Eczema vs. Psoriasis: How to Tell the Difference

Eczema and psoriasis are two of the most common chronic skin conditions, and because both cause red, itchy, irritated patches, they are easy to confuse. Getting the diagnosis right matters, because the two conditions are treated differently. Here is how a dermatologist tells them apart, and when patients in Flint and Genesee County should come in for an expert opinion.

What does eczema look and feel like?

Eczema, also called atopic dermatitis, tends to be intensely itchy, and the itch often comes before the rash. The skin usually appears dry, inflamed, and sometimes cracked or weepy, and over time it can become thickened from repeated scratching. It commonly shows up in the bends of the elbows and knees, on the hands, and on the face, especially in children, though it can appear anywhere. Eczema frequently runs in families alongside allergies and asthma, part of a pattern doctors call the atopic march, and it flares in response to irritants, allergens, dry air, harsh soaps, and stress. Many people find their symptoms worsen during Michigan winters when indoor heat dries the air.

What does psoriasis look and feel like?

Psoriasis is an autoimmune condition that speeds up the skin cell life cycle, causing cells to build up on the surface faster than they can shed. This creates thick, well-defined plaques covered with silvery scale that may crack or bleed if scratched. Psoriasis more often appears on the outer elbows and knees, the scalp, the lower back, and around the nails. While it can itch, many people describe it as burning or sore rather than intensely itchy. It is also linked to nail changes like pitting, and in some patients joint pain and stiffness from psoriatic arthritis, which is why psoriasis is considered a whole-body inflammatory condition rather than just a skin problem.

What are the key differences at a glance?

A few distinguishing features can help point in the right direction, though only a professional exam confirms the diagnosis.

• Itch: eczema is usually very itchy, psoriasis is more often burning or sore
• Appearance: eczema is dry and inflamed, psoriasis has thick plaques with silvery scale
• Location: eczema favors the inner folds, psoriasis favors the outer surfaces and scalp
• Associations: eczema links to allergies and asthma, psoriasis links to nail changes and joint pain

How are they diagnosed and treated?

A dermatologist can often distinguish the two with a careful skin exam, and occasionally a small biopsy reviewed by a dermatopathologist confirms the diagnosis. Treatment differs: eczema care focuses on repairing the skin barrier with moisturizers, topical anti-inflammatories, and trigger avoidance, while psoriasis may call for topical treatments, light therapy, or systemic and biologic medications that target the immune system. Both conditions are highly manageable with the right plan.
