Numerous studies and scientific research shows that there are three big mistakes that make the most. Those who have not yet addressed the issue of anti-aging know, probably not to be responsible in addition to smoking and alcohol, too many UV rays for premature skin aging.
In order to assess how intense the UV radiation, there is the so-called UV index. The definition of these values is uniform worldwide, also are valid for all skin types. While in Germany usually reaches values between 0 and 8, the UV Index in the tropics to grow to a value of 12. Since numbers most people say but not much, the UV index levels in the "low", "moderate", "high" and "very high" divided. In this case, the higher the value, the greater the risk of suffering a sunburn and the higher must be the sun.
Sunbathing, those who want to do something out of the area of anti-aging, not only pay attention to their skin types. Just as important, what is the actually measured UV index. Therefore you must first know what solar type you are. Officially there are four different classes.
The sun type 1 has the following features: He will never get brown and after a short sun burn. Most of this type is red-haired, pale, and has green eyes. He also tends to get freckles and age spots.
They belong to the solar type 2 in this case: While they may be brown, but only if you have enjoyed more sun exposure. They also have relatively frequent sunburns. Other features are that these guys usually have blonde hair and blue eyes. There is often also to freckles and age progressed to age spots.
For solar type 3, the following is characteristic: it is relatively well-brown, usually has dark blond or brown hair and brown eyes.
For solar type 4 you belong to, if: you have dark hair and dark eyes and brown are relatively well. Sunburn you get relatively rare, moreover, you are spared of freckles and age spots.
In order to know what sun protection you need, you can apply the following rule of thumb:
Sun Type 1: double UV Index + 20%
Sun Type 2: SPF = double UV Index
Sun Type 3: double UV index - 20%
Sun Type 4: double UV index - 30%
If a UV index of 5 is specified, this means to you when sun protection following:
Sun Type 1: double UV Index + 20% -> SPF 12
Sun Type 2: SPF = double UV Index -> SPF 10
Sun Type 3: double UV index - 20% -> SPF 8
Sun Type 4: double UV index - 30% -> SPF 7
