Psoriasis is a chronic autoimmune condition that causes skin cells to build up and form itchy, scaly patches. Light therapy is a common treatment option for psoriasis, as it can help to slow down the excessive growth of skin cells. Among various forms of light therapy, two kinds of light therapy frequently used for psoriasis treatment are UVB phototherapy and PUVA therapy. In this discussion, we will explore the differences between UVB phototherapy and PUVA therapy and which might be more suitable for people with different types of psoriasis.

Understanding Psoriasis
Before we dive into the various types of light therapy available for psoriasis, it’s essential first to understand the condition itself. Psoriasis is a chronic autoimmune disease that affects the skin, causing it to become red, itchy, and scaly. It can occur on any part of the body, but it’s most commonly found on the scalp, elbows, knees, and lower back.
Types of Psoriasis
There are several types of psoriasis, each with its unique set of symptoms. The most common types include plaque psoriasis, guttate psoriasis, inverse psoriasis, pustular psoriasis, and erythrodermic psoriasis.
Causes of Psoriasis
While the exact cause of psoriasis is unknown, experts believe it may be due to a combination of genetic and environmental factors. Triggers for psoriasis can include stress, infections, injuries to the skin, and even certain medications.
Light Therapy for Psoriasis
Light therapy, also known as phototherapy, is a non-invasive treatment that uses specific wavelengths of light to treat skin conditions like psoriasis. It works by slowing down the growth of skin cells and reducing inflammation.
Types of Light Therapy
There are several types of light therapy available for psoriasis, including:
- UVB Therapy: This type of light therapy uses ultraviolet B (UVB) light to treat psoriasis. It can be administered in a doctor’s office or at home using a special lamp.
- PUVA Therapy: PUVA therapy combines a medication called psoralen with UVA light to treat psoriasis. This treatment is usually administered in a doctor’s office.
- Excimer Laser Therapy: Excimer laser therapy uses a high-intensity beam of UVB light to treat psoriasis. It’s often used to target small areas of the body.
- Blue Light Therapy: Blue light therapy uses a specific wavelength of blue light to treat psoriasis. It’s often used in combination with topical medications.
Pros and Cons of Light Therapy
Like any treatment, light therapy has its pros and cons. Some of the benefits of light therapy for psoriasis include:
- Non-invasive: Light therapy is a non-invasive treatment that doesn’t require surgery or medication.
- Effective: Light therapy has been shown to be an effective treatment for psoriasis.
- Convenient: Depending on the type of light therapy used, it can be administered at home or in a doctor’s office.
However, there are also some potential downsides to consider, such as:
- Side Effects: Light therapy can cause side effects like redness, itching, and blistering of the skin.
- Time-Consuming: Depending on the type of light therapy used, treatment sessions can take anywhere from a few minutes to an hour or more.
- Cost: While some types of light therapy can be administered at home, others require visits to a doctor’s office, which can be costly.
Choosing the Right Light Therapy
Choosing the right type of light therapy for psoriasis can depend on several factors, including the severity of your condition, the location of the patches, and your personal preferences. It’s important to discuss your options with a dermatologist to determine the best course of treatment for you.
FAQs: What Kind of Light Therapy for Psoriasis?
What is light therapy for psoriasis?
Light therapy for psoriasis is a medical treatment that involves exposing the skin to ultraviolet light in order to treat psoriasis. The light exposure can reduce the inflammation that causes the psoriasis symptoms and can also help to slow the growth of the skin cells that contribute to the condition.
What are the different types of light therapy for psoriasis?
There are three main types of light therapy for psoriasis: UVB, PUVA and excimer laser. UVB therapy involves exposing the skin to ultraviolet B light, while PUVA therapy involves taking a medication that makes the skin more sensitive to ultraviolet A light. Excimer laser therapy uses a concentrated beam of ultraviolet light to target specific psoriasis lesions.
Which type of light therapy is the most effective for psoriasis?
The type of light therapy that is most effective will depend on the individual patient and their particular case of psoriasis. In general, however, studies have shown that all three types of light therapy are effective in reducing psoriasis symptoms.
What are the risks of light therapy for psoriasis?
Like all medical treatments, there are some risks involved with light therapy for psoriasis. The most common side effect is skin irritation, which can lead to redness, itching and burning. There is also a small risk of skin cancers developing as a result of the light exposure, although this risk is generally considered to be very low.
How often do I need to undergo light therapy for psoriasis?
The frequency of light therapy sessions will depend on the individual patient and their particular case of psoriasis. In general, however, patients can expect to undergo several sessions per week for a period of several weeks or months, with most patients experiencing some improvement in their psoriasis symptoms after just a few sessions.
