Professional dermatologists have identified a link between sunburn appeared in various parts of the body and the initial development of melanoma (skin cancer). For the experiment were invited to test about a hundred applicants who were in the range of the set of ultraviolet rays. The range of the radiation was average, the wavelength from 315 to 280 nanometers. Once identified volunteers began and the experiment itself.
Participants had to endure six sessions of radiation, and then the scientists looked at the degree of sunburn on the back and buttocks people. After the "test" the researchers examined participants' bodies and found that the buttocks less responsive to UV exposure than the back. Both body portions formed of different shades of tan and depth.
As a result, experts have concluded that the skin takes uneven tan, which means that different parts of the body can be determined where the risk of skin cancer is greatest.
Do not abuse the tan, this leads to an acceleration of the aging process of the skin, as well as with a long stay under ultraviolet light, the skin loses its protective function. Tan on different parts of the body is not much different visually. Not near, rarely notice the difference hue. Do not worry if tan lay unevenly, after you stay on the beach in one position. But if, after sunbathing, your skin refuses to sunbathe, or were neoplasms (moles or dark spots), you should seek the advice of a specialist. Sunbathe right!
