Uvb Phototherapy Lamp For Psoriasis

What Is Narrowband Uvb Phototherapy

UVB Lamp for Treatment Psoriasis Vitiligo Eczema Atopic Dermatits HOME Phototherapy

Narrowband UVB is the most common form of used to treat skin diseases. “Narrowband” refers to a specific wavelength of ultraviolet radiation, 311 to 312 nm. UVB phototherapy was formerly provided as a broadband source .

The narrowband range of UV radiation has proved to be the most beneficial component of natural sunlight for psoriasis. Narrowband UVB may also be used in the treatment of many other skin conditions including atopiceczema, vitiligo, pruritus, lichen planus, polymorphous light eruption, early cutaneousT-celllymphoma and dermographism.

Skin conditions treated with narrowband UVB
  • Exposure times are shorter but of higher intensity.
  • The course of treatment is shorter.
  • It is more likely to clear the skin condition.
  • Longer periods of remission occur before it reappears

Uv Light Therapy For Moderate To Severe Cases

, also known as UV light therapy, is one of the most effective treatments for psoriasis. It involves exposing the skin to controlled amounts of ultraviolet radiation similar to that from the sun. It is usually prescribed with other treatments when conservative therapies fail to provide relief and is especially useful for moderate to severe psoriasis covering large portions of the body.

Phototherapy is performed in a dermatologist’s office under controlled conditions. Side effects tend to be mild. In addition to psoriasis, phototherapy may also be used to treat eczema, vitiligo, lichen planus, and cutaneous T-cell lymphoma.

The Process Is Usually Divided Into Two Phases:

  • Patients need a few consecutive daily treatments with narrowband UVB to bring their skin into the desires state.
  • Only weekly treatment is required then, to maintain the treatment effect and ensure that the disease doesnt come back.
  • To reach the fullest effect, you should start with a week of minimum exposure to the light no more than 30 seconds for each affected area per day. After reviewing the results, you can gradually increase this time up to one minute. Your main goal should be in finding the minimum exposure time for the best effect its a peculiarity of UVB narrowband psoriasis treatment.


    • Only the affected skin areas must be exposed to UVB lamp light
    • One must not undergo more than 2 weeks of treatment without breaks

    Challenges To Light Future Research Directions

    Although light therapy is effective for psoriasis, there are serious, serious roadblocks, Katz stressed, including both financial and time commitment barriers.

    The reimbursement for light therapy is moderately low and patients are expected to come in for therapy two to three times per week for at least 8 to 12 weeks, according to Katz. Also, insurers may not always cover a visit and a light treatment on the same day. Many offices do not offer either narrowband or excimer laser because its not economically feasible, she added.

    As a dermatologist, you need to be able to afford to offer light to patients, she told Healio. You have to dedicate part of your real estate to a light box and you have to dedicate your staff to light therapy. You have them assisting and delivering light. You need people who are properly certified and trained, you need to be able to offer light to enough patients to pay for that real estate.

    However, Katz also said that the overall cost of phototherapy is much less than the cost of any of the biologics.

    Economic research is needed that show these challenges, Katz said.

    I would love to see economic studies that essentially force the hand of perhaps the insurers to restructure the way in which they cover this very valuable and safe treatment for patients, she said. Were talking about great cost savings to everyone. That really is a concern.

    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.

    Treatments With Uvb And Uva

    • Psoralen and UVA light therapy , which combines UVA exposure and a medicine that makes your skin more sensitive to light.
    • The Ingram regimen, which combines dithranol, tar products, and UVB phototherapy.
    • The Goeckerman treatment, a combination of tar products and UVB phototherapy.

    Your body is exposed to UV light from banks of light tubes that give off either UVB or UVA light in a booth. Booths come in several designs. Some look like phone booths and you can stand in them. Others look like tanning beds and you can lie down during treatment. The booth will record the total amount of light you are exposed to.

    In general, your entire body is exposed to the light. You will wear sunglasses that block UV light and goggles or a blindfold to protect your eyes from getting cataracts. Men may also need to shield their genitals to protect them from an increased risk of genital cancer.

    Targeted Ultraviolet B Light Therapy

    Targeted ultraviolet B light therapy is applied to small areas of the body. It often involves the use of an excimer laser, excimer light, or NB-UVB light.

    If you have psoriasis over less than 10 percent of your body , this treatment might work for you.

    This approach exposes you to fewer UV rays overall, which will reduce side effects and health risks. It also results in faster clearing of the skin.

    For best results, it should be performed two to three times a week.

    Targeted UVB therapy can be used to treat:

    • plaque psoriasis
    • scalp psoriasis
    • psoriasis on the soles or palms

    Excimer lasers are more effective than excimer lights or targeted NB-UVB lights. Adults with plaque psoriasis can combine excimer laser therapy with topical corticosteroids.

    Effective Treatment Options With A Uv Lamp For Psoriasis

    Light therapy with an ultraviolet lamp for psoriasis is administered either in a medical setting such as a doctors office or can also be administered at home with the right type of lamp. Treatment must be consistent with exposure on a regular schedule for a set length of time. UV lamps for psoriasis can provide two types of UVB exposure, either broad band or narrow band, with the major difference being that the narrow band UVB lamp releases a smaller range of UV light.

    According to the National Psoriasis Foundation, UVA wavelengths are also used for treating psoriasis but are relatively ineffective unless used with a medication called psoralen, which makes the skin more receptive to the UV exposure. This treatment is referred to as PUVA and is proven to be effective at slowing down excessive growth of skin cells. Treatment with a UV lamp for psoriasis is proven to promote healing and decrease symptoms, with skin conditions generally improving within a few weeks or months. Maintaining a consistent treatment schedule with UV lamps for psoriasis treatment is key to obtaining successful results.

