Excimer Laser


Using a carefully focused beam of laser light delivered through a sophisticated liquid light guide delivery system, the excimer laser system is designed to clear unsightly psoriatic skin plaques quickly and effectively. Because it concentrates light on active lesions, the excimer laser allows your health care technician to deliver the high therapeutic doses necessary for rapid clearing without risk to healthy skin.

What is the Excimer Laser?

Excimer uses a focused beam of light at a wavelength of 308 nm.  This targeted wavelength has been shown to be particularly effective in treating psoriatic plaques and vitiligo. The ray of light is delivered via a hand held wand that focuses on the lesion rather than treating your entire body like narrowband UVB phototherapy.  The advantages include faster clearance of lesions because a higher dose can be delivered to the specific areas that need it without affecting healthy skin. It can also be used to treat areas that are difficult to treat in a phototherapy unit such as behind the ears and the genitals.

What does the treatment involve?

Patients attend treatments 1-3 times weekly.  The amount of UV delivered is calculated carefully and monitored based on the patient’s skin type, age, skin condition, site of treatment, and prior response to treatment. 

How many treatments will I need?

 The duration of treatment varies depending on the skin condition being treated and the extent of the condition.  Usually some response is noted in 6-8 treatments.  Often, a complete response occurs in 20-30 treatments.
