Skin Rash (Eczema) – Causes, Online-Diagnosis & Treatment

A skin rash can occur in many different forms in various parts of the body and has numerous causes. It manifests itself, for example, in red pustules and spots, blisters, nodules or dandruff. This guide provides detailed information about possible triggers such as allergies, skin diseases, infections or medication. You can also send photos of your rash to a dermatologist via our Homepage. The dermatologist will send you his online diagnosis of your individual rash and a recommendation on what you should do about it.

Skin rash has many faces – here a relatively common one: Urticaria.

What happens in case of skin rash?

You can rely on your skin. It “speaks” a clear language not only for physical complaints, but also for inner, mental processes. With excitement or shame the person blushes, in seconds of shock he bleaches, with fear the hair straightens up and he gets goose bumps. In case of impurity or stress, spots develop, in case of diseases caused by viruses, bacteria or fungi, the surface changes. It leads to redness, inflammation, dandruff, itching and other symptoms. The skin is not only the largest organ of the body, but also the protective coat and signaliser when something is wrong with health.

Because of its area of about two square meters and its property as a body shell, the skin is also an ambassador and helper of the human immune system. It protects the organism from sunlight and pathogens, from overheating, dehydration and excessive heat loss. With its approximately two billion cells, it is not only extremely exposed to external influences, but also shows clear reactions to negative activities within the body, which often lead to unpleasant changes.

These changes usually cause some form of skin rash that may cover smaller or larger areas. Doctors call the skin change efflorescence. The skin rash itself is called exanthema. It can manifest itself as white, reddish or brownish spots, purulent pustules or nodules. Exanthemes form garlands, spots, circles or hives. The latter are light to pink-coloured, small soft swellings, which occur for example in hives. In some diseases there are vesicles filled with fluid.

Forms of skin rash and possible complaints

form and appearance of a rash are often very typical for a disease and indicate a certain cause at first glance. However, it is still important to know when and where changes in the skin occur, what their development is and whether any further symptoms may occur.

skin rash naturally appears on the surface and is characterized by a varying degree of spreading. Sometimes net-shaped structures or structures that look like maps are formed. All parts of the skin can be affected, with the exanthema appearing at particularly typical sites in many diseases. These can be the hands, feet, fingers and toes, the elbows and arm bends (for example in neurodermatitis) as well as the inside of the forearms, the legs and knees. Other diseases manifest themselves in skin rashes on the face, chest and back, in the groin and genital region or on the buttocks. Depending on the stage of development, initial redness and blisters can soon develop into crusts, scales, cracks and wounds.

The most frequent accompanying symptom of skin rash is a more or less severe itching, often with fatal consequences. Most people – especially children – then react with scratches, which further burdens the exanthema and leads to even more severe inflammations. The affected areas of skin can also be burning, painful and very warm. If rashes form on the mucous membranes in the mouth, nose and throat, they are referred to as enanthema.

In some diseases other symptoms such as fever, sweating and nausea occur. Or it comes to general and lymph node swellings, cough and breathing difficulties. For example, acute reddish spots with simultaneous fever in children indicate typical childhood diseases such as measles, rubella or chickenpox. A particularly dry skin or inflamed skin areas with strong itching are usually a sign of neurodermatitis.

wound roses in turn cause symptoms such as reddened skin with swelling of the legs. Skin rash due to side effects of medication and other causes can be seen, for example, in thickened red and itchy spots. These often extend across the chest and back or on the inside of the legs and arms.

These are just a few examples of the many causes and forms of skin rash. More details will follow below.

When should you go to the doctor if you have a skin rash?

Not every skin rash is the result of a disease or infection. A new, scratchy sweater or cosmetic cream can also irritate the skin. Here it is helpful to do without the product or change the garment. If an insect bite is present, cooling or an ointment is usually sufficient. The itching and the redness around the bite will disappear by themselves after a while.

