frequently asked questions


Our mission is to use advanced phototherapy to lessen or eliminate the symptoms of chronic skin conditions and improve the quality of life for those suffering from psoriasis, vitiligo, eczema and other autoimmune skin disorders. We believe the best results are attained through in-office treatments delivered by trained phototherapists using the most advanced FDA-approved equipment.

We treat frustrating symptoms of skin conditions with light therapy, so you can live brighter.

Phototherapy is the use of specific segments of the ultraviolet light spectrum to treat psoriasis, vitiligo, eczema and other autoimmune skin disorders. A targeted narrowband UVB laser is used for targeted spot treatment of affected skin — including face, scalp and groin areas. Light booths are used for patients requiring less-targeted, full-body treatment. Exposure to this specialized light reduces or eliminates the symptoms of chronic skin disorders.

Phototherapy treatments are fast and painless. Affected skin is simply exposed to narrowband UVB light from a light booth or excimer laser. A succession of phototherapy treatments spread over a period of several weeks or months is typical.
 Knowing that a long-term phototherapy program can be time-consuming, Array is committed to getting you in, treated and on your way as quickly as possible. By offering convenient locations, easy parking, Saturday appointments, and a singular focus on chronic skin conditions, Array provides maximum therapy with minimum hassle.

It depends on your diagnosis and the severity of the condition. Array will work with your healthcare provider to customize a treatment plan that will give you the best results possible. For psoriasis, most patients experience improvement in their plaques within 10-15 treatments. Some patients will improve sooner than this and some patients will take a little longer, depending on the severity of their condition and other factors. For vitiligo, some patients may see signs of new pigment within 10 treatments. However, most patients will see signs of new pigment within 20-30 treatments. The amount of time it takes to repigment depends on the location of vitiligo, surface area and individual patient response to treatment.

In general, phototherapy is for patients of all ages who suffer from applicable skin conditions.

Phototherapy is effective in treating the symptoms of psoriasis, vitiligo, eczema and other autoimmune skin disorders. However, these skin disorders are chronic, genetic diseases and flare-ups tend to occur periodically throughout life. As with any treatment method, how long the clearing of symptoms will last after treatment varies from patient to patient.

Phototherapy is safe, especially when compared to other alternatives. At Array, we only provide narrowband UVB phototherapy, which is safer than both sun exposure and UVA light. Ask the experts at Array for more information regarding UVB phototherapy.

Home phototherapy may be appealing to a patient at first, but the upkeep of the equipment (cleaning, storage, calibration), cumbersome treatment delivery, and potential slower treatment response may affect compliance and results, leaving the patient feeling frustrated. Home phototherapy units can be expensive. Sometimes insurance coverage for these units is an issue. You may spend a lot of money on the equipment and not see the results you expected. Large home phototherapy panels are often slow, cumbersome, and consume space in your home. Some hand-held home devices are simply LED lamps which cannot match the speed and effectiveness of lasers used in Array clinics. For patients with hard-to-reach problem areas such as back or scalp, self-administered phototherapy is simply not an option. Dosing for home phototherapy may be challenging. Depending on what area of the body you are treating, you may need to adjust your dose. Keeping track of all the areas you have treated and what times and days you have treated could be problematic. Array administers phototherapy in a clinical setting using the most advanced, FDA-approved equipment available. Each unit is cleaned and calibrated regularly to ensure accurate, safe dosing. Treatments are performed by registered nurses who provide expert, compassionate care. Patients are efficiently treated and monitored, promoting the best possible result. Array patients report being extremely satisfied with their treatment experience.

The term “biologics” describes prescription psoriasis medications such as Humira, Stelara, Enbrel, Cosentyx, and Taltz. Most of these drugs are injectables and have potential side effects including upper respiratory infections and injection site reactions. Phototherapy has very minimal side effects compared to biologic drugs. Phototherapy is safe enough for pregnant women and children, and may be used in combination with biologics if needed for optimal clearance.
