned, allergy sufferers need a particularly gentle sunscreen and children one that is tailored to the special needs of the delicate skin.
Myth 6: Clothing protects against the sun
Is only partially true! The sun's rays can also penetrate through fabric, especially in light, loose clothing. For example, a white cotton T-shirt has an SPF of only 3 to 4. The darker the clothing, the stronger the protection from the UV rays. There are also special sunscreen clothing that is impregnated with sunscreen substances and almost no UV and IR-A radiations enter the skin.
Myth 7: Sunburn on the scalp can only get men with bald heads
That's not true! Everyone can get sunburn on the scalp. Particularly at risk is the area at the apex or hair roll. Therefore, the scalp should be protected from the sun's rays. If you do not want to wear headgear, it is best to use sun sprays that apply UV filters with a fine mist and do not grease them.
Myth 8: After-Sun products are superfluous
That's not true! Sun-damaged skin needs a lot of moisture. A special after-sun care also contains soothing substances such as bisabolol, panthenol or jojoba oil. Apres products with regeneration enzymes can even repair mild sun damage to skin cells.
Myth 9: Neurodermatitis may not be in the sun
That's not true! Sun can even significantly alleviate the symptoms of eczema. Also important here is the right sunscreen. The dry, sensitive skin should not be burdened by cosmetic additives, such as perfumes, dyes and preservatives. These can trigger inflammatory reactions, possibly exacerbating the skin disease. Better are dermatologically developed sunscreens that have been tested for good compatibility in atopic dermatitis.
Myth 10: The sun's milk from the previous year can no longer be used
That's not true! Sun filters and other important ingredients last longer than a year. Keep the leftovers in the fridge. High quality sunscreens have an expiration date. For unopened products, durability and safety are guaranteed until that date.
