  • by

Dermatitis is a common term for skin inflammatory conditions. Examples are atopic dermatitis, contact dermatitis, and seborrheic dermatitis. Examples include (dandruff). These conditions lead among other symptoms to red eruptions, dry skin and itchiness. You can manage your dermatitis through your regular medical practitioner or dermatologist.

Dermatitis- Types, Symptoms, Causes, Treatment & Prevention

Types of Dermatitis

Atopic dermatitis (eczema).

The condition that makes your skin red and itchy is atopic dermatitis (eczema). In children, it’s common but can happen at any age. Dermatitis atopic is (chronic) long lasting and tends to erupt on a regular basis. Asthma or hay fever may be associated with it.

Types of Dermatitis
Contact dermatitis.

Contact dermatitis is the type of eczema that occurs when a certain substance is contacted. Eczema is the name for a number of conditions which lead to dryness and irritation of the skin. Contact dermatitis generally improves or eliminates totally if the problem substance is identified and avoided.

Diaper dermatitis (rash).

This type of dermatitis is caused by skin over hydration, maceration, extended urinary and feces contact, retained diaper soaps and topical preparations. In most individuals, signs and symptoms are limited to the diaper covered area.

 type of dermatitis
Dyshidrotic dermatitis.

Dyshidrotic dermatitis is a type of eczema also called pompholyx . Intense itchy blisters develop on the edges of the fingers, the toes, palms and the floors of the feet characterize this skin condition. Acute, recurrent or chronic dyshidrotic dermatitis can affect adults and teens.

Type of eczema

Neurodermatitis is a chronic itching or scaling skin condition. You will notice raised, rough, itchy areas on your skin — usually on your neck, wrists, forearms, legs, or anal area. The condition of neurodermatitis starts with an itchy skin patch. It’s even more scratching.

Chronic itching or scaling skin condition
Nummular dermatitis.

Nummular eczema is a name given for a stubborn rash that shape the coin patches of the skin. The lesions may clear up or scaly in the middle as they get older and then resemble like fungus (ring worm) or psoriasis.

Perioral/Periorificial dermatitis.

Perioral dermatitis is a red rash that flows around your mouth. With swollen, inflamed bumps known as papules, your skin can be scaly, dry and flaky. It is a dermatitis of many types. Perioral dermatitis can look like acne, often confused.

Seborrheic dermatitis (dandruff, cradle cap).

Seborrheic dermatitis (seb-o-REE-ik) is a common condition of your skin, affecting your scalp mainly. This results in skin patches, red skin and stubborn dandruff. The oily body areas, like face, sides of the nose, eyebrows, ears, eyelids and chest, can also be affected by seborrheic dermatitis.

What are the symptoms of Dermatitis?

Dermatitis symptoms range from mild to severe and differ according to the area of the body. Not everyone suffering from dermatitis has all symptoms.

Dermatitis symptoms can usually include:

  • rashes
  • blisters
  • Skin dry, cracked
  • itchy skin
  • Skin painful, stingy or burning
  • redness
  • swelling

How dermatitis occurs

Depending on the type, the causes of skin disease vary. Unknown causes could arise in certain kinds, such as dyshidrotic eczema, neurodermatitis and nummular dermatitis.

Contact dermatitis

Contact dermatitis is a type of skin reaction that occurs when the skin comes into contact with an allergen or an irritant. An irritant causes physical damage to the skin, whereas an allergen causes an immune response that results in a skin reaction. Detergents, soaps, disinfectants, metals such as nickel, cement, fragrances or perfumes, cosmetics, and some plants such as mustard and clematis are all known causes of irritant contact dermatitis.

Metals such as nickel or cobalt, rubber, strong adhesives, some dyes and resins in clothing, and some topical medications such as corticosteroid creams are examples of substances that may cause allergic contact dermatitis.


This condition is caused by irritated nerve endings beneath the skin, resulting in an intensely itchy sensation and an overwhelming desire to scratch. Scratching can eventually cause skin thickening and redness.

Atopic dermatitis

This type of dermatitis, also known as eczema, occurs when the body becomes hypersensitive to certain foods, allergens, or environmental factors. The condition frequently runs in families and can coexist with other atopic conditions like hay fever and asthma. Food allergies can aggravate eczema, and some foods that have been linked to more severe eczema symptoms in children include cow’s milk, wheat, soya, nuts, fish, and eggs.

Seborrheic dermatitis

This condition affects skin with sebaceous glands and most commonly affects the face, nose, and inside of the ears. Other affected skin areas include the back, neck, and chest. When it affects children, the condition is commonly referred to as “cradle cap.”

