The skin is an integral part of the human body and is the largest organ of the human, which is visible to the eye. She plays the role of a kind of indicator, reflecting the status of all systems and organs of the body, protecting them from the penetration of infection and mechanical damage. Normally, skin diseases indicate that the function of internal organs violated or said about bad habits and unhealthy way of life of the patient. In turn, the skin disease can lead to significant consequences for the whole organism in general, if not in time to begin their treatment.
A variety of skin diseases caused by exposure to a large number of external and internal factors, the diversity of its functions, particularly of the skin structure.
The impact of exogenous, ie external factors is diverse. The chemical and physical agents lead to inflammatory diseases of the skin - dermatitis (abrasions, diaper rash, burns, etc.). Biological factors cause fungal skin lesions - fungal infections (mikrosporiya, athlete's foot), pustular disease - pyoderma (furunculosis, hydradenitis, impetigo), parasitic infestations (scabies, lice), viral skin lesions (warts, herpes).
Of great importance in the development of skin diseases have internal (endogenous) factors. These include:

Urticaria happens when a stimulus causes the cells to release histamine. Histamine, in turn, causes vasodilatation. The fluid accumulates under the skin, and produce large, red, often itchy blisters, called papules. Sometimes they are similar to mosquito bites. When urticaria such blisters usually appear just a lot, but they are different size from a pea to 4-6 cm in diameter. They usually pass quickly, in just a few hours. Reasons urticaria often remains unclear, but some people know that certain foods, beverages, or medications can cause their hives. Acute urticaria (eg, associated with taking the drug) can stay on the skin throughout the day. Chronic urticaria (often unknown origin) may last for weeks. Severe outbreaks of hives can be dangerous, especially if the papules appear on the lips or throat. In severe hives may even occur edema, dizziness and loss of consciousness.
Scabies. When scabies on the skin appear small, strongly itching blisters. The causative agent of scabies is the itch mite. Ticks live deep in the skin where the females lay their eggs. Within 5 days the eggs hatch new insects. Itch does not appear immediately, but after about a few weeks after the mites have settled on the skin. If you have symptoms of scabies, see your doctor. If you really scabies, the doctor will prescribe a lotion that kills the mites, and give necessary recommendations for prevention. All family members must also be used to prevent a special lotion. To relieve itching, you can use non-prescription antihistamines. Be sure to thoroughly wash in hot water all bedclothes and other hygiene items.
Scars. Scars are traces of skin left after the accident, surgery or disease. Scarring is a natural process of wound healing, when the replacement tissue fills the damaged area. The more serious the damage is, the longer the wound heals and the more likely scarring. Scar formation, size and color depend on the location and age of the skin. In young skin scars heal faster and leave fewer traces. The skin in the lower part of the face is quite thin, so scars in this region tend to be more noticeable. At the beginning of the scars look darker and wider, then gradually fade. To improve the appearance and self-masking can use cosmetics. To improve the skin condition can be used OTC products containing allantoin, silicone and other substances.