Caution is required, however, if a strong allergic reaction occurs after an insect bite. Some people may experience life-threatening situations in which only the immediately notified rescue service can help. In case of weaker reactions, a doctor should be consulted at least promptly. However, there is also the even more convenient option of sending a photo of the affected skin area and information about the symptoms to in order to have it checked online. An experienced dermatologist such as Dr. Wiebke Sondermann from Essen may already be able to give advice on the type of skin rash.

A visit to the doctor or an online consultation is recommended by professionals:

  • if the origin of a skin change is unknown
  • in case of a sudden and violent skin rash
  • in case of severe itching, swelling and pain in the corresponding area
  • for additional symptoms like fever, shortness of breath, trembling etc.
  • in the case of a gradual but distinct spread of the rash over a longer period of time
  • when the skin changes show up intermittently (with phases without symptoms in between)
  • when the rash itself changes and forms pustules, nodules, blisters or scales
  • when bleeding occurs at the red spots
  • when infants and children are affected

If you want to see a doctor, the first contact person is your family doctor. He can either treat the patient himself or refer him to a dermatologist or other specialist if there are certain suspicious facts. Children with a skin rash should first be presented to a paediatrician.

Which triggers cause skin rash?

Exanthema are mostly based on infectious diseases or are expressions of defensive reactions against internal processes that are noticeable on the skin. However, they can also directly affect the skin. The most common triggers are viruses, bacteria and fungi. In addition, allergies, infectious skin diseases and side effects of medication can be responsible. Inflammatory, non-infectious diseases such as dermatitis and eczema, which are based on internal and external factors, also play a not insignificant role. In these cases, certain vascular inflammations, autoimmune or systemic diseases often play a major role.

If the triggers are internal processes – such as bacterial or viral infections – the symptoms appear on both sides. If the changes only occur on the outside of the skin, external pathogens and stimuli are also responsible. This applies, for example, to fungal infections and contact eczema. But there are also exceptions and overlaps.

The mental state of a person also influences the skin condition. Strong mental stress, bereavement or stress can favour or intensify skin rash. Among experts, so-called idiopathic rashes are also known to occur without an identifiable trigger.

Overview of common causes of skin rash

The following sections describe the most common causes of skin rash.

1. Infectious diseases

Infectious diseases caused by viruses or bacteria often cause skin rash.

Viral infections in children

Typical childhood diseases based on a virus infection are chickenpox, measles, rubella and three-day fever. In addition to fever, they cause very specific skin rashes that are clear to the physician. The hand-foot-mouth disease also mainly affects younger children and is caused by type A Coxsackie viruses. In addition to high fever, aphthae – milky yellowish formations on the gums and oral mucosa – as well as nodules and blisters on the hands and feet are characteristic of this disease.

Viral infections in adults

A typical and recurrent infection in adults with skin rash is caused by herpes-zoster viruses. The result is painful skin areas on the face, ears, chest and back (shingles). Herpes simplex viruses are responsible for the well-known cold sores on the mouth and lips, which do not blossom at all in some people despite infection, but also repeatedly in others. Herpes genitalis viruses, which cause an itchy skin rash in the genital region with redness and blisters, originate from the same environment.

Peiffer’s glandular fever is caused by Epstein-Barr viruses and manifests itself in redness and hives with simultaneous itching. In part, a parallel antibiotic therapy also plays a role here.

An inflammation of the liver caused by viruses – so-called viral hepatitis – can trigger a skin rash, which, however, passes quickly. This occurs in addition to flu-related symptoms, jaundice, pressure pain on the right upper abdomen, nausea and other complaints such as joint pain. Chronic hepatitis sometimes leads to rashes on the palms of the hands and soles of the feet, accompanied by severe itching.

Bacterial infections

Bacterial infections that cause skin rash include scarlet fever in children, second stage syphilis, and Lyme borreliosis. In Borrelia infection by a tick bite, the rash is a characteristic annular redness that spreads around the small bite wound..

