Can phototherapy help with psoriasis?

Introduction to Psoriasis and Phototherapy

Psoriasis is a chronic skin condition that affects many individuals in the UK, causing red, scaly patches that can be itchy and painful. Managing psoriasis can be challenging, with various treatments available to alleviate the symptoms. One such treatment is phototherapy, which has been increasingly recognised for its effectiveness in managing psoriasis symptoms.

What is Phototherapy?

Phototherapy, or light therapy, involves exposing the skin to ultraviolet (UV) light under controlled conditions. The most common forms of phototherapy for psoriasis are narrowband UVB, broadband UVB, and PUVA (psoralen combined with UVA light). The type of phototherapy used depends on the severity of the psoriasis and how the patient responds to each type.

How Does Phototherapy Work?

Phototherapy helps to slow down the rapid growth of skin cells, which is characteristic of psoriasis. UVB light penetrates the skin and reduces the proliferation of skin cells, while also having anti-inflammatory effects that can help to reduce plaques. PUVA therapy combines UVA light with a drug called psoralen, which makes the skin more responsive to the UVA light, enhancing the treatment's effectiveness.

Effectiveness of Phototherapy for Psoriasis

Studies have shown that phototherapy can significantly improve symptoms for many people with psoriasis. It is particularly effective for plaque psoriasis, the most common form. Narrowband UVB phototherapy is often preferred because it uses a specific wavelength of light that has been found to be more effective and to have fewer side effects than broadband UVB phototherapy. Regular sessions over a period of weeks are generally necessary to achieve and maintain results.

Considerations and Side Effects

While phototherapy can be effective, it is not suitable for everyone. Patients need to commit to regular sessions, usually several times a week, and it can be time-consuming. Some people may also experience side effects, such as redness and itching, after treatment. Long-term exposure to UV light can increase the risk of skin aging and skin cancer, so it’s important to monitor skin thoroughly and follow the advice of a healthcare professional.

Conclusion

For those managing psoriasis in the UK, phototherapy presents a viable treatment option that can bring significant relief to many sufferers. By consulting with dermatologists and healthcare professionals, patients can determine if phototherapy is the right choice for their condition. It is essential to weigh the benefits against the possible side effects and to ensure the treatment is conducted in a controlled and professional setting to ensure safety and effectiveness.
