How Light Therapy Can Help Treat Psoriasis
If you suffer from psoriasis, you have probably tried various treatments to reduce symptoms. One option that has shown promise is light therapy, also known as phototherapy. This treatment involves exposing your skin to specific wavelengths of light to reduce inflammation and improve skin cell growth. Learn more about the benefits of light therapy for psoriasis and how it can help improve your skin condition in this article.
What is Light Therapy for Psoriasis?
Light therapy for psoriasis is a treatment that uses ultraviolet (UV) light to reduce inflammation and improve skin cell growth. There are different types of light therapy, including narrowband UVB, broad-spectrum UVB, and UVA. Narrowband UVB is the most commonly used type of light therapy for psoriasis because it is effective and has fewer side effects than other types of UV light. During a light therapy session, you will stand in a light box or receive targeted light therapy to affected areas of your skin.
How does Light therapy work for Psoriasis Treatment?
Light therapy for psoriasis works by slowing down the growth of skin cells and reducing inflammation. UV light penetrates the skin and slows down the production of skin cells, which is a key factor in the development of psoriasis. UV light can also help reduce inflammation in the skin, which can help reduce symptoms like redness, itching, and scaling. Light therapy is a safe and effective treatment option for psoriasis, but it is important to work with your doctor to determine the best type and frequency of treatment for your individual needs.
What are the benefits of Light Therapy for Psoriasis?
Light therapy for psoriasis has several benefits. It is a safe and effective treatment option that can improve the appearance and symptoms of psoriasis. It is non-invasive and does not require the use of medications, which can have side effects. Light therapy can also be used in combination with other treatments, such as topical creams or oral medications, to enhance their effectiveness. Light therapy can also be customised to meet the individual needs of each patient, making it a versatile and flexible treatment option.
What are the different types of Light Therapy for Psoriasis?
There are several types of light therapy that can be used to treat psoriasis. The most common types include UVB therapy, PUVA therapy, and laser therapy. UVB therapy involves exposing the skin to UVB light, which can help to slow down the growth of skin cells and reduce inflammation. PUVA therapy involves taking a medication called psoralen and then exposing the skin to UVA light. This can also help to slow down the growth of skin cells and reduce inflammation. Laser therapy uses a targeted beam of UVB light to treat specific areas of the skin affected by psoriasis. Your doctor can help you determine which type of light therapy is best for your individual needs.
What are the potential side effects of Light Therapy for Psoriasis?
While light therapy is generally considered safe and effective for treating psoriasis, there are some potential side effects to be aware of. These can include redness, itching, and burning of the skin, as well as an increased risk of skin cancer with long-term use. It’s important to discuss any concerns or questions you may have with your doctor before starting light therapy for psoriasis. They can help you weigh the potential benefits against the risks and determine if this treatment option is right for you.
Who is a good candidate for Light Therapy Psoriasis Treatment?
Good candidate for Light Therapy Psoriasis Treatment:
1. Mild to Moderate Psoriasis: People with mild to moderate psoriasis are generally good candidates for light therapy. This includes people who have psoriasis on less than 10 percent of their body surface area.
2. Those with Stubborn or Resistant Psoriasis: Light therapy can be an effective treatment for people who have stubborn or resistant psoriasis that isn't responding to other treatments.
3. Those who Prefer Non-invasive Treatments: Light therapy is a non-invasive treatment option that may be preferred by people who want to avoid more invasive or systemic treatments.
4. Those without Certain Medical Conditions: People with certain medical conditions, such as lupus or skin cancer, may not be good candidates for light therapy. Additionally, people who are taking certain medications, such as antibiotics or diuretics, may not be able to undergo light therapy.
5. Those who can Commit to Regular Treatments: Light therapy for psoriasis typically requires regular treatments over a period of weeks or months. People who are willing and able to commit to this treatment schedule are good candidates for light therapy.
How often do you need to undergo Light Therapy for Psoriasis?
The frequency of light therapy treatments will depend on the severity of your psoriasis, your skin type, your response, and the type of light therapy being used. Typically, UVB therapy requires three treatments per week initially. Gradually, the frequency may be reduced to twice a week or less, depending on the patient's response and how their skin adapts to the treatment.
PUVA therapy, on the other hand, involves photosensitizing agents, such as psoralen, combined with exposure to UVA light. PUVA treatment often starts with two to three sessions per week, followed by a gradual reduction in frequency as the condition improves. Many patients may ultimately need maintenance sessions every few weeks to manage flare-ups and sustain the therapeutic effect.
It's important to note that the duration of each light therapy session also varies and is determined by your doctor. Sessions can range from a few seconds to several minutes, depending on factors such as the type and intensity of light used, the individual's skin type, and the severity of their psoriasis. Regular monitoring, evaluations, and open communication with your healthcare team are crucial to ensure optimal outcomes and the minimisation of potential side effects associated with light therapy.