Other infectious diseases

Not only in Europe “native” pathogens can cause skin rash. Tropical diseases such as dengue fever are often accompanied by exanthemas, although symptoms similar to influenza predominate. These include high fever and severe pain in muscles and joints. As a general rule, a doctor should always be consulted if symptoms of an illness occur after a trip. The doctor must also be informed of any previous stay abroad. This can support him in his diagnosis.

2. Side effects of drugs

medicines are specifically designed to help people in healing processes. However, some drugs are unfortunately among the main causes of skin rash along with infections. Also in these cases there are very different appearances like nodules, pustules, spots or vesicles filled with liquid. The itching that is often typical for exanthema can also occur.

If the side effects are not hypersensitivity or allergy, the skin rash often breaks out late. This can be one or two weeks after first intake or even after the end of therapy. Exanthema may also occur when a virus infection is present and drugs such as the painkiller acetylsalicylic acid are taken. In such cases it is often difficult to determine the cause. It should also be borne in mind that older people in particular react more sensitively to drugs than younger people.

The following overview lists drugs that often cause rash reactions:

  • antibiotics (penicillin, sulfonamide and others)
  • Preparations with cortisone
  • cancer drugs
  • Diabetes medicine (e.g. Glinide)
  • anticoagulant
  • Antirheumatics (e.g. acetylsalicylic acid)
  • Gold salts as rheumatherapy
  • Gouty medication
  • Antipileptics
  • water-washing drugs (so-called diuretics)

The problem of skin rash can also be caused by herbal preparations. In some cases monk’s pepper leads to itchy exanthemes. Coriander and caraway oil cause allergic skin reactions in some people. If products containing the well-known St. John’s wort are taken, direct exposure to sunlight should be avoided, as this can cause symptoms similar to sunburn.

Beware! If skin changes such as blistering or redness occur immediately after taking a medication, a doctor or even the emergency services must be notified immediately. This is especially true if fever, swelling, shortness of breath and other unusual symptoms are added. Such violent reactions can be life-threatening. If a skin rash does not become noticeable for several days, a visit to the doctor is also recommended. However, you should not stop taking the medication or change the dose yourself.

3. Skin rash due to allergies, intolerances and harmful substances

Anallergens are certain substances that are actually harmless but in some people cause immune reactions. Such allergies often manifest themselves in the form of skin rash accompanied by other symptoms such as itching, coughing and colds. Allergens either affect the skin directly from the outside or via the mucous membranes of the respiratory and digestive tract. This enables them to enter the human body, for example as components of food or as air particles.

contact eczemas and other inflammatory reactions

Inflammatory skin reactions are often a sign that the skin has to defend itself against harmful and aggressive substances. When it comes into contact with them, so-called contact eczema develops. They can be caused by allergies, but not necessarily. An allergic skin rash can also be caused by substances that are absorbed by the body and act from the inside.

Eczema, which is not based on an allergy, shows a spectrum from irritated (irritative) to toxic, i.e. more severely damaged skin. The triggers are numerous substances, including toxins, i.e. harmful and toxic substances. Previously existing skin diseases can also promote the formation of contact eczema.

Concrete examples are e.g. sharp detergents, latex gloves or certain plants. Frequent use of these leads to reddened, itchy skin rash, mainly on the hands, in some people. However, other parts of the skin may also be affected. In the case of violent reactions, blisters sometimes form which are particularly itchy and can also burst open. Then scaly surfaces often form and the skin may become encrusted.

If there is no contact with the triggers, the skin usually recovers completely. Conversely, contact eczema can become chronic. This usually happens when the skin is exposed to the harmful substances for long periods of time and does not have time to heal. The affected areas expand and start to flake. The skin there feels very dry, hardens and forms fruits and wrinkles.


Sunlight can cause allergic reactions in people who are hypersensitive to certain creams or perfumes. They manifest themselves in the form of heat pimples, but also stronger rashes with reddened skin, blisters and nodules. When taking certain medications, some people need to protect themselves from the sun because a combination of these two factors can cause photoallergic reactions. A common sunburn is also an exanthema and falls under the category skin rash.

