Sensitive Skin
Although the skin is responsible for regulating body temperature and to perceive the stimuli of pain and pleasure, his first objective is to protect the body from external agents that can cause harm. Thus has sensory receptors located in the layer called the dermis, which are one of the main sources of information about the outside world and activate mechanisms that prevent the danger.
It is very fine nerve fibers at the slightest stimulus move immediately signal after being received by the brain is manifested as irritation and itching, mainly.
However, it is important that each person has a different skin sensitivity, ie not all respond equally to agents or attempting to cause harm, there could therefore speak of conditions including:
Dermatitis.
In practical terms this is called a simple way to skin inflammation, which can alter their susceptibility. Occurs when contact with irritating substances contained in plants, hair dyes, cosmetics, deodorants, perfumes, soaps, detergents, synthetic fibers, products for hair removal, metal jewelry, as well as by the action of a drug or food ( milk, eggs, fish and seafood, among many others).
Faced with a problem of inflammation of the skin suggests the application of creams and ointments counter indicated for that purpose, but have abnormalities in the immune system (one that protects us from attack by viruses and bacteria) require the help of a dermatologist, who may recommend medical tests and more aggressive treatments.
Allergies.
Some people respond in an exaggerated manner to substances that are sensitive-called allergens, which are harmless to others, because you are born with a genetic predisposition to it, pollen, dust, humidity, animal hair, cosmetic, chemical, or some textiles, among many others, are elements that can be allergic.
The allergens are introduced to eat certain foods or medications, inhalation or through skin, causing the body to produce histamine, a substance responsible for the itchy, watery eyes, hives, nasal obstruction, headache and dizziness, among other symptoms. Special mention should be made of insect Cadur pi, since the immune system from some people may develop an allergic reaction to the venom injected.
Before an allergic reaction such as those mentioned earlier, we recommend taking an antihistamine. It is obvious to avoid contact with substances to which they are allergic but unless you know what cosmetics avoid using old or borrowed, read food labels and ask what ingredients used in restaurants to prepare food, to preventing the use of one that may cause an allergic reaction.
When you know that can be caused by insect bites, you should use repellents on skin and clothing. The case of any allergies in addition to skin hypersensitivity reaction there is any unexpected, such as difficulty breathing, dizziness or swelling of face or hands, should go immediately to the allergist, medical specialist in the treatment of allergies.
Mycoses.
Infection caused by fungi, microorganisms that are languishing in the outermost layers of the skin, characterized by causing redness, spots, itching, peeling, irritation and cracking, affecting areas like scalp, feet, vagina, English, axillae and nails. Importantly, easily transmitted by contact with infected live or surfaces and objects contaminated areas of friction as axillary folds, breast, inguinal and interdigital are those most frequently affected.
In some cases cause no symptoms, only produce spots, rounded, reddish or white, and are difficult to eliminate them, usually make their presence known on the trunk and thighs.
Now, in addition to wet weather, lack or excess of hygiene, tight clothing and footwear, other factors for the development of fungal infections, such as antibiotic treatments, use of soaps too acidic which alter the level of acidity (pH) of the skin and diseases that disrupt the immune system (one that protects us from external aggression), among which are diabetes and cancer.
The main fungi involved are called dermatophytes, belonging to the genera Trichophyton, Microsporum, Epidermophyton, Malassezia furfur and Candida albicans. According to the area where they are located, and the pathogen, indicating the most appropriate antifungal.
Eczema.
It is characterized by an outbreak of red welts on cheeks, wrists, knees and the inside of the elbows, which causes intense itching, irritation, tiny ulcers and scaling. Its appearance is related to the effects of the sun, wind, and thousands of chemicals that come in contact with skin, why is synonymous to some sources of contact dermatitis, and which will be mentioned later.This will occur after two months of age, usually in people with dry skin.
One way to avoid the appearance of eczema is to use sunscreen whenever exposed to the sun king, white-skinned people should choose a sunscreen, since your body has less melanin (natural pigment of the body that defends us from sunlight) than those with brown skin or black.

Its origin is unknown, but its appearance is often associated bacterial infections, genetic factors, intense emotional states and stress. Other actors that influence their occurrence are beatings, burns and wear tight clothing.
There are other actors that influence the skin sensitive, such as stress, hormonal changes (for example, when presented the menstrual period), environmental contaminants and climate change, aging, strict diets, drinking little water consumption alcohol and snuff, and little sleep.
These factors can be avoided, but also be very useful to follow balanced diet that includes minerals, proteins, vitamins, carbohydrates and fats, plus eating 2 to 3 liters of water daily and skin care treatments that provide protection, moisture and nutrients.
