Causes and mechanism of skin disease

The main factor of the disease is the inadequate perception of the sunrays by the body. Skin becomes irritated, red, swollen, its structure is disturbed, and a rash appears. The essence of the trigger mechanism is as follows: free radicals, which are formed as a result of sunlight on the skin, interact with proteins. As a result, photosensitizers are synthesized, which activate the onset of an allergic reaction.

This type of disease is also called photodermatitis or solar fungus. A person feels discomfort, his plans for a summer tan are crumbling, he is disappointed, the flow of negative emotions can cause a depressive state.

The disease can affect both adults and children, regardless of gender.

Internal and external causes of solar dermatitis (SD) can be identified.

Internal (endogenous):

  • Violation of metabolic processes.
  • The presence of sugar disease, obesity.
  • Excessive accumulation of toxins, which adversely affects the normal function of internal organs (liver, gastrointestinal tract, kidneys). As a result, they can’t cope with their main task — to cleanse the body.
  • Long-term use of pharmacological drugs, especially antibiotics.
  • Disruption of the nervous system (stress).
  • Ingestion of tinctures, decoctions based on popular recipes with wild medicinal herbs, in particular, St. John’s wort.

External (exogenous):

  • using the cosmetics that can contain benzophenone, benzocaine, musk;
  • interaction with aggressive cleaning and detergent powders and gels;
  • use of some ointments and medical creams, which include components that are intolerable to humans;
  • contact with plants containing allergens, for example, hogweed.

Low immunity can be an incentive for solar dermatitis, especially this often happens after the treatment of severe chronic diseases. After all, the human body has received a significant dose of potent drugs, in particular, antibiotics, which do not have the best effect on the immune system.

Solar dermatitis is classified into such species:

  1. Phototoxic is expressed by redness, swelling. Rash turns into blisters, in other words, it looks like a burn.
  2. Photoallergic is a characteristic of people with a hereditary predisposition. Its feature is the ability to spread even to those places of the skin where the sun did not fall.
  3. Porphyrias — a failure of the body in the perception of ultraviolet rays, due to serious violations of the process of biosynthesis in the bone marrow and liver.

The nature of the disease manifestation

Like most skin diseases, the solar fungus has obvious symptoms expressed on the surface of the epithelium:

  • Noticeable swelling of individual sections.
  • Rash with intense itching.
  • Bubbles and acne may fester.
  • The patient feels worse, accompanied by weakness.
  • Bright red rashes appear in places affected by the sun’s rays (back, face, shoulders, arms, legs).
  • With the allergic nature of SD, a lesion of the dermis can also occur in places hidden from the sun.
  • Possible conjunctivitis, cheilitis.

When such a disease transforms into a chronicle, there are additional signs:

  • Change in pigmentation.
  • The skin becomes over dried.
  • Burst capillaries turn into vascular stars.
  • Skin pattern becomes too pronounced.
  • Suppuration of inflamed skin.

Persistent erythema (redness) characterizes the clinical picture of the disease. This phenomenon is able to hold for long months. If the degree of redness decreases slightly, then after another exposure to ultraviolet rays, it increases again.

A person with such signs is threatened with complications in the form of coarsening of the epithelium, the appearance of scars. The skin can become similar to the surface of a ripe tomato.

It is important to understand that inaction with such symptoms is fraught with irreversible processes.

Diagnosis of solar dermatitis

Considering such serious consequences, the first symptoms of the disease should prompt a person to consult a doctor. Special attention should be given to the case of the children’ disease because it is difficult for them to endure such unpleasant symptoms.

A general examination will allow the dermatologist to observe the obvious signs. The patient’s answers to questions related to his behavior, the characteristics of the organism and the way of life will help to draw additional conclusions. Thus, the collected information allows you to make a preliminary diagnosis. Dermatoscopy of skin lesions is required for its approval. As a result, the doctor states the presence of a photosensitization process.