An important note

In many cases an allergic skin rash develops as hives (medical urticaria). Symptoms are itchy, fluid-filled blisters and hives. Sometimes there are also larger swellings on the hands, feet, face or genitals. These phenomena are known as angioedema. If they occur in the mouth and throat area and hinder breathing, they can become life-threatening.

Caution with shock reactions

It is well known that some people react particularly violently to certain allergens. This applies, for example, to the insect venoms of bees and wasps, which can lead to a so-called anaphylactic shock. In such a case, there is a danger to life!

Signs of a shock reaction are strongly itchy, burning hives on the palms of the hands, soles of the feet and other parts of the body. This can be followed by shortness of breath, vomiting and diarrhoea, tachycardia, drop in blood pressure and a clouding of consciousness.

If these symptoms are present for a shock, a rescue service must be called immediately. In the case of an insect bite, for example from a bee, the sting must be removed immediately. Persons affected should then undergo a detailed allergy test or special immunotherapy. Hyposensitization can prevent new shock reactions. Doctors recommend that these patients carry an emergency kit with cortisone and an antihistamine with them at all times.

4. skin diseases as cause for rashes

The majority of skin diseases result in typical changes of the organ. They are usually limited to certain parts of the body, but do not necessarily correspond to the medical picture of skin rash. This applies, for example, to skin tumours or warts. Exceptions are Paget’s tumor or Kaposi’s sarcoma in tumors as well as dell warts.

Also not to belong to the exanthemes:

  • pigment disorders such as age spots or vitiligo
  • vascular disorders or blood diseases that manifest themselves through skin bleeding (petechiae or purpura diseases)

However, in some vascular inflammations such as the purpura pigmentosa progressiva or the purpura Schönlein-Henoch, rashlike symptoms occur.

In general it can be said that only some skin diseases cause a typical skin rash. This usually occurs very suddenly on the surface, then spreads on both sides and spreads further from the starting point. Exanthemes of this kind often change in different ways.

The most important skin diseases, which also manifest themselves as skin rashes, are briefly presented here.


Neurodermitis is a chronic inflammatory disease with skin rash on various parts of the body. It mainly affects children from infancy onwards, and more rarely adults. A detailed description of this skin disease, its causes and symptoms, its diagnosis and therapy options can be found in the special guidebook on this website.

Psioriasis, Lichen and Lichens

The medical term psoriasis refers to the skin disease psoriasis. This is manifested in sudden changes in the skin. This results in reddishly inflamed, mostly itchy plates with whitish-silvery scales on the surface.

The category lichens (medical lichens) includes various clinical pictures. One of them is lichen ruber planus, the nodular lichen, a rare but chronic disease. It affects the skin and mucous membranes in larger areas or groups and forms reddish, itchy knots that are sometimes striped white.

The affected parts of the body include the inside of the wrists and ankles, the lower legs, the areas above the ischium and the outer genitals. In some forms the hair and nails are also affected. The cause of nodular ligament is not known, but medication may be the cause. Women suffer from it more often than men.

The pus psoriasis (impetigo) is found especially in children. It is caused by bacteria of the Streptococcus or Staphylococcus type and is contagious.

Pityriasis rosea is an inflammatory disease and often affects people in the middle phase of life. It occurs acutely for unknown reasons, but heals itself in most cases. Initially, a typical skin rash forms in the form of a reddened, scaly plate in the middle of the body. Then an itchy exanthema appears in episodes, which can extend from the trunk to the thighs and upper arms.

Another skin disease with unexplained origin is the rare pityriasis lichenoides. It forms red, scaly nodules on the skin and can turn out to be chronic. Often it appears after an infection and turns out to be harmless. However, it can also occur acutely, with a violent attack and cause fever. In this case, the skin rash usually burns and can sometimes develop painful ulcers.

Other infections of the skin

Other rash infections can be caused by fungi, bacteria, parasites and viruses. Others are hives, seborrhoeic eczema, acne, or skin tumors.


