Light Box Treatment For Psoriasis

Which Type Of Light Is Best

Daavlin Home Phototherapy for Psoriasis and Vitiligo

There are two types of light therapy for psoriasis. UV light therapy can be accomplished with either UVA or UVB light waves. UVA lights penetrate deep under the skin, and it can be hard for the skin to absorb and utilize the light. When your doctor uses UVA light for therapy, you will also need to take a drug called psoralen, which helps your body to absorb the light and to experience its effects on the psoriatic plaques. UVB light can also be utilized for the treatment of psoriasis. The wavelength is well controlled and is usually applied in a measure of 311, 312 or 313 nanometers. The very specific wavelength only impacts the top layers of the skin and helps to target psoriasis while limiting the side effects of UV exposure.

The type of light treatment that your doctor recommends for you will be based on many factors. Because UVA light therapy is a more invasive treatment, it is typically reserved for individuals whose quality of life and health are most impacted by their psoriatic plaques. Additionally, your skin type and overall health will be considered. If you have fair skin that is easily susceptible to skin damage, or already have risk factors that would complicate your treatment with either of the ultraviolet lights or the psoralen, your doctor will use that information to inform your treatment plan.

What Are Ultraviolet Rays

Sunlight contains a wide range of wavelengths more than just visible light. Long wavelengths, invisible to our eyes, are called infrared and we feel these as heat from the sun. Shorter wavelengths are also invisible to us and these are called ultraviolet . They can cause suntan and sunburn, and also carry the risk of skin cancer to some individuals after high- and long-term exposure.

Ultraviolet B is the short wavelength range of UV light that only penetrates the superficial layers of the skin. It is the main cause of sunburn. We are all at risk of sunburn, but those of us with very fair skin are most at risk.

Ultraviolet A is the longer wavelength range of UV and forms the greater part of the suns UV content. It causes tanning more than sunburn. It penetrates the skin deeper than UVB and can also penetrate window glass, including car windows.

Recommendations For People Undergoing Uvb Or Puva Phototherapy

  • Courses of phototherapy are much more effective if administered without interruption. So, attend every appointment and avoid arranging a holiday during a phototherapy programme.
  • Please inform your phototherapist nurse if you have been started on any new medication, as some medicines make you more sensitive to UV light.
  • Dry, itchy skin can be treated by creams such as aqueous cream or emollients these are available on prescription and over the counter. It is advisable not to use bubble baths as these can dry out the skin. Instead, add prescribed bath oils or emollient to the bath water and soak the body for 10-15 minutes.
  • Women of childbearing age should not become pregnant while having PUVA, but previous use of PUVA does not affect subsequent pregnancies.
  • Do not wear deodorants, perfume or aftershave during treatment. Some of them contain chemicals which sensitise the skin to UV light and may result in a sunburn reaction.

Are There Side Effects Or Risks

Light Therapy

Some patients experience a reaction similar to sunburn or blistering at the site of the treated area and in some cases, an increase in pigmentation may occur. However, there is no effect on your other skin or systemically.

Results may vary, so talk to your doctor about the best treatment option for you.

Xtrac For Vitiligo It Doesnt Have To Last Forever

Vitiligo is unfortunately an extremely difficult condition to treat, and most other treatments may not be very successful. XTRAC treatments can minimize and, in many cases, even eliminate vitiligo depigmented patches. The XTRAC excimer laser delivers a targeted beam of UVB light and only the areas of skin affected by vitiligo receive the laser energy.

Though the laser spot size measures only 18mm x 18mm, due to rapid exposure times, relatively large, discrete areas can be treated in just five to 10 minutes. And most importantly, XTRAC treatments achieve complete response rates faster in a higher proportion of patients.

Particular areas, such as the face, neck and scalp often respond well with the XTRAC procedure, although more sessions are typically required than for psoriasis.

What To Discuss With Your Dermatologist

If you use phototherapy to treat psoriasis, your dermatologist will check you after you have had a certain number of treatments, usually four to six in the beginning. These checkups are essential, so be sure to keep all of your appointments.

