Eczema (atopic dermatitis) and psoriasis are two of the most common chronic skin conditions in the United States, and they are frequently confused with each other. While both cause red, inflamed skin, they have important differences.
What Causes Each Condition?
Eczema is primarily driven by a defective skin barrier combined with an overactive immune response. The barrier defect allows moisture to escape and irritants to enter, triggering inflammation.
Psoriasis is an autoimmune condition in which the immune system mistakenly attacks healthy skin cells, causing them to grow too rapidly. This leads to a buildup of cells on the surface.
How Do They Look Different?
| Feature | Eczema | Psoriasis |
|---|---|---|
| Skin appearance | Red, inflamed, oozing or crusting | Thick, silvery scales on raised plaques |
| Color | Pink to red | Deep red with silver/white scales |
| Texture | Weepy, raw | Dry, thick, scaly |
| Common locations | Inside elbows, behind knees, face | Scalp, elbows, knees, lower back |
| Itching | Severe, constant | Moderate, burning or stinging also common |
Who Gets Each Condition?
Eczema typically begins in childhood, though adults can develop it. Psoriasis often first appears between ages 15 and 35.
How Are They Treated?
Both conditions have benefited enormously from recent research. Biologic medications have transformed outcomes for moderate-to-severe disease in both groups.
