Laser Treatment for Psoriasis

What You Should Know Before Starting Laser Treatment

Laser treatment for psoriasis can produce dramatic results in some people -- but this therapy isn't for everyone. To make sure you're a good candidate, have a complete health history and exam done before starting treatment. 

Avoid laser treatments if you have: 

• Lupus
• Sun sensitivity
• Xeroderma pigmentosum (an inherited disease that causes sensitivity to sunlight)
• Risks for, or a history of, skin cancer
• A condition that requires you to take medications that make you sensitive to the sun
• A weakened immune system

Are There Any Risks to Laser Treatments for Psoriasis?

Laser therapy is generally safe, but some people have reported side effects after treatment, including: 

• Temporary redness, itching, burning, and stinging
• Blistering
• Purple-colored spots (purpura) on the skin
• Darkening or lightening of the skin (hyperpigmentation or hypopigmentation)
• Scarring 

More research is needed to determine whether exposure to UVB light from the excimer laser might increase the long-term risk for skin cancer.
