An ultra-violet part of a solar range is most potentially dangerous to skin. It is possible to get a sunblister not only in the open sun, but also being in a shadow where there are about 40% of ultraviolet rays, and also from artificial light sources: sunbeds, treatments by a quartz lamp.
Time of stay, safe for health, for the sun at each person differs, and the skin photosensitivity depends on phototype, that is.
Main dermatological phototypes:
1. Patients have light skin, eyes, red hair; even the minimum stay in the sun causes in them a sunblister, and suntan is never formed.
2. To patients are also characteristic light skin, light eyes and hair are more often, they hardly sunbathe and easily get sunblisters.
3. Patients have more often dark eyes and hair, swarty skin, quickly sunbathe, stay in the sun causes in them an easy sunblister which then turns into suntan, quite often very intensive.
4. Patients have swarty skin, these are dark-eyed and dark-haired people who easily sunbathe, without getting sunblisters.
5. People of negroid race.
Symptoms of Sunblisters:
Usually, the sunblister is got slowly and imperceptibly. Time of manifestation of sunblisters comes approximately in 12-24 hours. At easy degree of a burn the itch and erubescence begins, a swelling, blisters are absent. Sometimes body temperature increases.
The burn develops preferential on open parts of a body (a face, hands, women have shins). Reddening and unpleasant signs, most often, begin to decrease in 2 - 3 days, but they can sometimes last 7 - 10 days. Existence of pain, bubbles, change of the general state is characteristic of heavy degree of a sunblister: headaches, nausea, weakness, sleep disorder and appetite. The burn of a red border of lips is not excluded.
Sunblisters of easy degree pass without serious effects, heavy sunblisters lead to education is long not healing defects of skin: erosion and ulcers. But even the repeating sunblisters of easy degree are unsafe for the person and can lead to emergence of skin damages (sunblisters, photodermatoses, malignant new growths) of varying severity.
Influence of direct sunshine stimulates emergence on skin of various high-quality pigmental new growths, first of all a nevus and лентиго.
Nevus is available practically for each person. They can be located on various body parts and appear during the different periods of life. Their existence demands regular observation from the doctor-dermatoonkologa as eventually they can be transformed to malignant tumors of skin (melanoma), especially if the way of life and a profession of the person are connected with long stay under direct sunshine, influence of the ionizing radiation and the chemicals which are carcinogens. Lentigo appear at more mature age more often. Photodermatoses - skin diseases which arise under the influence of the sun. Carry solar urticaria, phototoxic reactions, polymorphic solar dermatitis, benign summer solar dermatitis, a lupus erythematosus and other diseases to them.
Reasons of Sunblisters:
People with the 1 and 2 phototype of skin are most subject to harmful effects of sunlight. It is known that some substances increase sensitivity of skin to ultraviolet rays. Those are some medicines. Tetracycline, tranquilizers, diuretic, hypotensive, antihistamines concern to them. Also chemical compounds used as fragrances, the ethers of some acids, oils used in the cosmetic and perfumery industry (bergamot, lemon, santalaceous, cedar) can cause photosensitivity.

It is also possible to apply effectively aloe juice, cucumber and tomato juice, the cooled black tea. Vinegar solution (1 tablespoon of vinegar on 1 liter of cold water) also well calms skin. Moisten with water or solution of vinegar a napkin and put it to affected areas. Moisten it is necessary constantly in process of heating. The second stage is moistening of skin because the cold compress will really take off a number of unpleasant effects, but if right after it not to moisten skin, it will dry up and the inflammation will amplify.
