"We are born within certain temperatures, our skin adapts to sun exposure, typical for this latitude," believes Liene Metusela. In her daily practice, she sees the impact on the skin the habit of tanning, because the skin "remembers" everything that happened to her. Dermatologist believes that you can sunbathe, observing all the rules of protection, because the sun brings joy and positive emotions. However, everything needs to be done in moderation in accordance with their skin phototype. Going in the sun, we must not forget about protective creams and time — to take the necessary vitamin D can be until 11:00 and after 16:00.
There are several classifications of phototypes. In Europe we use mainly four phototype. Accordingly, the first phototype typical redheaded, freckle-faced people with white skin who burn easily and never tan appears. The second type of skin typical blond, blue-eyed and green-eyed people who tan appears slowly and the skin sensitive to the sun. The third type belong to the owners of slightly darker skin who have brown eyes brown hair freckles rare, and during the summer period produces a steady tan. People of this type can burn after prolonged sunbathing. Finally, the fourth characteristic phototype people with dark skin, dark hair and eyes, no freckles, plus they never burn.
Dermatologist encouraged to think about the skin, especially during the holidays when many people travel to warmer climes, and Islands that are closer to the equator, where the sun acts faster and stronger ultraviolet radiation, and sunburn daily and are long lasting. Greater risk of various skin lesions in people after 40 years, starting when age-related changes and aging of the skin. You need to understand that the top layer of skin — the epidermis is restored within a month, therefore, obtained during rest the sun will inevitably disappear, if it is not supported.
We should not forget about the children. In infants and young children melanocytes are not yet ready to work — the production of melanin, therefore, children it is very dangerous to be in the sun.
From the point of view of the human structure, in the epidermis there are various types of cells and each has its own task — to protect against the adverse effects of the environment and ultraviolet radiation, to indicate illness and malignant changes. Due to the effect of UV-radiation damages the genetic information of the cell nucleus and at the same time break down the immune cells that can cause skin cancer. The most dangerous is melanoma, as it quickly grows and develops, its effects are negative. It can appear on practically intact skin or changing moles. Melanoma can be of different shapes and colors.
Even on the skin can form basal cell carcinoma first appears as a small brown. When they go, their places to form new crust, which subsequently begin to bleed and expand. Relatively malignant cancer is squamous cell carcinoma, a precursor of which can be dense, difficult to discharge, peeling of the skin on the open places, especially on the face and frontal part of the head, to a greater extent exposed to the sun.
Without attention do not leave skin lesions that appear due to aging, the so-called "senile warts". They appear because of the uneven division of the skin, creating a seal. In most cases these warts are aesthetically unpleasant effect, and patients want to get rid of them.
It should be recalled that after the end of the season, sunbathing need to explore your body and determine if there has been any skin changes: if there are any new lesions, do not change color, size or shape of moles to see if itching or bleeding. And, if there were suspicions, you must visit a dermatologist to examine skin education with the help of a Dermatoscope.
