Difference Between Eczema and Psoriasis

Eczema Vs Psoriasis

Eczema Vs Psoriasis: Eczema and psoriasis are both chronic skin conditions that create red, itchy, and inflamed areas, but there are some significant distinctions. Eczema, sometimes called atopic dermatitis, is more common in youngsters and is frequently caused by allergens or irritants. It usually occurs on the inner elbows, knees, and face, and the rash may be weepy or crusty. Psoriasis, on the other hand, is an autoimmune condition in which skin cells proliferate too quickly, resulting in thick, scaly plaques. It is more frequent in adults and often affects the elbows, knees, scalp, and lower back. Psoriasis plaques are drier and less irritating than eczema patches.


  • Dry, itchy areas of red, inflamed skin, frequently seeping or crusting. In adults, it may develop in the creases of the elbows, knees, or behind the ears, whereas in youngsters it may show on the cheekbones or scalp.
  • Complex and poorly understood, but most likely a mix of genetics and environmental factors such as dry skin, allergies, or irritants.
  • Severe itching, particularly at night, which can lead to scratching and aggravation of the disease.
  • Treatment focuses on moisturising, reducing inflammation, and avoiding triggers. Topical steroids, emollients, and lifestyle modifications may be required.


  • Thick, crimson plaques coated with silvery scales, commonly found on elbows, knees, scalp, or lower back.
  • Autoimmune condition in which skin cells multiply too fast. Genetics and certain triggers, such as stress or illnesses, may have a role.
  • Itching may occur, although it is often less severe than eczema. Some kinds of psoriasis may produce burning or stinging instead.
  • Designed to limit skin cell proliferation and minimise inflammation. Topical medicines, light treatment, or systemic drugs may be used in extreme situations.

Difference Between Eczema and Psoriasis

Eczema and psoriasis are both chronic skin disorders that can cause discomfort and reduce quality of life. While they share certain similarities, there are evident differences between the two.




1. Appearance of Lesions

Red, inflamed skin with oozing, crusting, scaling

Thick, silvery scales on red, inflamed skin, with well-defined borders

2. Age of Onset

Often starts in childhood, may improve with age

More likely to begin in adulthood, can occur at any age

3. Affected Areas

Flexural areas (inner elbows, behind knees), face

Extensor surfaces (elbows, knees), scalp

4. Itching Intensity

Intense itching

Itchy, but may not be as severe as in eczema

5. Lesion Shape

Irregular shapes, may vary

Symmetrical, more uniform appearance

6. Triggers

Allergens, irritants, stress

Infections, injuries, stress

7. Inflammatory Mechanism

Overactive immune response

Accelerated skin cell turnover, immune dysfunction

8. Family History

Associated with atopic conditions (asthma, hay fever)

Genetic component, family history of psoriasis more common

9. Distribution of Rash

Can be widespread, affect large areas

Lesions often localized to specific areas

10. Response to Treatment

Responds well to moisturizers, corticosteroid creams

Requires different treatments, including topical, phototherapy, systemic medications

What is Eczema?

Eczema is an inflammatory skin disorder that most commonly affects children but can also develop in adults. It is caused by a mix of hereditary and environmental factors, including dry skin, allergies, and stress. Eczema often manifests as red, itchy skin areas that may leak or crust. These patches are frequently found in the creases of the elbows and knees, on the cheeks, and on the hands.

Key Features of Eczema:

  • Eczema usually appears as red, itchy, and inflamed areas of skin. It may leak or weep in extreme situations. The rash can develop on many body areas, most often in the creases of the elbows and knees in adults and on the cheeks and scalp in toddlers.
  • Eczema's specific aetiology is unclear, however it is most likely caused by a mix of genetics and environmental factors such as allergies, irritants, or stress. It is not infectious.
  • The most common symptom is itching, followed by dryness, flaking, crusting, and burning sensations.
  • Treatment focuses on symptom management and avoiding flare-ups. This can include moisturisers, topical steroids, antihistamines, and, in certain situations, phototherapy.

Causes of Eczema:

  • Genetics: A family history of eczema increases the risk.
  • Immune system overactivity: An overactive immune system triggers inflammation in the skin.
  • Environmental triggers: Dry weather, harsh soaps, dust mites, and certain foods can worsen eczema.

Symptoms of Eczema:

  • Itching: The most common symptom, often intense and scratchy.
  • Dry, scaly, or cracked skin: May appear red, inflamed, or blistered.
  • Oozing or crusting: In severe cases, the affected area may weep or develop crusts.
  • Patchy rash: Typically appears on the inner folds of elbows and knees, hands, face, and neck in adults; cheeks and scalp in children.

What is Psoriasis?

Psoriasis is an autoimmune condition that causes skin cells to develop abnormally fast. This fast development causes the production of thick, red, scaly regions known as plaques. Psoriasis can affect any area of the body, however it is most typically found on the elbows, knees, scalp, and lower back.

Key Features of Psoriasis:

  • Psoriasis manifests as thick, elevated red patches coated with silvery-white scales. It often affects the elbows, knees, scalp, and lower back, but can affect any region of the body, including nails and joints.
  • Psoriasis is an autoimmune disease in which the immune system destroys healthy skin cells, causing them to develop rapidly and accumulate. Genetics and environmental factors may also have a role.
  • While itching is less severe than in eczema, scaling, burning, and joint discomfort are typical. Pitting, discolouration, and thickness are all possible symptoms of nail involvement.
  • Treatment is intended to limit skin cell proliferation and lessen inflammation. Topical creams, gels, light treatment, and systemic medicines are all options in severe instances.

Causes of Psoriasis:

  • Immune system malfunction: T cells attack healthy skin cells, leading to rapid growth and buildup.
  • Genetics: Family history plays a role in susceptibility.
  • Triggers: Stress, injury, certain medications, infections, and cold weather can exacerbate psoriasis.

Symptoms of Psoriasis:

  • Thick, red, scaly patches: Often raised and well-defined, covered with silvery-white scales.
  • Itching: May be present, but usually less intense than with eczema.
  • Joint pain and stiffness: In some cases, psoriasis can affect joints, leading to psoriatic arthritis.
  • Nail changes: Pitting, discoloration, and thickening of nails may occur.

What is the primary difference between Eczema and Psoriasis?

Eczema and Psoriasis are distinct skin conditions. Eczema is characterized by red, inflamed, and itchy skin, often triggered by allergens. Psoriasis, on the other hand, results from an overactive immune system, causing rapid skin cell turnover and the development of thick, scaly patches.

Are there any similarities in the symptoms of Eczema and Psoriasis?

Yes, both conditions can lead to redness, itching, and discomfort. Additionally, they may share similarities in appearance, making it crucial to consult a dermatologist for an accurate diagnosis.

Can Eczema and Psoriasis be triggered by similar factors?

While both conditions can be influenced by genetic factors, stress, and environmental triggers, the specific triggers may differ. Eczema is often associated with allergies, while Psoriasis can be exacerbated by stress and infections.

How do the rashes differ between Eczema and Psoriasis?

Eczema rashes are typically red, inflamed, and may present as blisters. Psoriasis, on the other hand, leads to thicker, silver-white scales on raised, reddish patches.

Are there any distinct features in the affected areas for Eczema and Psoriasis?

Yes, Eczema commonly affects the folds of the skin, like the inner elbows and behind the knees. Psoriasis, however, often appears on the scalp, knees, elbows, and lower back.

Can Eczema and Psoriasis be cured, or are they lifelong conditions?

While there is no permanent cure for either condition, both Eczema and Psoriasis can be managed effectively with proper treatment and lifestyle adjustments.