Some variants of the so-called tinea (tinea corporis, tinea superficialis) can lead to inflammation and skin rash, for example on the upper body and arms. The pathogens are filamentous fungi.

Yeast fungi (medical Candida) do not automatically lead to diseases. In healthy people, they colonize the mouth, the external sex organs and the gastrointestinal tract. However, if the immune system is disturbed, they can multiply on the skin and mucous membranes and lead to skin rashes and inflammations. Candida fungi are also responsible for diaper dermatitis in infants. In the humid, warm and hardly air-permeable environment of a diaper they spread quickly and can irritate the skin.

Fungal infections often develop in skin folds where moisture forms, even in overweight adults. Skin rash due to yeast fungi can be seen in scaly, colour-changed spots, which spread evenly as in pityriasis versicolor.


streptococcus bacteria penetrate the skin tissue via injuries. There they are able to trigger inflammations with a red, swollen skin rash. These symptoms of erysipelas appear on the face, legs and feet. In addition, there are often complaints such as fever, headaches and chills. A rose must be treated immediately as it can cause complications such as blood poisoning or acute phlebitis.


Parasites also cause skin rash. Scabies, for example, are caused by mites that settle under the skin and cause extremely itchy and allergic exanthema. Other parasites such as head lice, felt lice and clothes lice produce rash-like spots in the areas of the chest, armpit and pubic hair with simultaneous itching.


cell warts (Mollusca contagiosa) are caused by viruses. This infectious disease occurs particularly frequently in tropical regions and leads to inflammatory growths which can spread abruptly. The main areas affected are the face, eyelids, neck, armpits, upper body and genital area.


For the outbreak of urticaria, certain stimuli such as heat, cold, pressure, but also stress factors and allergic reactions can play a role. A skin rash then develops with severely itchy wheals, sometimes accompanied by swelling (angioedema).

Seborrhoeic Eczema

This disease causes reddish spots on the hairline and face with yellowish, greasy dandruff. Men and infants are particularly affected. The skin rash can spread further from the head and face. The cause is still unknown. However, there is some evidence to suggest that overactivity of the sebaceous glands and other factors are responsible. Details on seborrhoeic eczema can be found here.


Akne is the most common skin disease. In its severe forms it can spread suddenly. The typical pimples, nodules and pus-filled pustules appear mainly in the face. However, they can also appear on the back and chest, on the shoulders and upper arms, and on other parts of the body.

skin tumors

Skin tumors of the melanoma and basalioma type usually manifest themselves through locally limited skin changes. In exceptional cases, tumors such as Kaposi’s sarcoma and Paget’s tumor also form skin rashes. It manifests itself characteristically in tongue-shaped surfaces and plates in the genital and anus region as well as in the armpits. Sometimes this leads to pain and increased itching.

5. Autoimmune diseases

Autoimmune diseases of the skin

In autoimmune diseases of the skin, the body defends itself against its own skin cells. In a pemphigoid and other pemphigus diseases, for example, blisters, crusts and other tissue damage form. These appear due to inflammatory processes on the skin surface.

Pemphigoids may occur in rare cases during pregnancy. However, they are more common in older people, for example in combination with other autoimmune diseases or psychological and neurological disorders. Typical for skin rashes are red nodules, followed by itchy blisters filled with fluid. They usually appear on the neck and under the armpits, on the upper arms and thighs and in the umbilical region.

The most common disease in this group is Pemphigus vulgaris. Here the skin rash mainly affects the mucous membrane in the mouth. However, blisters and damage to the skin can also occur on the whole body.

Dermatitis herpetiformis also belongs to this group and may be associated with other autoimmune diseases such as coeliac disease.

Collagenosis and other systemic diseases

Collagenoses are autoimmune diseases of the connective tissue. Their symptoms mainly affect the skin, but also other organs and their vessels. Lupus erythematosus, for example, shows a butterfly-shaped, red skin rash on the face, accompanied by scaly areas on hands and other parts of the body.

