Psoriasis Topical Treatment

Overview

Itchy, red or silver-colored scales on the skin can be signs of psoriasis. Psoriasis is a skin disease in which skin cells grows faster than normal. When new skin cells accumulate on top of older cells that have not yet been shed, the result is thickened skin that can become scaly, dry and uncomfortable. Mild to moderate psoriasis can be treated with topical creams and ointments. However, all topical treatments for psoriasis should be used under the supervision of a physician.

Step 1

Consult with your doctor to determine what type of topical medication is appropriate for your needs. Psoriasis treatments can contain ingredients, such as tar or salicylic acid, to slow the growth of new skin cells, to induce peeling of the skin, and steroids to reduce inflammation. The severity and location of your lesions will be deciding factors about which topical medication to use.

Step 2

Use a small amount of a topical medication, especially strong steroid drugs, until you know how your skin will react. Some creams and ointments can cause more irritation, even as they soften and lift scales from the skin's surface. Discuss any side effects with your doctor to determine if you should discontinue use.

Step 3

Prepare for use of coal tar-based medications by wearing old clothing or using "retired' bedding. Tar, a common ingredient in psoriasis treatments, relieves inflammation and itching and helps slow the production of new skin cells, according to the National Psoriasis Foundaiton (NPF). But tar-based products are also messy and can discolor clothing upon application.

Step 4

Moisturize skin that is affected by psoriasis in addition to using a topical medication. Salicylic acid and corticosteroid preparations can leave the skin dry and irritated. Use an ointment-based moisturizer after bathing to retain moisture on the skin in between treatments.

Step 5

Increase the effectiveness of the topical agent by following a technique called occlusion, which entails covering the medicated area of skin to allow the medication to work better. Cover the affected area with plastic wrap, a bandage or, if your feet are affected, put on a pair of cotton socks. Occlusion may not be appropriate for everyone, so check with your doctor before practicing this.
