Psoriasis vs Eczema - Comparison Table

Basis	Psoriasis	Eczema
Onset age	Typically begins between 15 and 35 years, though it can occur at any age.	Often starts in infancy or early childhood, with variability.
Lesion appearance	Well-demarcated, raised plaques with silvery scales.	Red, inflamed patches with crusting or oozing in acute flares.
Common sites	Elbows, knees, scalp, and lower back.	Flexural areas such as inner elbows, behind the knees, wrists, and face in infants.
Itching intensity	Itching ranges from mild to moderate.	Often intense and persistent itching.
Nail involvement	Nail pitting, discoloration, and onycholysis.	Nail changes are less common but can occur in severe eczema.
Scalp involvement	Common on the scalp, causing flaking.	Scalp involvement occurs, sometimes with itch.
Family history	Strong genetic predisposition; family history is common.	Often associated with allergic family history.
Triggers	Koebner phenomenon, infections, stress.	Allergens, irritants, weather changes, and skin irritants.
Course pattern	Chronic, relapsing with remission.	Chronic with flares and remissions.
Seasonal variation	May worsen in winter due to dryness.	Dry weather can worsen flares.
Skin barrier function	Immune-driven inflammation; barrier involvement present but not primary barrier defect.	Significant barrier dysfunction with dry skin.
Associated conditions	Psoriatic arthritis; metabolic syndrome risk.	Atopic conditions like asthma and allergic rhinitis.
Diagnostic approach	Primarily clinical; biopsy rarely needed.	Clinical evaluation; patch testing or biopsy if uncertain.

What is Psoriasis?

Psoriasis is a chronic inflammatory skin condition involving immune system activity and genetic factors. It presents as raised, well-defined plaques with silvery scales, most often on the elbows, knees, scalp, and lower back, and is not contagious.

It often follows a relapsing course with periods of flare and remission. Triggers can include infections, stress, skin trauma, and certain medications. Diagnosis relies on clinical examination, with biopsy reserved for uncertain cases. Management guidance should be discussed with a qualified clinician in India.

What is Eczema?

Eczema is a common inflammatory skin condition marked by itchy, red patches that may blister, crust, or scale. It often begins in childhood and is linked to a tendency for allergic diseases, with skin barrier dysfunction playing a central role.

It tends to form in areas where skin flexes or is exposed to irritants and allergens, and flares can be triggered by dry air, soaps, stress, or seasonal changes. Diagnosis is usually clinical; patch testing can help identify triggers, and insurers' guidance may be needed.

Advantages of Eczema
