Question: How Does Phototherapy Work For Psoriasis?

Light therapy is effective for reducing or clearing up the symptoms of psoriasis.

An estimated 75 percent of people using narrow-band ultraviolet B (UVB) therapy, which is the most common type, will develop clear skin.

This will last for at least 6 months.

How long does phototherapy take to work for psoriasis?

“A burn caused by narrow-band UVB can take 24 to 48 hours to come out, so protect your skin in the day or so after phototherapy to avoid adding to any damage,” said Duffin. Get a full-body check from your dermatologist every six months while undergoing phototherapy to monitor skin for cancer.

How much does phototherapy for psoriasis cost?

A tube of topical psoriasis medications might cost between $500 and $600. And biologics, a relatively new class of treatment for psoriasis and psoriatic arthritis, can run $15,000 to $20,000 or more a year.

How effective is light therapy for psoriasis?

Present in natural sunlight, ultraviolet B (UVB) is an effective treatment for psoriasis. It also may be effective with fewer treatments per week than broad-band UVB. During UVB treatment, your psoriasis may worsen temporarily before improving. The skin may redden and itch from exposure to the UVB light.

Can UVB make psoriasis worse?

Keep in mind that UVB treatment may cause the psoriasis to get worse before it gets better. Skin that gets red and itchy is generally a signal that less light is needed. It’s also important to use sunscreen on all areas of skin that aren’t affected by psoriasis.