Sarcoidosis is an inflammatory systemic disease. It manifests itself in red, painful tissue nodules in the skin, for example on the legs, and in other organs.

Behçet’s disease is also a systemic disease. Its cause is still unknown. Vascular inflammations, pustules and other changes of the skin spread over the whole body develop. The latter mainly appear as aphthae in the mouth, sometimes also on the genitals. Accompanying symptoms are often fever, muscle pain, inflammatory swelling of the joints and fatigue.

The skin rash of the so-called Sweet syndrome is characterized by nodes and thickenings filled with fluid. They appear on the inside of the arms and legs, in the face, on the neck and in the neck. They are accompanied by joint pain and fever. Rheumatoid arthritis, a chronic inflammatory bowel disease and cancer types such as lymphomas and leukaemias are also among the complaints. The cause of Sweet Syndrome, which mainly affects women, is still unknown.

Vascular inflammation

In vascular inflammations autoimmunological processes also play a role. These include the purpura Schoenlein-Henoch. It occurs mainly in small children and is associated with a characteristic skin rash. This manifests itself in bleeding into the skin, which can spread from the legs up to the buttocks. In addition, there are joint complaints and other symptoms.

The purpura pigmentosa progressiva also manifests itself in a skin rash with bleeding. Inflammations and other disturbances of the vessels are possible triggers. The actual cause is unknown. However, it is assumed that delayed allergic reactions to food or medication can be responsible. The rashes start at the legs and can spread from there via the buttocks to the upper body and the arms. They manifest themselves in scaly and itchy skin areas.

Kawasaki’s syndrome is a rare vascular inflammation that usually occurs in children under the age of five. First signs are a high fever, redness in the mouth region and conjunctivitis. Finally, there is a skin rash with redness on the palms of the hands and soles of the feet. The skin on the fingers begins to flake and the lymph nodes swell significantly.

After all, a skin rash can also develop in chronic inflammatory bowel diseases such as Crohn’s disease. This is where autoimmunological processes and other factors come into play, which also cause abdominal pain and diarrhoea.

6. skin rash due to hereditary predisposition

Rider Disease

One of the hereditary diseases that manifest themselves among other things in skin rashes is Reiter’s disease, also known as reactive arthritis. It develops, for example, after gastrointestinal infections or infections of the genitals and urinary tract caused by chlamydia.

Rider’s disease leads to inflammation of the knee and ankle joints, ureter and eyes. The accompanying skin rash appears on the mucous membrane of the mouth, palms and soles of the feet, but can also appear on the whole body. In men, the sexual organs are often still affected.

Familiar Mediterranean Fever

Family Mediterranean fever is one of the fever diseases that are not caused by pathogens but by a hereditary predisposition. The immune system becomes active again and again through certain changes in the genes. The disease relapses are usually accompanied by a skin rash.


Porphyria are rare, usually congenital diseases of the metabolism. However, they can also occur in connection with hepatitis C, for example. People who suffer from certain forms are extremely sensitive to light. Porphyria cutanea tarda causes reddish, itchy areas, blisters and ulcers on the skin. This is especially true for hands, arms and face, which are particularly exposed to light. As the disease progresses, the skin hardens and tightens in the affected regions.

Skin rash – diagnosis

The diagnosis of skin rash is usually made in several steps. First, the doctor obtains information about the patient’s medical history in a detailed conversation with the patient (the so-called anamnesis).

Related to the rash, it is important for the doctor to get answers to the following questions. The information is also useful for an online check on our home page:

  • When and where did it occur for the first time?
  • What did it look like in the beginning?
  • Has the rash spread and changed?
  • Is it shown intermittently, for example under certain environmental influences such as heat or cold?
  • Is the rash causing itching?
  • Had the patient often had skin problems?
  • Has the partner, family member or other close person also a rash?
  • What is the patient’s profession and what do his living conditions look like?
  • Are certain drugs currently being taken?
  • Was the diet changed?
  • If the patient is wearing new clothes?
  • does he use other care products and hygiene articles than usual?

