Psoriasis is a disorder in which skin grows and replaces itself too rapidly, causing a buildup of red, thickened areas with silvery scales. These scales flake off easily and often, causing the red areas to grow larger still — and the cycle continues. See photos of what psoriasis looks like on the skin. The National Institutes of Health estimates that between 5 and 7.5 million people in the U.S. have psoriasis.
Psoriasis usually develops in adults on the scalp, elbows, knees and lower back — and often appears in the same place on both sides of the body. It may affect quality of life since it can be a painful, itchy and sometimes unattractive skin condition in its moderate to severe forms.
Some people find that infections, stress, dry weather, and some medications (such as lithium or beta blockers) can make their psoriasis worse.
Psoriasis can often be effectively controlled with topical steroid treatment such as that found in Clobex®. Some patients find that light therapy, also called phototherapy, or medicines taken by mouth or injection (systemic treatment) may help improve their symptoms.

Eczema
Eczema, also known as atopic dermatitis, describes a variety of common skin diseases. It is an itchy, red, flaking, weeping, oozing skin condition. Other names for eczema include: skin contact allergy, seborrheic eczema, dry skin eczema (winter itch) or poison ivy. Dermatologists may prescribe topical steroids for eczema.

Other Skin Conditions
Psoriasis and eczema are not the only dermatological conditions that are treated with topical corticosteroids. The term steroid-responsive dermatoses describes a group of skin disorders that improve with treatment of topical steroids.
