blue light therapy for psoriasis

Blue light therapy for psoriasis, or phototherapy, is widely in use in the management of psoriasis.
There are many potential sources, knowing that the most popular and most prescribed is by using ultraviolet. These correspond to wavelengths ranging from 290 to 340 nm with today’s preference for the TL01 narrow band TL01 of 311 nm.

You can also treat plaque psoriasis with dynamic phototherapy, that is to say locally apply a photosensitizing agent (aminolevulinic acid) followed by irradiation of visible blue or red light, to be differentiated from localized or generalized balneopuvatherapy, which consists of applying meladinine solution during a bath before irradiation with ultraviolet A.

The blue light therapy for psoriasis

According to various criteria such as the proportion of the body affected by the disease and the importance of the symptoms grouped in the PASI score (Psoriasis Area Severity Index), there are 3 types of psoriasis, light forms, moderate forms and severe forms.

  • For moderate to severe forms, systemic treatments are often prescribed: phototherapy (UVB therapy, puvatherapy).
  • For mild forms, local topical treatments such as dermocorticoids or vitamin D derivatives are particularly indicated.
  • However, localized phototherapy may also be proposed whether it is puvatherapy, balneopuvatherapy or UVBtherapy, especially in palmoplantar attacks.

Recently, treatments with blue LED light has been successful. Here, it is not about UV but of a light from a non-toxic action, without a risk of occurrence of cutaneous cancer.

What is blue LED light?

LEDs are electroluminescent diodes that consume very little energy. Blue light has a wave of 453 nm. It is part of the visible radiation and does not contain UV whose wavelengths are between 290 and 340 nm.

How does blue light work?

It has anti-proliferative properties. It notably reduces the proliferation of keratinocytes while promoting their differentiation. In psoriasis which is a disease in which epidermal cells proliferate, blue light can prevent this hyperproliferation.

It also intervenes on immune cells by regulating T lymphocytes and reducing cytokine production. It therefore has a double action on the inflammatory process and keratinocyte proliferation.

Several studies tend to show its effectiveness in mild psoriasis. A first experiment was made in 2009 by Weinstabl A et al on 40 patients with mild to moderate psoriasis for 4 weeks, with positive results.

A second clinical study took place in 2014 in 47 patients over a longer period of 4 months. The patients were in full control, one plate was under treatment with blue light in comparison to another untreated.

The value of the local PASI based on starting index of about 5.2 improvement by an average of 50% during the 12 weeks of treatment with blue LED light exposure. No adverse effects related to blue LED light were observed.

There is a device available today

This is the Blue Control device from Philips which is freely available on Amazon. blue light therapy for psoriasis

It is a portable phototherapy device for home treatment. The treatment must be daily and must last 30 minutes per plate. I highly recommend it for the local attacks on the limbs (arms, legs, elbows, knees, back of the hands). You just need to strap the device at the level of the problem.

This is a new treatment for mild to moderate psoriasis. The psoriasis plaques should be well limited however, it should be known that the treatment is long, that it lasts several weeks or months but that it gives excellent results: 50% of improvement in 12 weeks.

The investment is quite low in the long term, which corresponds to the purchase of equipment, considering the results you will have with this blue light therapy for psoriasis, saving you on the regular purchase of some costly medications such as ointments, creams, etc., and it is safe to use at home at any time of the day and it is pleasant to use and has no side effects.

    Blue light therapy sound to be very beneficial for people with psoriasis, I was wondering are there many people who suffer from this condition?

    Have you ever heard of using essential oils for psoriasis, I read an article the other day about using essential oils can be helpful for some people?

    • John

      Thanks for taking the time to read and comment on my article Jeffrey. According to latest statistics, a total of 125 million people in the world suffer from psoriasis at various degrees, 7.5 million of them are Americans. We know that people with a poor immune system are prone to suffer from this disease, therefore people with HIV or stress are most likely to get it. As we know, there is no total cure for it, but studies has helped us to find many ways to control it so that a psoriasis suffer can live with it very comfortably in most cases.

