Psoriasis vs Eczema: How to Tell the Difference

Many people confuse psoriasis and eczema because both can cause red, itchy, inflamed skin. However, they are different conditions with different causes and treatment approaches. A correct diagnosis by a dermatologist is essential to achieve long-term control and avoid worsening of symptoms. (Medical News Today)


What is Psoriasis?

Psoriasis is a chronic immune-mediated skin disease in which the immune system speeds up skin cell production. Instead of renewing every 3–4 weeks, skin cells build up within days, forming thick, scaly plaques. It is not contagious. (AAD)

Common Symptoms

  • Thick, raised red plaques
  • Silvery-white scales
  • Mild to moderate itching
  • Burning sensation
  • Cracked skin that may bleed
  • Nail changes (pitting or thickening)
  • Joint pain in some patients (psoriatic arthritis)

What is Eczema?

Eczema (most commonly atopic dermatitis) is a condition in which the skin barrier becomes weak, making the skin dry, itchy, and sensitive to irritants and allergens. It often begins during childhood but can occur at any age. (Medical News Today)

Common Symptoms

  • Intense itching
  • Dry, rough skin
  • Red or inflamed patches
  • Small bumps or blisters
  • Oozing or crusting during flare-ups
  • Thickened skin from repeated scratching
