How Long Does Phototherapy Take For Psoriasis

Does Normal Sunlight Help

Treat Psoriasis with Phototherapy

Regular sunlight has been used for centuries to treat psoriasis and other skin conditions. Some people suggest using a sunblock on unaffected areas then covering the affected areas about 10 or 15 minutes after youve been in the sun.

You just have to be careful since sunburn can actually have the opposite effect on psoriasis and actually make it worse. Short exposure times are key.

Make sure you talk to your doctor before you decide to try sun exposure just to make sure its right for you.

Who Cosentyx Is Prescribed For

Cosentyx is approved to treat moderate to severe plaque psoriasis. The condition is considered moderate to severe if it covers 3% or more of your body. For reference, 1% of your body is about the size of your hand .

You must be able to have or systemic therapy. With phototherapy, light treats psoriasis plaques. Systemic therapy works in your whole body to stop the formation of plaques.

Cosentyx is also approved to treat active psoriatic arthritis. When the condition is active, you currently have symptoms.

Clinical trials have shown Cosentyx to be effective for treating psoriasis, including plaque psoriasis and psoriatic arthritis.

For treating plaque psoriasis, researchers looked at adults with moderate to severe plaque psoriasis. The researchers gave them either Cosentyx or a placebo . In 12 weeks, more adults who received Cosentyx reported that their symptoms eased than adults who received a placebo.

Researchers also compared Cosentyx with a placebo for treating adults with psoriatic arthritis. After 16 weeks, more adults who received Cosentyx reported that their symptoms eased than people who received a placebo.


Guidelines published by the American Academy of Dermatology recommend secukinumab, the active drug in Cosentyx, as a treatment option for adults with moderate to severe plaque psoriasis.

Tanning Beds: Yay Or Nay

The National Psoriasis Foundation, the American Academy of Dermatology, the United States Department of Health and Human Services, and the World Health Organization all discourage the use of commercial tanning beds for treating psoriasis. The spectra of light in tanning beds vary greatly and often include wavelengths of light that are carcinogenic and photo-damaging. The ultraviolet radiation from these devices can damage the skin, cause premature aging and increase the risk of skin cancer.

Q: Can Phototherapy Cause Skin Cancer

A: The connection between light exposure and the impact on skin and the resulting risk of skin cancer is not unknown. However, using UVB phototherapy has proven to be a safe and effective treatment option. Researchers have concluded that there is no increased skin cancer risk with UVB phototherapy.

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.

Palmoplantar Psoriasis And Light Therapy: Effectiveness And Safety Of Treatment

  • May 6, 2021

For millennia, people have tried to find the best ways to get rid of psoriasis. There are powerful drugs on the market today that have proven to be effective. But light therapy, which has been around for over 100 years, is an equally effective treatment that is considered non-invasive and non-addictive, unlike biological drugs.

In this article, we look at the treatment of palmoplantar psoriasis with light therapy. Based on clinical research and evidence, we will tell you how effective phototherapy is, what type of phototherapy is right for you, as well as precautions and side effects.

Narrowband Ultraviolet B Light Therapy

Narrowband ultraviolet B is the most common form of phototherapy. It can be used to treat plaque or guttate psoriasis.

NB-UVB lamps and light bulbs emit wavelengths of light between 311 and 313 nanometers , according to recent clinical guidelines on phototherapy.

Your starting dose will depend on your skin type and how easily you burn or tan.

However, NB-UVB light therapy is most effective when performed two or three times a week. An emollient such as petroleum jelly may be applied before each session.

According to a 2002 , people who had twice-weekly sessions saw their symptoms clear up in an average of 88 days. Those with sessions three times a week saw their symptoms clear up in an average of 58 days.

Once the skin is clear, maintenance sessions can be performed on a weekly basis.

A 2017study showed that around 75 percent of people receiving NB-UVB treatments found it cleared their psoriasis or led to minimal symptoms. They used fewer prescription creams for their condition, too.

NB-UVB treatments may prove more effective when combined with topical treatments, such as vitamin D analogues and corticosteroids.

Are The Solrx Models With More Bulbs Physically Larger Devices

No. For a given device family, all models use the same steel frame components and differ only in the number of bulbs installed. For example, the eight-bulb 1780 uses the same main frame as a four-bulb 1740, but the bulbs are packed in much tighter to increase the device irradiance and reduce treatment times. Devices with more bulbs will also have more ballasts, and be a bit more heavy.

Recommendations For People Undergoing Uvb Or Puva Phototherapy

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

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.

What Are The Possible Side Effects

UV light therapy can have various side effects. For instance, the radiation can dry out your skin and cause itching. So people are advised to thoroughly moisturize their skin with a lipid-replenishing skin care product immediately after the treatment. Light therapy also often causes sunburn-like skin reactions. In rare cases, blistering burns may occur.

In people who tend to get cold sores on their lips, light therapy might make cold sores more likely. Applying sunscreen to your lips before the treatment can help prevent cold sores. Taking psoralen for PUVA therapy can cause nausea and vomiting. These side effects don’t occur when psoralen is used as a bath solution.

Other, less common, side effects include raised red patches that go away again after a few days and hair follicle infections.

In order to limit side effects as much as possible, it’s important to avoid natural sunlight on the day of treatment, or protect yourself when outdoors by wearing appropriate clothing, sunglasses and sunscreen. It is particularly important to avoid further exposure to sunlight after PUVA therapy.

