Psoriasis Laser Treatment

Psoriasis is a chronic, inflammatory skin disease that affects 2 percent of the general population, according to Dr. David Rakel, editor of the text "Integrative Medicine." Psoriasis sufferers develop red, scaly patches in response to overactive skin cell production. Laser treatment remains one available treatment method.

Significance

According to the PsoriasisNet website, laser treatment, also referred to as targeted phototherapy, treats psoriasis by emitting a strong dose of light to the affected skin, sparing healthy skin around it. Laser effectively treats resistant psoriasis patches on the hands, feet and scalp.

Prevention

Laser treatments are relatively new, so there is limited research available on length of remissions. As of September 2010, PsoriasisNet claims that studies show remission lasting from three months to more than one year.

Side Effects

Whether pulsed dye or excimer laser therapy is used, some side effects exist. Bruising occurs with pulsed dye treatments, and both can cause temporary bruising, swelling, redness and burning after treatments, according to PsoriasisNet.

Frequency

The number of laser treatments will vary. According to the Psoriasis Foundation, patients usually receive excimer laser treatments two times a week, with duration dependent on the severity of the disease. Pulsed dye treatments usually occur every three weeks for 15- to 30-minute sessions.
