Laser Treatment

Laser treatment for psoriasis can reduce the need for medicated creams and elimination diets. Treatments are fast, safe and effective. At The Psoriasis Institute we use several types of lasers and light devices for the treatment of psoriasis. Large areas of psoriasis are best treated with Narrowband Phototherapy, however smaller areas respond well to a 308-wavelength laser.

  • Several types of medical lasers can effectively treat psoriasis
  • The majority of patients respond after 4-5 treatments
  • Treatments are painless, and take only 1-2 minutes to perform
  • This treatment is best for small isolated areas of psoriasis

Laser uses the targeted approach for psoriasis management using intense, focused laser light. Prescribed doses of laser targets lesions of psoriasis, without harming the surrounding skin.

At the Institute we use two forms of laser therapy:

Excimer laser emits high intensity ultraviolet light delivered in a one to two second pulse. This type of laser energy can reduce the inflammation in the sites of psoriasis, and over several treatment sessions, can result in resolution of psoriasis.

Pulse dye laser (V Beam) can target psoriasis plaques by decreasing the blood vessels in areas of psoriasis. This form of laser is more involved than the Excimer procedure.

Our Specialists will determine the dose of laser used, individualising treatments depending on the thickness, location and type of psoriasis, as well as your skin colour.

The laser procedure is performed at The Psoriasis Institute’s laser suite under medical supervision. Individual areas of psoriasis are targeted with the laser, sparing non- affected normal skin. The procedure is over in a matter of minutes and patients can resume their normal activities.

Laser treatment for psoriasis is still a relatively new way of treating psoriasis, however results are very promising. Results may last up to a year, and most patients start to respond after 3-4 treatments. This form of psoriasis treatment is ideal for patients who have small areas of psoriasis. Larger areas of psoriasis respond best to narrowband phototherapy.

The Institute will be conducting medical research regarding the long term benefits of laser treatment for psoriasis.

The number of sessions will vary depending on the severity, location and type of psoriasis. Psoriasis lesions on the trunk respond best, whilst lesions on the hands and feet may take a few more treatments to clear. As a guide we recommend between 6- 12 treatments. We recommend one to two treatments per week.

Laser therapy for Psoriasis is more affordable than you may think, and in many cases partially covered under Medicare. Each treatment carries an out of pocket expense of $29! Most patients will benefit from 6-12 treatments.

Laser therapy is generally safe, however side effects maybe seen in less than 2% of cases.

Side effects of Lasers include:

  • Bruising
  • Blistering
  • Temporary darkening or lightening of treated skin
  • Temporary redness, itching, burning or stinging
  • Worsening of psoriasis if doses are too strong

Not all forms of psoriasis will benefit from laser. In fact some types of psoriasis may worsen after laser treatment. In other cases the extent of psoriasis is too great to be treated with lasers.

Laser treatment is not for everyone with psoriasis. We will guide you in regards to the suitability of this treatment-in many cases a safer alternative to laser is phototherapy.

No. To date, there is no cure for psoriasis, however laser therapy can be a quick, safe and efficient method to treat this condition. The Specialists at The Psoriasis Institute often combine laser with vitamin creams and a trigger avoidance diet to achieve great results.

The use of lasers for psoriasis is a novel solution for a relatively common but chronic disease. The advantages of lasers is that it can decrease the use of steroid creams, the treatment itself only takes a few minutes to perform and is relatively painless. The current 308 system provides the safest, yet most effective laser treatment we have trialled.  Laser therapy is not for everyone, in most situations, phototherapy is a better option.
