Dermatology Consultants is one of only two dermatology practices in Minnesota offering the innovative new laser for psorasis treatment and vitiligo treatment, the PHAROS EX-308. The “Excimer” laser  works by delivering ultraviolet light to the skin and is indicated for mild to moderate psoriasis treatment.   Patients must first have a consultation with their dermatologist before scheduling laser treatments.


Frequently Asked Questions: 

How does PHAROS EX-308 Excimer Laser work?
The EX-308 Excimer laser creates a concentrated, beam of ultraviolet light that is delivered to lesions through a hand piece that rests directly on the skin. By precisely targeting only active lesions without exposing healthy skin, the laser safely delivers high-dose psoriasis treatment for fast clearing and long remission.

Who is a candidate for treatment?
The laser is ideal for  mild to moderate psoriasis treatment. Traditionally hard-to-treat areas such as knees, elbows, and scalp are easily treated, thanks to the laser’s aiming beam and adjustable spot size hand piece. The targeted high-dose therapy can effectively treat stubborn plaques, even those that have not responded to other treatments.

How does treatment compare with other psoriasis treatments?
Unlike topical creams and gels, treatment with the laser may not require any daily maintenance. Each patient is unique, but some patients enjoy several months of treatment-free remission. Excimer laser treatments are relatively painless and take only a few minutes. Equally important, patients typically need fewer treatments than conventional NBUVB light therapy.

Is treatment safe? 
Due to the targeted nature of laser therapy, healthy skin is not exposed to the ultraviolet light. This may reduce the risk of premature skin aging that is often associated with  traditional phototherapy.   Continued long-term use of steroid creams can cause thinning of the skin.  Systemic therapies can affect many organ systems.

What can I expect during treatment? 
Treatment will take place in your doctor’s office. First, your doctor will determine the best dosage level for you. Then the assistant will place the hand piece directly on the lesions and apply the laser therapy. You will hear a gentle hum and see a blue-colored light from the hand piece tip. Most treatments take only a few minutes.

Does treatment hurt? 
No. Most patients experience no pain or discomfort. A few patients may feel slight warmth shortly after treatment. This warmth is mild and short-lived. No anesthesia is needed.

How many treatment sessions will I need? 
We create a customized course of therapy for you based upon the extent, thickness, and location of the lesions. Some patients enjoy clearing after about 8 sessions.  Sessions are twice per week.

How do I prepare for treatment? 
No extensive preparation is required for laser therapy. Just ensure that the skin to be treated is clean, dry, and free of any make-up, lotion, or creams containing SPF protection.

Are there side effects? 
The side effects of laser therapy are minimal. Most patients report no side effects. A few patients have reported a mild and short-lived redness at the lesion site. More serious side effects such as blistering and hyperpigmentation are rare and short-lived.  Uncommonly the procedure may not be helpful.

Are laser treatments covered by insurance? 
Many national, state, and local insurance companies cover the laser treatment, but coverage levels will vary by plan. A physician consultation is required prior to scheduling the laser treatment.
