Eczema causes red, inflamed skin that is usually extremely itchy.
Psoriasis usually causes well-defined patches of redness and the skin is thicker and more inflamed than with eczema, with more of a burning sensation than just an itch.
Eczema usually appears on parts of the body that bend, like the inner elbow, behind the knees, wrists, ankles or on your neck.
Psoriasis often shows up on the palms of your hands, your elbows, knees, scalp, face, lower back or on the soles of the feet.