During these appointments with your dermatologist, you should tell your dermatologist if you have:

  • Any side effects

  • Worsening psoriasis after phototherapy

  • Missed more than two appointments

If you miss appointments, its unlikely that phototherapy will be helpful for you. Research shows that patients see steady improvement only when they receive phototherapy two to five times per week.

What Is Red Light Therapy

Psoriasis treatment – UVB light therapy / phototherapy – Psoriasis diary

RLT is a form of light therapy that uses light emitting diodes to treat conditions from acne to persistent wounds. Some people with psoriasis undergo light therapy with ultraviolet rays, but RLT doesnt contain any UV rays.

In a hospital setting, when RLT is combined with certain medication, it may be referred to as photodynamic therapy.

You dont necessarily need to see a doctor to test out RLT. There are various consumer products on the market aimed at cosmetic applications. Many tanning salons, like B-Tan Tanning in parts of Florida, Pennsylvania, New Jersey, and Delaware, offer red light beds. These salons say that red light beds help reduce:

  • cellulite

Broadband Ultraviolet B Light Therapy

Broadband ultraviolet B light therapy is an older form of phototherapy than NB-UVB. The two treatments are similar.

However, BB-UVB lamps and light bulbs emit wavelengths of light between 270 and 390 nm.

As with NB-UVB, your starting dose will depend on your skin type.

According to a small 1981 study, 90 percent of people had clear skin after having sessions three times a week and an average of 23.2 treatments.

One hundred percent of people had clear skin after having sessions five times a week and an average of 27 treatments.

BB-UVB is considered less effective than NB-UVB and is more likely to cause side effects. It should be reserved for instances where NB-UVB isnt a treatment option.

BB-UVB is most effective for plaque psoriasis, although it can also be used for guttate psoriasis.

It can be prescribed as a monotherapy or alongside retinoid acitretin . In combination therapy, the skin clears up faster, and lower doses of UVB can be used.

What Kinds Of Light Therapy Are There

Different forms of light therapy vary according to the type of light exposure and whether its combined with medication. Ultraviolet B can be delivered as broadband UVB or narrowband UVB . BB-UVB therapy was developed first, but NB-UVB is now more commonly used for its effectiveness and fewer side effects. A benefit of narrowband UVB is that patients are exposed to a more specific and therapeutic wavelength of light. UVB phototherapy is used to treat moderate to severe psoriasis.

For people with more advanced psoriasis, another form of light therapy combines ultraviolet A with a psoralen drug . In this combination therapy, known as PUVA, the patient takes the medication shortly before light treatment to boost the lights effect on the immune system.

A study published in April 2013 in the American Journal of Clinical Dermatology found that PUVA therapy was most effective among adults with moderate to severe plaque psoriasis. According to the study, between 60 and 75 percent of patients overall who received some type of light therapy achieved at least 75 percent improvement in their condition. The results were based on the Psoriasis Area and Severity Index, an assessment tool used to score a persons condition according to disease progression.

PUVA isnt without side effects, however, including a heightened risk of skin cancer, severe burn, and nausea.

Tablets Capsules And Injections

If your psoriasis is severe or other treatments have not worked, you may be prescribed systemic treatments by a specialist. Systemic treatments work throughout the entire body.

These medications can be very effective in treating psoriasis, but they all have potentially serious side effects. All the systemic treatments for psoriasis have benefits and risks. Before starting treatment, talk to your doctor about your treatment options and any risks associated with them.

If you’re planning for a baby, become pregnant or are thinking of breastfeeding, you should also speak to your doctor first before taking any new medicine to check it’s suitable for use during pregnancy or breastfeeding.

There are 2 main types of systemic treatment, called non-biological and biological .

What Is Excimer Laser Therapy And How Does It Work To Treat Plaque Psoriasis

Uv Light Box For Psoriasis

Another type of phototherapy treatment is delivered using an excimer laser. The excimer laser delivers a high-intensity beam of ultraviolet light. This type of phototherapy is similar to narrow-band UVB in that it specifically targets the areas of skin that are affected by psoriasis symptoms. This can help to reduce side effects because only the affected skin is exposed to the ultraviolet light1.