    Light Up Your Life And Restore Your Skin Health With A Psoriasis Lamp

    UVB Lamp for Treatment Psoriasis Vitiligo Eczema Dermatits HOME Phototherapy

    Use a psoriasis lamp if you have the chronic skin condition psoriasis. This condition, caused by an overactive immune system, is aided by phototherapy with a psoriasis lamp when its ultraviolet light targets the cells of the skin in the top layer. This can aid in reducing plaque formation by damaging those skin cells, and it can reduce symptoms over time.

    How is light therapy effective for psoriasis?

    The National Psoriasis Foundation asserts that light therapy is an effective and recommended treatment for psoriasis. Ultraviolet B, or UVB, is present within natural sunlight. Psoriasis lamps recreate this natural phenomenon. This type of light works by penetrating the top layer of the skin and slowing the growth of those skin cells that are affected. Treatment with UVB is offered in a few different ways: small units for such localized areas as the feet or hands, handheld units, and full body units. Some use LED bulbs others use traditional UV bulbs.

    How long does phototherapy take for psoriasis?

    While every individuals response to the treatment varies as regarding the time it takes to show results, the average is between 4-10 sessions before results are seen. Narrowband UVB treatment time depends on the specific case of psoriasis. It is important to keep up the sessions in order to see results the recommended treatment frequency is twice per week, with at least a 48-hour span between treatments.

    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.

    Who Is Light Treatment Recommended For

    Typically, phototherapy for psoriasis is only recommended for more moderate or severe cases of plaques. Initially, the doctor will likely recommend proper and consistent skincare, usually including topical ointments. If the plaques do not improve or worsen, your doctor may suggest ultraviolet light therapy. Often, phototherapy is administered in conjunction with skincare treatments and oral medications.

    How this underused treatment can help

    When ultraviolet light hits skin, it does all kinds of things, says Steven Feldman, MD, PhD, a professor of dermatology at the Wake Forest University School of Medicine in Winston-Salem, N.C. Ultraviolet light kills the immune cells in the skin that contribute to psoriasis, and research suggests that UV light may also disrupt the faulty signals between immune cells and skin cells that lead to psoriasis lesions.

    With relatively few side effects, phototherapy is an effectiveyet underusedtreatment, experts say. Phototherapy is a great treatment to start with, says Kathy Kavlick, RN, community outreach nurse for the Murdough Family Center for Psoriasis in Cleveland. Some people get really good results from it.

    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.

    What Is The Role Of Phototherapy In The Treatment Of Plaque Psoriasis

    Initiate phototherapy only in the presence of extensive and widespread disease . Resistance to topical treatment is another indication for phototherapy.

    The 2 main forms of phototherapy are ultraviolet B irradiation and psoralen plus ultraviolet A irradiation . Proper facilities are required for both UVB irradiation and PUVA photochemotherapy.

    UVB irradiation uses light with wavelengths of 290-320 nm . Narrow-band UVB phototherapy uses a fluorescent bulb with a narrow emission spectrum that peaks at 311 nm. This selective and relatively longer wavelength is more effective than broadband UVB for the treatment of plaque-type psoriasis, and poses less risk of burning. Excimer laser UVB therapy can deliver high-dose light to limited plaques.

    UVB therapy is usually combined with one or more topical treatments. The Goeckerman regimen uses coal tar followed by UVB exposure and has been shown to induce disease remission in more than 80% of patients. The Ingram method comprises anthralin application following a tar bath and UVB treatment. At present, UVB is more commonly combined with topical corticosteroids, calcipotriene, tazarotene, or simply bland emollients. Etanercept and narrow-band UVB combination therapy reportedly was successful.

    Home ultraviolet therapy can overcome some of the logistical problems associated with phototherapy. Because of the expense of the home units, it is most suitable for patients who require long-term maintenance therapy.

    Can Anyone Who Has Psoriasis Use Phototherapy

    While dermatologists prescribe phototherapy for many people, it is not recommended for anyone who has:

    • Had a melanoma or any other type of skin cancer

    • A medical condition that makes you more likely to develop skin cancer, such as Gorlin syndrome or xeroderma pigmentosum

    • A medical condition that makes you sensitive to UV light, such as lupus or porphyria

    • To take medicine that makes them more sensitive to UV light, such as some antibiotics, diuretics, and antifungals

    Which Type Of Light Is Best

    UVB Light Treatment for Psoriasis (before and after) – My Story

    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 The Risks And Downsides Of Light Therapy For Psoriasis

    While light treatment for psoriasis is an effective treatment for uncomfortable and embarrassing plaques, it is not without its risks. With any UV exposure, including that of the natural sun, you are at a risk of skin cancers. This is true of both UVB and UVA treatments, though the latter is more problematic. The longer exposure required for UVA light therapy, and especially the risks of the drug psoralen, can put you at a greater risk of cancer or other skin diseases. As a result, it is recommended that patients receive no more than 150 UV light treatments of either type in their lifetime in order to mediate the risks associated with them. With this cap and a doctors careful assessment of your specific case, however, the benefits of treatment if prescribed will likely outweigh the risks.

    Psoriasis can be a very uncomfortable and isolating condition. While diligent skincare and the use of medication and ointments can help reduce your psoriatic plaques, these measures may not be enough to control your condition. UVB light therapy has shown great results for many who have undergone this treatment, and could yield amazing results for you as well.