After the doctor has gained a first impression in this way, a physical examination is carried out. In particular, the skin rash and the skin changes are examined. Wooden or plastic spatulas can be used as an aid. With stroking movements of the spatula or pressure, the doctor checks the skin for its reactions. He also measures the size of the affected skin areas. If fungal infections are suspected, the doctor takes a smear of the diseased skin tissue and has it checked by a laboratory.

It is also important for the diagnosis of a skin rash that it is not a tumour. With an incident light microscope the doctor can control the skin changes more precisely. If this is not sufficient, an ultrasound examination is often performed, for example in the case of unclear swelling. An examination of tissue samples provides final certainty.

Skin rash – therapy options

As diverse as the types and causes of skin rash are the corresponding treatment methods. If there is an infection, the therapy depends on the type of pathogen. In the case of a bacterial infection such as scarlet fever, for example, an antibiotic can be prescribed. If it is a virus infection in children, antibiotics are only prescribed if additional complications from bacteria threaten.

Often, however, the sole aim is to alleviate the symptoms of the rash, such as the accompanying itching. Here, antihistamines in the form of ointments or tablets can be helpful.

So-called virustatics are prescribed for diseases such as shingles, which are caused by resurgent herpes pathogens. Virustatics can prevent the further multiplication of viruses.

Medicines against fungi, viruses and antibiotics are not only available for ingestion, but also as creams and ointments, which are applied directly to the affected skin areas. The same applies to cortisone, the most important drug against numerous allergies, skin and autoimmune diseases.

As a rule, the physician prescribes the appropriate active ingredient specifically for either external or internal use. In some cases, drugs that suppress the immune system (immunosuppressants) are also necessary. They are used to treat autoimmune diseases or severe symptoms of psioriasis.

In principle, it can be said that the local therapy of diseased skin areas is in the foreground and therefore drugs for external application predominate. In addition to creams and ointments, tinctures, bath additives and dressings containing active ingredients are also available. The latter may contain substances such as tar, iodine, sulphur or urea. Immunomodulators in the form of ointments are also helpful. They have a positive influence on the immune system in inflammatory diseases such as neurodermatitis.

Many skin diseases and their typical rashes can be treated very well with light therapies. UV radiation helps, for example, with psioriasis, neurodermatitis, pityriasis lichenoides, scleroderma and lichen ruber.

Providing relief for patients with neurodermatitis and psioriasis by staying in certain climatic zones such as the high mountains or by the sea, as far as possible.

Skin rash – preventive measures for a healthy skin

Many diseases can be prevented by appropriate measures. This also applies to skin diseases and skin rashes. With a few simple measures the skin can be protected from negative external influences.

  • The first step is a reasonable body hygiene and care of the skin. The emphasis is on “sensible” because excessive hygiene can be as harmful as constant neglect.
  • The skin should never get too dry.
  • Overly frequent and intensive exposure to sunlight should be avoided wherever possible. Solarium visits can also be harmful.
  • The skin should get plenty of fresh air to breathe.
  • Densely closed skin areas in tight clothing and shoes become slightly moist and sore through perspiration, as pathogens such as fungi find an ideal breeding ground here.
  • Exactly like excessive heat, biting cold should also be avoided. In frosty weather, the skin should therefore be well protected by warm, comfortable clothing.
  • Wear protective clothing against aggressive substances, irritants and harmful substances. Certain fragrances and additives in care products and cosmetics may also cause skin rash.

Diseases of the skin are often caused by external influences, infections or personal predisposition. The best protection against pathogens is a strong immune system. This can be supported by a healthy lifestyle. A balanced diet, lots of exercise and fresh air are good for the body and therefore for the skin. However, since stress can also have an unfavourable effect on the condition of the skin, sufficient and regular relaxation phases should also be observed in order to strengthen the psyche and mental defences. The skin will thank you.
