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.
