What Cream Works For Psoriasis?

Psoriasis is a skin condition that causes cells to produce at an accelerated rate. The condition causes thick, scaly and red or silvery lesions to form. These lesions can be itchy and irritating. Two types of cream--steroid and nonsteroid--are commonly used to treat psoriasis. Nonsteroid topical creams can be bought over the counter in drugstores, but a prescription is necessary for steroid creams.

How Steroid Creams Work

Steroid creams--also called topical corticosteroids--are applied directly to the affected area. These creams minimize inflammation. One of four strengths may be prescribed, based on the severity of the inflammation and its location.

Benefits of Steroid Creams

Steroid creams reduce the swelling and irritation of psoriasis, which can be unsightly and embarrassing. Steroid creams are easily used at home and are sometimes combined with topical antibiotics or antibacterial agents to relieve any infection. They may also be combined with nonsteroid creams.

Dangers of Steroid Creams

Steroid creams should only be used as prescribed. The American Osteopathic College of Dermatology advises that overuse can cause the skin to thin and become resistant to treatment, resulting in a worsening of the condition. In some cases it can lead to internal side effects. The National Psoriasis Foundation also warns that overuse can lead to increased bruising, pigment changes and stretch marks.

Nonsteroid Creams

Nonsteroid creams are topical moisturizers and emollients that are available over the counter in pharmacies. They are sometimes used in conjunction with the steroid creams to relieve itching and soothe the skin. A study published in August 2008 in the journal "Clinics in Dermatology" showed that moisturizing and emollient topical creams can be essential in the treatment of psoriasis. The study found that using these in conjunction with other treatments reduced scaling dramatically.

How Nonsteroid Creams Are Used

Nonsteroid creams are rubbed and absorbed into the skin affected by psoriasis. Unlike steroid creams, they can be used as frequently as the sufferer deems necessary to soften, soothe and moisturize the skin. Topical creams are often most effective when applied after a shower or bath. The creams can capture the moisture when applied while the user's skin is still wet.