Excimer laser treatment is usually recommended for adults and children with mild or moderate psoriasis. It can also be effective in treating psoriasis that is difficult to reach with other types of treatment, such as symptoms on the scalp, palms, and soles of the feet. Patients generally receive treatment twice per week and generally see an effect after 4-10 treatment sessions2.

Excimer laser treatment can cause side effects including blisters, burning, and reddened skin. Because it is a relatively new type of treatment, the long-term effects of excimer laser treatment are not yet fully known 3.

Ultraviolet Light Services To Treat Chronic Skin Disorders

Our phototherapy treatment unit offers a broad range of ultraviolet light services for chronic skin disorders such as psoriasis, vitiligo and atopic dermatitis, and other light-responsive conditions such as contact dermatitis, mycosis fungoides, actinic keratoses and acne. Our doctors and nurses provide individual treatment programs, and the unit is self contained in our office, so your check-in, treatment and check-out are seamless and efficient.

The unit offers a broad range of treatments including:

  • Ultraviolet B light therapy
  • PUVA
  • Excimer laser

Ultraviolet B light therapy is often used in the treatment of psoriasis and other light responsive diseases. It is also called narrow-band UVB, which is a specific wavelength of light that is effective in treating diseases like psoriasis. The treatments are administered in upright booths lined with fluorescent bulbs. UVB therapy is usually prescribed for multiple days per week for multiple weeks.

Your provider will prescribe the intervals most appropriate for you.

Photodynamic therapy involves the activation of a photosensitizing drug by a visible light source. Precancerous or cancerous skin cells take up and retain the drug better and longer than normal cells allowing selective destruction of those cells upon exposure to the light source. PDT is most commonly used for the treatment of actinic keratosis, acne, skin cancer and sometimes for cosmetic improvement of the skin.

Narrowband Uvb Light Therapy

Sunlight and ultraviolet light slow the rapid growth of skin cells. Psoriasis patients are directed to carefully sunbathe. People with psoriasis all over their bodies may require treatment with light boxes for full body exposure. We are equipped with the latest light treatment technology available.

Narrowband UVB light treatment uses the optimal part of the UVB light spectrum which slows the growth of psoriasis lesions or re-pigmentation of one’s natural skin coloring. Exposure time of narrowband UVB lamps can be longer than with traditional broadband UVB yielding more effective results. Recent studies have shown 75% clearing with narrowband UVB. Erythemal response is nearly eliminated with narrowband UVB light.

Risks and side effects of other treatments, such as systemic drugs have not been found with narrowband UVB light therapy.

Combining Phototherapy With Other Treatments

Phototherapy is often combined with other types of treatments for psoriasis, including certain types of systemic medicines and topical medicines3. Healthcare providers will provide specific advice about which treatments are safe to combine with phototherapy. During the phototherapy sessions, patients wear protective eyewear and shield sensitive areas of the body from exposure.

How Is Puva Treatment Administered

Like UVB treatment, PUVA is administered in hospital phototherapy or physiotherapy units. As with UVB phototherapy, there are different methods for deciding on a starting dose of UVA and how to increase the dose to a therapeutically effective level. Some centres measure the sensitivity of the individuals skin to PUVA by applying test doses to small areas of skin, in a similar way to the MED test described previously. Because PUVA involves sensitising the skin before UV exposure, the sensitivity testis called the minimal photosensitivity dose test. Other centres may use phototype-based treatment schedules or a table of doses.

Treatment times for bath PUVA are shorter than for tablet PUVA and may range from less than a minute up to 5-8 minutes, depending on the output of the PUVA cabin and the dose scheme used. Tablet PUVA times may extend to15 minutes or more. If any session produces a sunburn reaction, or if any other symptoms are reported, the subsequent doses may be altered.

Bath PUVA phototherapy is usually given twice a week or three times every fortnight, whereas tablet PUVA is usually given twice a week for 15-25 treatment sessions or until the psoriasis has cleared to an acceptable amount.