Another disadvantage of UV light therapy is that it involves a lot of doctors’ appointments and takes up a lot of time overall. So people who are busy, for instance with their work and family, might find it hard to stick to this treatment in everyday life.

How Long Has Ultraviolet Phototherapy Treatment Been In Use

How Long Does Phototherapy Take for Psoriasis ...

The benefits of UV phototherapy for psoriasis was recognized by the medical community as early as 1925 by a study of the effects of natural sunlight on psoriasis patients. Devices to produce artificial light for the treatment of psoriasis have been in use for over 50 years and today there is a phototherapy clinic in most cities. Home units are a more recent phenomenon, as lower costs have made them more attainable to the average person. This remarkable ancient Egyptian wall carving shows a sick infant being treatedwith sunlight, probably for infant jaundice . Today, affected babies receive the same treatment, albeit from artificial light sources. The therapeutic rays are inthe UVA spectrum in this case. Our bodies evolved in an environment bathed in ultraviolet light, so we developed responses to use the light beneficially and to protect us from over-exposure . Our modern lifestyles being fully clothed, having protection from the sun, and many of us living in extreme northern/southern latitudes has significantly reduced our UV exposure and contributed to health problems in some.

What Are The Adverse Effects Of Uvb Phototherapy

Sometimes uncomfortable sunburn will occur, at its worst about 8 hours after treatment. This fades over the next few days and should be treated with frequent and liberal emollients.

The effect of UVB is similar to the effects of sun exposure. Excessive exposure contributes to ageing skin and to the risk of skin cancer.

How Much Room Do I Need For A Solrx 1000

The SolRx 1000-Series Full Body Panel is designed to take up a minimum amount of space in your home. They are only 3½ thick by 29 wide by 72 high and mount flat up against a wall, or in a corner, with the bottom resting on the floor and the top fastened to the wall in two places. Casters are not practical because they must have a wide wheelbase to keep the unit from tipping over, and therefore greatly increasing the floor space needed. Casters also increase the distance between the bottom of the bulbs and the floor, making a platform necessary for lower leg treatment. Over 25 years of experience with the 1000-Series has shown that once the device is mounted, it is out of the way and there is little need to have it moved. The authors personal 1000-Series unit was in the same place for over 20 years, until just recently being replaced by an E-Series 1M+4A.

Psoralen Plus Ultraviolet A Therapy

This approach uses ultraviolet A light with psoralen, a medication that increases your sensitivity to light. Psoralen can be:

  • taken orally
  • applied topically

In general, PUVA is highly effective but not widely used or available.

Oral PUVA comes with the highest risk of drug interactions and side effects . Its most effective when combined with an oral retinoid.

Bath PUVA works best for adults with moderate to severe plaque psoriasis.

Its performed more often in Europe than in the United States. This is primarily because it uses trimethylpsoralen, a form of psoralen that the Food and Drug Administration hasnt approved.

Topical PUVA may be of particular benefit to adults with palmoplantar psoriasis or palmoplantar pustular psoriasis. It can also be used for localized psoriasis.

Other types of phototherapy that either arent as effective, widely recommended, or widely used are described below.

What Complementary And Alternative Treatments Help Psoriasis

Complementary and alternative therapies are sometimes used to improve symptoms of psoriasis.

Although most of these approaches are safe, you should talk to your doctor before trying any new treatment or technique.

Examples of complementary and alternative methods commonly used to treat psoriasis include:

Diet and Nutrition Some people report improved symptoms by altering their diets or taking certain supplements. You can also try avoiding specific dietary triggers that may increase inflammation and worsen your symptoms.11

Sunlight Exposure to small amounts of sunlight can reduce some symptoms of psoriasis. But too much sun can worsen outbreaks and increase your risk of skin cancer. Talk to your doctor about how much sunlight exposure is safe for your situation.

Daily Baths Soaking in mineral water baths may help hydrate and soften the skin. You can add colloidal oatmeal, Epsom salts, or Dead Sea salts to bathwater to help calm inflamed skin. But stay away from hot water and harsh soaps, which can worsen your symptoms.

Moisturizer Some people report fewer symptoms when they apply moisturizer to affected areas. Ointments can help lock in moisture better than creams.

Yoga and Meditation These practices can clear your mind and reduce stress, which may ease symptoms of psoriasis.

Exercise Physical activity increases the production of chemicals known as endorphins, which improve mood and energy. Exercise can also help you sleep better and reduce anxiety.

What Are The Side Effects Of Phototherapy

Side effects Phototherapy is very safe, but it can have temporary side effects, including skin rashes and loose stools. Overheating and dehydration can occur if a baby does not get enough breast milk or formula. Therefore, a babys skin color, temperature, and number of wet diapers should be closely monitored.

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 Are The Risk Factors For Psoriasis

Does phototherapy help psoriasis?

While anyone can develop psoriasis, the following factors can increase your risk:

Family History Having one parent with psoriasis increases your risk, and having two parents with the condition puts you at greater risk.

Infections People with HIV are more likely to develop psoriasis. Additionally, strep throat has been linked with the development of a certain type of psoriasis, called guttate psoriasis. This causes small, round, scaly rashes to develop, usually on the trunk and arms. Kids and young adults with this type of recurring infection may be at increased risk.

Stress Since stress can impact your immune system by causing inflammation, high stress levels may increase your risk of psoriasis.

Obesity Being overweight or obese increases your risk, and psoriasis often develops in the creases and folds of skin.

Smoking Smoking tobacco increases your risk and the severity of psoriasis, and may initiate the development of the disease.
