Phototherapy can be used alone or with medicines. UVB light therapy is used alone to treat severe psoriasis. Typically, when medicines for psoriasis are used with light therapy, you will use or take the medicine first. You may apply it to your skin, take it by mouth, or use it as bath salts in water. Then you will go into a booth and be exposed to the UV light. Using two kinds of treatment is called combination therapy. Three common combination therapies are:

Psoralen and UVA light therapy (PUVA), which combines UVA exposure and a medicine (called a psoralen) that makes your skin more sensitive to light.
The Ingram regimen, which combines anthralin, tar products, and UVB phototherapy.
The Goeckerman treatment, a combination of tar products and UVB phototherapy.

Your body is exposed to UV light from banks of light tubes that give off either UVB or UVA light in a booth. Booths come in several designs. Some look like phone booths and you can stand in them. Others look like tanning beds and you can lie down during treatment. The booth will record the total amount of light you are exposed to.

In general, your entire body is exposed to the light. (If psoriasis affects only certain areas of your body, UV light may be directed at these selected areas only.) You will wear sunglasses that block UV light and goggles or a blindfold to protect your eyes from getting cataracts. Men may also need to shield their genitals to protect them from an increased risk of genital cancer.