Further, with the help of application tests, a type of substance provoking the activity of an allergic reaction is detected. Allergens are applied to the affected site in two layers fixed by a bandage so that they can act for 24 hours. After the expiration of this period, the strips are removed, one layer is covered, and ultraviolet rays are directed to the other. By comparing the condition of the skin, the diagnostician receives the necessary information.

For a more detailed examination, the patient is sent for laboratory tests (blood and urine), a Zimnitsky test, followed by studies of hormonal changes. In addition, a number of diagnostic measures are performed using special equipment:

  • CT and ultrasound of the kidneys, abdominal cavity.
  • Excretory urography.

In order to exclude a systemic lupus erythematosus which is similar in symptoms, a blood test is being conducted. They can determine the antinuclear factor, lupus anticoagulant, and C-reactive protein.

Features of the SD treatment

The first step in the treatment is to minimize the impact of solar radiation. The presence of pronounced symptoms suggests the need to eliminate exposure to the sun. Patients are recommended to wear clothes that protect against direct rays on the face, shoulders, arms, neck. With a mild form of illness, it is enough to wait for the symptoms to subside and gradually open the body to the sun’s rays in order to get the desired summer tan. However, to decide on this you have to be confident that the disease does not recur. Here you will need extreme caution and attentiveness.

Prescribing medications is an important part of the treatment program. The main ones include the following groups of drugs:

– antiallergic;

– antihistamines;

– antiseptic (lincomycin gel, chloramphenicol methyluracil ointment);

– restoring skin regeneration (Bepanthen, Panthenol);

– antibiotics are selected individually, relative to the identified pathology;

– sedative drugs in cases of increased emotionality and an unstable nervous system;

– hormonal drugs for severe forms;

– non-hormonal external remedies (Protopic, Skin-Cap, Elidel cream, Diphenhydramine, Fenistil, Dexpanthenol) to alleviate the itch and relieve irritation;

– ointment with drying properties (Zinc cream), that also has an antiseptic effect.

It is important to note that many of the listed pharmacological drugs are potent. As for antibiotics and hormonal, they entail certain negative consequences. These arguments prove once again how important it is not to make a decision on their use independently. Appointment of drug treatment is the exclusive prerogative of the doctor.

Traditional medicine recommendations

People’s advice on the treatment of skin diseases has gained fame long ago, thanks to the positive results of their use. But this is not a reason not to consult a doctor before using them.

Horse-chestnut

Mix finely grated chestnut with carrot, apply the resulting mass to the sore spot for 15-20 minutes. Continue daily until symptoms disappear.

Healing bouquet

Collect several types of medicinal plants (chamomilla, calendula flowers, St. John’s wort, Plantago) in the same proportions. Cook the decoction according to the standard of 1 tbsp. in a glass of water. Put the mix on the stove, bring to a boil, hold for 10-15 minutes at extremely low heat. Treat skin several times a day.

Hypericum ointment

Collect more inflorescences of medicinal plants, get half a glass of juice from them. Next, boil it to reduce by half. Add 4 parts of butter in the cooled concentrate.

Similar, a miracle oil is prepared on the juice of sea buckthorn or peach. Such a remedy not only heals the skin with solar dermatitis but also makes it supple and elastic.

Features of SD prevention

With a tendency to this kind of pathologies, you will need special attention to your own body. Increased responsibility falls on those who have already suffered such a disease because no one guarantees its return. No less attentive the parents should be because they are entirely responsible for their own children.

What is required for this? It’s simple. Do not tempt fate and not to get involved in sunbathing. If the desire to tan does not go away, it is advisable to use special creams, sprays and other agents with a sun protection factor (SPF, not less than 30-40). The market offers a huge range of creams and tanning lotions.

After a tanning session, it is imperative to apply a panthenol-containing moisturizing cream intended for use after tanning.

Another important preventive warning is to avoid applying makeup before going to the beach.
