dermatologists unanimously say the biggest cause of premature aging of the skin - immoderate tan!Despite the fact that the sun - a source of energy, which is vital for our skin, an overdose of ultraviolet radiation leads to the appearance of wrinkles, dryness and destructive processes on the surface of the skin.
What is tan?
From a biological point of view, is a defensive reaction to the scorching rays of the sun, which stimulates the production of melanin - the pigment of the skin.He gives it a golden hue.But the body needs a few days to fully adapt to a lot of sunlight.During this transitional period, limit your exposure to sunlight.
Different skin contains different amounts of melanin.Caucasian people never become chocolate-colored, no matter how much time they have not spent under the rays, because the amount of melanin in their skin lowest.In contrast, the dark-skinned people skin contains the largest amount of melanin.If you can not get a tan as you would have liked, try self-tanning - cream or aerosol, activating the skin melanin production process without the sun at all.In just a few hours you will receive a golden hue, which, however, washed away during the week.
To safely enjoy the sunlight without having to worry for your skin, use special means of tanning and follow the rules.

Sun Protection Factor - sun protection factor).The degree of protection of the skin from the sun or other cosmetic product depends on the protective factor.The label antisun cream, gel, oil or lotion, it indicates the number (from 2 to 40 and more).It shows how many times the sun exposure is reduced when using this tool.
We know that 10 minutes is relatively safe sunbathing with unprotected skin.Using a special cream that has, for example, the index SPF 12, you can safely bask in the sun for 2 hours (10x12 = 120).However, if you just want to sunbathe, then spend hours under the scorching rays simply do not make sense: a maximum of 50 minutes, the formation of melanin - a substance that is "responsible" for the tan - stops.
Lost in the winter melanin is reduced gradually.Therefore, in the first days of sun exposure should use funds with a high degree of protection - SPF 25, 30 or higher.
