Sunscreens advertised recently as primary protection from the scorching sun and the risk of skin cancer, but many experts believe that their performance is more than twice as exaggerated due to the disease of all types of skin cancer. Insufficient amount of damage means infrequent reapplication and the wrong choice of means - these are some mistakes that people make.

What about the environmental aspects?

Studies have shown that some components in sunscreens can be harmful to our health and the environment. So it is now the beginning of summer, it's time to learn about the pros and cons of the use of suntan lotion.

Exposure to solar energy UV radiation can lead to premature aging Internal and external aging: it is necessary to think in advance   and in the worst case, skin cancer Skin cancer: causes and prevention . Two forms of UV radiation, which fall on us from the sun, sun lamps and tanning vertical, the rays of the spectrum A and B.

• Rays And, although they are not as powerful as the rays penetrate deeper into the skin and cause photodamage. These rays have a direct relationship with the occurrence of malignant melanoma, the deadliest form of skin cancer.
• The UV rays affect the outer layers of the skin, causing darkening of the skin and burns. These rays can cause the development of basal cell carcinomas, two forms of non-malignant melanoma. Both types of beams 90% are the cause of the symptoms of premature skin aging, including wrinkles.
• SPF indicates as needed solar energy (UV radiation) to provide a tan protected skin relative to the amount of solar energy necessary for sunburn on bare skin. As the level increases the degree of protection.

There is a misconception that the SPF indicates the time in the sun. This is not true, as the SPF does not refer to the time of exposure to the sun, and to the amount of sun exposure. Although the amount of solar energy is related to the time of exposure to the sun, there are other factors influencing the amount of solar energy, such as the intensity of the sun, skin type, amount of funds deposited by the sun and the frequency of repeated its application to the skin. Therefore, the use of tools with SPF 30 does not guarantee that you can lie in the sun thirty times longer without risking burn.

Remember that SPF applies only to the rays V. Do not have an effective means of exposure rays A.

You may have heard that exposure to the sun - the best way to get your daily dose of vitamin Vitamins for everyone   D. Research shows that most people get enough vitamin D in the spring, summer and autumn, when they arrive in the sun, doing business as usual.

The only way to determine whether the agent provides protection from the sun rays A and B - is to look at its components. There are 17 approved active ingredients used in the composition of sunscreens. These filters are divided into two broad categories: organic / inorganic chemical and / physical.

Most organic UV filters: they form a thin protective layer on the skin surface and absorb UV radiation before it penetrates into the skin. Inorganic vehicles - insoluble particles that reflect UV light from the skin, such as zinc oxide or titanium oxide. Most products contain a mixture of organic and inorganic active ingredients.

Selecting means

Choose tools with SPF 15 or higher plus a combination of: a stabilized avobenzone.

It is those ingredients in sunscreens, which provide protection from the sun may also have harmful side effects. Some chemical constituents in sunscreens may get into the bloodstream as a result of topical application, that can be dangerous if they accumulate in the body or the environment.

Research has shown that four out of five of protection from the sun provide insufficient protection from the sun or contain ingredients that are in danger. In addition, there is information that ingredients such as parabens and benzophenone may act as human estrogen and disrupt the hormonal functions of the body.

Other components, such as zinc oxide and titanium oxide, popular in sunscreens and skin giving a whitish hue, were reduced to nanoparticles in order to reduce their visibility on the skin. Scientists worry that these tiny particles penetrate the skin and call free radicals. They agree that little research to ensure safe use of nanotechnology in the production of personal care products.

Regardless of the research, it is important to remember that sunscreens are not considered as a replacement of measures for avoiding exposure to the sun, but only means that sometimes it helps if you use it along with the precautions in the sun.
