Broadly understood, dermatitis is an inflammation of the skin. This name is given to many skin diseases. They occur, as a rule, when human skin comes in contact with an allergen and is a delayed-response allergic reaction. Therefore, contact dermatitis (10 mcb) is a kind of collective name for chronic or acute skin diseases. This group includes herpetiform, seborrheic, atopic dermatitis, etc. Each person has a predisposition to the manifestation of such allergic reactions.
What is allergic contact dermatitis
The irritant can act on the skin in two ways – through direct contact and through the blood. The first option is contact dermatitis, the second is toxidermy. For example, when skin inflammation appeared after applying the cream, then this is the first option, but after taking the pills – the second. Contact-allergic dermatitis does not appear so quickly, only after several contacts with the irritant. It may take up to several weeks to form an inflammatory reaction..
The inflammatory reaction of the skin is not related to the intensity of exposure to an allergen, which will not act in the same way on other people. The area of the disease will not necessarily coincide with the area of contact. Three forms of contact dermatitis are distinguished: acute, subacute, chronic. It can occur on different parts of the body, not excluding the eyelids, ears, penis, stomach.
With ordinary contact dermatitis, symptoms appear almost immediately after the first interaction with the allergen, and the area of skin lesion corresponds to the area of contact with the irritant. An example of this variant of the disease can be called chemical or temperature burns, scuffs, frostbite. With prolonged contact with an allergen, a chronic form of the disease develops. It manifests itself in the form of thickening, cyanosis of the skin, congestive edema..
Allergodermatitis in acute form externally has pronounced edema with bright reddening of the skin. At the site of the manifestation of the disease, bubbles appear that at some point open, but remain in the form of weeping erosion (wet). With the attenuation of inflammation of the skin, scales, peels remain, which is often called eczema. As a rule, dermatitis appears on the hands, waist, face, axillary region, earlobes. For a simple form of the disease, the following manifestations on the skin are characteristic:
- in places of interaction with an allergenic substance, the skin turns red, itching, swelling occurs;
- the appearance on the affected area of bubbles filled with a transparent liquid inside;
- when opening the vesicles, painful erosion remains on the upper layer of the skin;
- after the inflammation subsides, a yellowish crust remains at the site of the lesion.
Allergic dermatosis (allergic dermatosis) can occur under the influence of almost any substance. The cause of skin disease is not so much the pathogen itself as the individual susceptibility of a person to it. Experts still were able to identify a certain group of irritants that often cause the development of contact dermatitis:
- Nickel. Widely used for making buckles, jewelry, dentures, coins.
- Latex. Present in gloves, toys, condoms.
- Household chemicals. Various constituents of detergents, detergents, etc..
- Cosmetics and makeup.
- Hormones or antibiotics that are part of drugs (ointments, creams).
- Different synthetic materials used for sewing clothes.
- Chemicals, such as ink, paint, glue.
What does it look like
Externally, contact dermatitis can be confused with other diseases. Outwardly, it may be similar to fungal and infectious skin lesions or the herpes virus. In certain cases, it is confused with lichen planus or psoriasis, but they are easily excluded by a skin biopsy. An important factor in diagnosing the disease is the localization of the reaction site, a form of inflammation. The photo below shows how contact dermatitis looks like..
How and how to treat allergic dermatitis at home
The treatment for this disease necessarily begins with the fact that you need to get rid of the substance that causes dermatosis. The timely implementation of this paragraph largely determines how long allergic dermatitis lasts. If the substance that provokes inflammation on the skin is associated with professional activity, then personal protective equipment should be used. Treatment of the disease can be carried out using medications (tablets and ointments) or folk remedies.

Contact dermatitis can occur regardless of gender or age, but prevention, treatment will be different in children and adults. Therapy of the disease largely depends on the specifics of the perception of the course, so it is very important to carry out it under the supervision of a doctor. The specialist will monitor the body’s response, the course of the disease, monitor the effectiveness of treatment.
Treatment of contact dermatitis in adults has the same indications, the main of which is the elimination of the source of allergies, the appointment of a drug course. The difference in treatment is only during pregnancy. In this case, topical medications are prescribed. When using tablets of general importance, you need to pay attention so that there is no allergen in the composition. For health reasons, it is best to rule out pills that have effects on the digestive tract and stomach. A special diet is recommended..
Allergic dermatitis in children is very common. The reason is the interaction with an irritating substance. In newborns, the skin has a special sensitivity, and the immune system is not yet sufficiently developed, so the disease is especially painful. It is not very difficult to cure contact dermatitis in infants, it often passes by itself, but with symbiosis with other infectious diseases (staphylococcus), the course of the disease can be complicated.
Most medications are not recommended for use up to 6 years, so for the treatment of allergic dermatitis should increase the number of water procedures, walks in the sun. Be sure to find the cause of the disease, try to replace synthetic or uncomfortable clothes. For the time, refuse to use baby oils, use better boiled vegetable oil.