The cause of seborrheic dermatitis is unknown, but the factors involved include a yeast called malassezia present in the skin’s oily secretions, neurology, stress and fatigue like Parkinson’s.

Statis dermatitis

Stasis dermatitis develops when varicose veins obstruct venous flow from the legs to the heart, causing blood to pool in the lower limbs. The veins then leak blood and fluid into the skin tissue.

Perioral dermatitis

 This is a condition that primarily affects women and is characterized by the development of a rash around the mouth that consists of tiny raised, red bumps. The use of topical steroids, moisturizers, cosmetics, and sunscreen has been linked to the condition.

How dermatitis is diagnosed

Dermatitis is usually diagnosed by your healthcare provider after examining your skin. However, if there is any doubt, they may conduct the following tests:

  • Blood tests to rule out other causes of the rash that aren’t related to dermatitis.
  • A skin biopsy is used to differentiate one type of dermatitis from another.
  • A skin test for allergies.

How dermatitis is treated

Dermatitis treatment varies depending on the cause and severity of your symptoms. Dermatitis treatment may include one or more of the following, in addition to the lifestyle and home remedy recommendations listed below:

  1. Using corticosteroid creams, gels, or ointments on the affected skin
  2. Applying creams or ointments to the affected skin that have an effect on your immune system (calcineurin inhibitors)
  3. exposing the affected area to varying levels of natural or artificial light (phototherapy)
  4. For severe disease, oral corticosteroids (pills) or injectable dupilumab are used.
  5. Wet dressings are a medical treatment for severe atopic dermatitis that requires applying a corticosteroid to the affected area and wrapping it in wet bandages.

How long dermatitis takes to be cured

It will take two to four week to heal dermatitis condition if you get the correct treatments from a professional. The time can be varied according to the type of dermatitis and the procedure of the treatments.


  • Irritants and allergens should be avoided. Identify and avoid substances that irritate or cause an allergic reaction on your skin.
  • Cleanse your skin. If you wash your skin immediately after coming into contact with the rash-causing substance, you may be able to remove the majority of it. Warm water and a mild, fragrance-free soap are recommended. Rinse thoroughly. Wash any clothing or other items that have come into contact with a plant allergen, such as poison ivy, as well.
  • Wear gloves or protective clothing. Face masks, goggles, gloves, and other protective equipment can protect you from irritants such as household cleaners.
  • Cover metal fasteners next to your skin with an iron-on patch. This can help you avoid having an allergic reaction to jean snaps, for example.
  • Use a barrier cream or gel to protect your skin. These products can provide a layer of protection for your skin. An over-the-counter skin cream containing bentoquatam (IvyBlock, for example) may prevent or reduce your skin’s reaction to poison ivy.
  • Apply a moisturizer. Applying moisturizing lotions on a regular basis can help restore your skin’s outermost layer and keep it supple.
  • Take precautions when around pets. Plant allergens, such as poison ivy, can cling to pets and then spread to humans.

Is dermatitis contagious in humans?

Dermatitis does not endanger your health in any way. It is not contagious, nor does it imply that your skin is dirty or infected. There are treatment options and medications available to help you manage your symptoms.

Foods to take

Certain foods can cause the body to release immune system compounds that cause inflammation, which in turn contributes to an eczema flare-up in people with eczema. A diet that is anti-eczema is similar to a diet that is anti-inflammatory.

Foods that are anti-inflammatory include:

Fish is a natural source of omega-3 fatty acids, which can help to reduce inflammation in the body. Salmon, albacore tuna, mackerel, sardines, and herring are examples of omega-3-rich fish.

Probiotic foods, which are bacteria that promote good gut health. Yogurt with live and active cultures, miso soup, and tempeh are a few examples. Probiotics can also be found in fermented foods and beverages such as kefir, kombucha, and sauerkraut.

Foods high in anti-inflammatory flavonoids. Colorful fruits and vegetables such as apples, broccoli, cherries, spinach, and kale are examples.Eating more of these foods and avoiding trigger foods may help to reduce eczema flare-ups.

 Foods to avoid

Symptoms may worsen if you consume inflammatory foods. Inflammation is caused in the body by added artificial sugars, trans fats, processed meat, red meat, refined carbs, and dairy.

Nickel-containing foods Nickel is a known allergen that aggravates the symptoms of dyshidrotic eczema. Dyshidrotic eczema is a type of eczema characterized by the formation of small blisters on the hands and feet. Whole wheat and grains, rye, oats, cocoa, baking powder, soy products, canned foods, and dried fruits all contain nickel.
