Allergic Dermatitis

Dermatitis comes in a variety of forms. Some may cycle between times of no symptoms and flare-ups, while others may endure for an extended period of time. There are dermatitis forms that are more common in youngsters and others in adults.

• Atopic dermatitis

  This is often known as eczema. Atopic dermatitis often appears in early childhood and can run in familiesTrusted Source. But it can also emerge in later life.

  Atopic dermatitis cannot be cured. Symptoms of the illness usually come on in cycles, with periods of little to nonexistent symptoms in between flare-ups. Skin in certain areas may get dry, rough, and irritating during flare-ups.

• Contact dermatitis

  When a material comes into contact with your skin and reacts negatively, it might lead to contact dermatitis. These responses may progress to blistering, itching, burning, or stinging rashes.

  An allergic or irritating response can lead to contact dermatitis. An external material directly affects the skin and triggers a reaction in irritating contact dermatitis.

  In contrast, an external substance may not really cause skin harm in allergic contact dermatitis, but it will trigger an immune system reaction that will lead to skin damage nonetheless.

• Dyshidrotic dermatitis

  The skin is unable to defend itself when it has dyshidrotic dermatitis. This causes dry, itchy skin that frequently develops tiny blisters. It mostly affects the hands and feet, though it can also happen to anyone who sweat a lot in these areas.

• Seborrheic dermatitis

  When seborrheic dermatitis affects infants, it's sometimes referred to as "cradle cap." Although it can also affect the face, chest, and area around the ears, this kind of dermatitis most frequently affects the scalp.

  Dandruff, scaly areas, and skin discolouration are frequently the results. These symptoms may intensify due to stress or sleep deprivation.

  Although seborrheic dermatitis cannot be cured, it can be successfully managed.

Other types

Some other types of dermatitis include:

• Neurodermatitis

  This kind is marked by an irritated patch of skin that is frequently brought on by stress or other external factors.

• Stasis dermatitis

  This kind involves changes in the skin brought on by inadequate blood flow. In the lower extremities, it might result in skin discolouration and even thickening of the skin's texture.

• Dermatitis neglecta

  Sebum, perspiration, germs, and corneocytes collect in a small area of the skin to form a thick, sticky layer of dirt that causes dermatitis neglecta.

• Nummular dermatitis

  Oval skin lesions are a symptom of nummulular dermatitis, which frequently follows a skin injury. Nummular is short for "coin-like."

Dermatitis can cause mild to severe symptoms, which vary in appearance based on the affected body part. Although it's frequently challenging to differentiate between them, symptoms vary depending on the type of dermatitis causing them.

In general, dermatitis can cause the following symptoms:

• rashes
• blisters
• dry, cracked skin
• itchy skin
• painful skin, with stinging or burning
• swelling

Skin discolouration can also be caused by dermatitis. On various skin tones, this will seem differently.

Dermatitis rashes usually seem gray, purple, or slightly darker than your natural skin tone on those with darker skin. Dermatitis patches usually appear pink or red on lighter skin types.

Acute or chronic dermatitis can have radically diverse appearances despite sharing the same underlying mechanism of development.

• Redness or swelling, papulation, vesiculation, seeping and weeping, and even blistering are all signs of acute dermatitis.
• Skin thickening with emphasis on wrinkles, hyperkeratosis, scaling, fissuring, excoriation, and hyperpigmentation are all signs of chronic eczema.
• Both traits will be present in subacute dermatitis.
