Eczema and psoriasis are two chronic skin conditions that present similarly, with rashy, discolored skin and itching or burning sensations. Despite these similarities, these conditions are different and require specific treatments to minimize symptoms. Turn to the Berman Skin Institute to identify your condition and help you manage your symptoms.
Eczema
Eczema, also called atopic dermatitis in its most common form, is usually caused by environmental and genetic factors. This condition occurs when the skin barrier is impaired by pollutants and irritants, which may be from the local climate or the air quality in a person’s home. People with a family history are more likely to develop eczema themselves. Eczema is characterized by itchy, red and inflamed dry patches that often develop in skin folds, like the inner elbows and the backs of knees.
Psoriasis
Psoriasis is an autoimmune disease caused by rapid skin cell turnover. Skin cells grow faster than usual, leading to thick patches of skin in various areas. While experts still don’t fully understand what causes psoriasis, factors like stress, infections or medications like prednisone may trigger the condition. While psoriasis can also appear as red or purple patches on the skin, it also comes with thick, silvery or white scales.
Psoriasis can affect any part of the body, but common areas include the elbows, knees and scalp.
Eczema vs. Psoriasis: Key Distinguishing Features
The key features that separate these conditions are:
- Appearance: Psoriasis is a thicker patch of dry skin that can grow scaly. Typically, psoriasis patches have a very clear border between affected and unaffected skin. Eczema is much thinner and often lacks those defined borders.
- Location: While both conditions can occur anywhere, eczema typically occurs in skin folds. Psoriasis also commonly occurs in these areas, but it’s also more likely to appear on the scalp, back and soles of the feet, where eczema is less likely to appear.
- Cause: Eczema is a reaction to irritants, and psoriasis is due to overactive skin cells. Ultimately, both conditions are caused by reactions of the immune system, but they involve different parts of it. Eczema is an active inflammation to fight an allergy, while psoriasis activates the branch of the immune system that fights bacterial and fungal infections.
Diagnosis, Treatment and Living With Psoriasis or Eczema
When it comes to how doctors diagnose psoriasis versus eczema, the process is relatively the same. A dermatologist will ask you about your symptoms and examine the affected areas, paying close attention to the skin’s texture.
While there is no cure for these conditions, your dermatologist can recommend a range of treatments to ease symptoms. These treatments usually include a series of topical steroids, moisturizers and prescription medications.
Both of these conditions tend to flare up and subside over the course of your life. Working with a dermatologist during those flare-ups can help you manage symptoms safely and improve your quality of life.