      When someone asks me how to get started with a plan to help with their psoriasis, my recommendation is to first go on a diet. There are some great diets designed especially for psoriasis sufferers here: A Skin Disorder Diet 

      This will already help and at the same time find out what plan or treatment will work best.

      The blue light therapy is a very efficient way to go about it, especially is countries where there is so much sun (England for example), or for someone who works long hours and cannot find spare hours to sit in the sun, or if the affected areas are in places one cannot expose publicly. The blue light having the same effects as the sun rays.

      You are quite right Jeffrey, some essential oils work very well for this and other skin conditions. One that I can personally recommend for having successfully tested it myself, is the Salve-ation Eczema & Psoriasis Essential Oil Blend by Davina, available on Amazon at a very good price.

      I hope to have answered your question clearly Jeffrey and I hope to see you here often.

      I wish you the very best of health.


  • Michael Miller

    Thanks for the thorough breakdown of how blue light therapy can help cure psoriasis. My wife uses one and it really helps with seasonal depression. I didn’t know it could help with other issues. I like how you included scientific studies and their results. Psoriasis is such a painful illness and it is nice to know their are proven treatments without harmful side effects.

    • John

      Thanks for visiting my website and for your comment Michael. Yes, bleu light therapy works well for psoriasis. Psoriasis sufferers know very well that moderate exposure of affected areas to the sun helps to reduce the problem, and it is natural. Blue light has the same effects. As your wife knows, it is beneficial for several other issues and often used for muscular pains. Athletes use it a lot. There are also other ways to reduce psoriasis problems such as the use of natural remedies, some of them are listed in one of my past articles: “5 Excellent Psoriasis Natural Treatments Home Remedies“.

      I wish you and your wife the very best of health,

    Very informative article about psoriasis.I gathered a lot of information about psoriasis from your post. Still, I wonder if the psoriasis is curable. Instead of using creams and tablets the treatment by radiation seems to be great. My only worry is if it can cause side effects like causing cancer when used for longer duration.

    • John

      Thanks for visiting my website and for taking the time to comment and ask questions Prabakaran. I am glad that it helps you. Unfortunately, as of today, psoriasis is not completely curable, but thanks to progress in various directions, we can now keep it under control to the point that it can become totally bearable, in some cases it can even feel like it is cured.

      The purpose of this website is to let my readers know that formal medical treatments such as tablets, creams, ointments, etc. have side effects, sometimes disastrous side effects. My goal is to point out that there are alternative treatments that work as well, if not better, and that are totally side effects free. Some of them I am using myself.

      You can consider blue light therapy like exposing the affected parts of the body to the sun, which is the first thing that is recommended to a psoriasis sufferer, it must be done in moderation and when done correctly, there is no risk of damage, or cancer, and no side effects.

      I hope to have cleared up the subject, but if you have any more questions, please do not hesitate to ask them here for a rapid response.

      Best wishes and the best of health to you and your family.

    Modern medicine has come so far. I didn’t even know they could do that with lights. I guess it’s true that you learn something new every day.

    Hopefully they find a permanent cure for this condition soon. I can’t imagine going through it but I’m glad there are people like you who choose to help other people going through the same struggles.

    • John

      Thanks very much for your interest in this website Amazon LaShaun, and for your kind words. A lot of progress is being done on this skin problem, but unfortunately nothing permanent can be done yet. My advice to psoriasis sufferers, in the main time is to keep it under control, starting with a properly planed psoriasis diet, and making use of natural creams and Dead Sea Salts.

      I wish you the very best of health.

  • andreabobby

    Wow, I have never heard of this form of therapy before! I’m wondering if there have been any side effects, adverse reactions or negative results reported from undergoing blue light therapy?

    Also, since it is a fairly recent procedure, has blue light therapy been known to treat other types of skin conditions (eczema, skin tags and acne come to mind)?

    • John

      Thanks very much for your visit to my website Andrea. The only side effect with the blue light therapy has is if we overexpose ourselves to it, like overexposure to natural sunlight. It has beneficial results on other skin conditions as well. To be used in moderation also.

      I look forward to seeing you on this website again soon.
