What is the Difference Between Eczema and Psoriasis?

Eczema and psoriasis are two common skin conditions that can cause inflammation, irritation, and skin discoloration. While they share similarities, there are key differences between the two:

1. Appearance: Eczema is characterized by poorly demarcated red, dry areas with fine scale, while psoriasis appears as red, well-circumscribed lesions (called plaques) with heaped-up, white scaling. Eczema may also cause rough, leathery patches, while psoriasis often presents as silvery and scaly raised patches.
2. Location: Eczema tends to develop in the folds and creases of the skin, such as behind the knees, on the neck, in the creases of the arms, and on the face. Psoriasis typically develops on the outer surface of the skin in areas like the scalp, front of knees, and belly button.
3. Age of onset: Eczema is more common in children and may improve as they get older, while psoriasis tends to be a more lifelong condition. Eczema usually starts in childhood, while psoriasis typically appears between ages 15 and 35, but can also occur at other ages.
4. Itching: Eczema causes intense itching, while psoriasis tends to cause mild itching.
5. Associated conditions: Eczema is often associated with dry, sensitive skin and a family history of eczema, asthma, or hay fever. Psoriasis is linked to other serious health conditions like diabetes, heart disease, or depression.

A dermatologist can often diagnose eczema or psoriasis after an exam and visual assessment, and may order tests to confirm the diagnosis. Treatment can help manage symptoms for both conditions, regardless of the specific diagnosis.
