If you're living with psoriasis, you know how uncomfortable and embarrassing the red, itchy, scaly skin can be. Treatment options for psoriasis include steroid cream or other medicated creams, oral medications, and light therapy.

All of these treatments work well, but medications can have side effects and light therapy requires a regimen of three sessions a week for two to three months followed by maintenance therapy.

Today, there is another option for treating psoriasis: excimer lasers. Excimer lasers aim a high intensity ultraviolet B (UVB) light dose of a very specific wavelength -- 308 nanometers -- directly at the psoriasis plaques. Because the laser light spares the surrounding skin, it reduces the risk of UV radiation exposure. Excimer lasers are used to treat mild-to-moderate psoriasis.

Excimer laser treatments are performed at Alpha Dermatology. Each session takes only a few minutes. During the treatment, the provider aims the laser directly at patches of psoriasis. You might feel some warmth at the site or a snapping sensation against the skin.

With excimer laser therapy, patients usually have 2 sessions a week for 4 to 10 sessions to get results.

Your doctor will determine your dose of laser light based on the thickness of your psoriasis plaques and your skin color (a lower dose is used on lighter skin). During the procedure, you will be given dark goggles to protect your eyes.
