Of all autoimmune diseases, psoriasis is the most common with nearly 7.5 million Americans affected. You are not alone.


Generally, these are the major types of psoriasis you should know about.

PLAQUE is the most common form of psoriasis characterized by raised, inflamed, red lesions covered by silvery white scales. Typically it surfaces on elbows, knees, scalp, and the lower back.

GUTTATE frequently emerges in childhood or young adulthood, appearing as small, red, individual spots on the torso, arms, and legs after a bacterial (strep) infection. Guttate psoriasis often clears on its own without treatment.

INVERSE surfaces as bright-red lesions that are smooth and shiny in the armpits, groin, under the breasts, and in other skin folds around the genitals and the buttocks.

PUSTULAR is an adult disease, characterized by white blisters of noninfectious pus surrounded by red skin. It may be either localized, such as the hands and feet, or generalized, affecting most of the body.

ERYTHRODERMIC is an inflammatory form of psoriasis, characterized by periodic, widespread, fiery redness of the skin and a shedding of the scales in sheets. Typically, it affects most of the body surface.

SCALP PSORIASIS can be mild with slight, fine scaling but it can also be severe with thick plaques covering the entire scalp. The visible signs often extend beyond the hairline onto the forehead, the back of the neck and around the ears. Scalp psoriasis is very common, affecting up to 80% of all psoriasis patients.


While its precise cause is not fully understood, scientists know that the immune system and genes play key roles in its development. Psoriasis is unpredictable. It may be limited to a few lesions or may involve moderate to large areas of skin. When less than 3% of the body is affected by psoriasis, it’s considered mild; 3 to 10% of the body psoriasis is considered moderate; and more than 10% is considered severe.

(For most individuals, the palm of the hand is about the same as 1% of the skin surface.)**

Dermatologists treat the disease based on the severity of its symptoms, the psoriasis type and the patient’s response to treatment. However, the severity of psoriasis can also be measured by how psoriasis affects the quality of life—a factor we know is just as important as any medical concern, even if it just affects a small area.


Psoriasis is a chronic disease with no known cure, but it can be put into prolonged remission with treatments that manage its symptoms and clear its visible signs. With XTRAC you can LIVE FREE and CLEAR of the physical and emotional burdens of psoriasis.

One of the most effective solutions is the XTRAC light treatment, the only FDA-cleared excimer laser clinically proven to slow and reverse the growth of psoriatic cells. The XTRAC excimer laser delivers a highly targeted therapeutic beam of UVB light to areas of skin affected by psoriasis without harming the surrounding skin.

Of patients meeting clinical study protocol requirements
84% reached improvement of 75% or better after 10 or fewer treatments
50% reached improvement of 90% or better after 10 or fewer treatments

“The XTRAC appears to have considerable advantages over other available treatment modalities for psoriasis, including fewer treatments to achieve results, and the added safety of site-specific dosing without exposure to healthy skin. In addition, this study has shown the XTRAC to be well tolerated and effective in treating thick, scaled plaques on the knees and elbows, which are often resistant to treatment.”
