The affected skin can be red and dry with both.

Usually, you experience repeated episodes of these symptoms over time, which are called flares.

It can be hard for the untrained eye to tell eczema and psoriasis apart because they can look alike.

In fact, eczema and psoriasis are commonly misdiagnosed as each other in babies and kids.

However, a skin specialist (dermatologist) can easily see the differences between the conditions.

While eczema can also occur in these areas, its usually not as severe as it is with psoriasis.
