Phototherapy, a treatment option that employs ultraviolet (UV) light to manage skin conditions, has emerged as a vital strategy for treating eczema and dermatitis. Eczema, characterized by itchy, inflamed skin, can significantly impact the quality of life, leading to discomfort and emotional stress. Dermatitis refers to inflammation of the skin, often resulting in redness, swelling, and rashes. This document delves into the mechanisms of phototherapy, its benefits, protocols, and common FAQs to assist individuals seeking relief from these conditions.
Phototherapy utilizes specific wavelengths of light to penetrate the skin, targeting affected areas to reduce inflammation and alleviate symptoms. The most common types of phototherapy for eczema and dermatitis include:
Ultraviolet B (UVB) Therapy: This involves exposure to UVB light, which has been shown to effectively reduce symptoms by targeting the immune response that causes skin inflammation. Typically administered in clinics, patients may undergo treatment two to three times per week.
Narrowband UVB: A more recent advancement in UVB therapy, narrowband UVB treatment uses a specific range of wavelengths that provide effective results with fewer side effects. It has become a preferred option for many dermatologists.
Psoralen and Ultraviolet A (PUVA): This combined therapy involves taking a medication called psoralen, which makes the skin more sensitive to UVA light. It is usually reserved for more severe cases of eczema or dermatitis, as it can be more intense than UVB treatment.
Excimer Laser: For localized treatment, excimer lasers deliver UVB light specifically to affected areas, offering a targeted approach to managing symptoms.
The benefits of phototherapy for eczema and dermatitis include:
Reduced Inflammation: Phototherapy works by suppressing the immune response responsible for skin inflammation, leading to decreased redness and irritation.
Decreased Itchiness: By alleviating the underlying inflammation, patients often experience significantly reduced itchiness, improving overall comfort.
Customizable Treatment: Depending on the severity and extent of the condition, dermatologists can tailor phototherapy protocols to meet individual patient needs.
Fewer Side Effects: When compared to systemic medications, phototherapy has a lower risk of side effects, making it a safer long-term option for many patients.
Convenient Sessions: Treatments are often quick, with sessions lasting only 10-30 minutes, allowing patients to integrate them into their routine with relative ease.
When considering phototherapy, it is vital to consult with a qualified dermatologist. The following factors will influence treatment protocols:
Severity of Condition: More severe cases may require more frequent treatments or different types of phototherapy.
Skin Type: Individual responses to light therapy can vary based on skin type and sensitivities, which may influence treatment plans.
Home Phototherapy Options: For some patients, doctors may recommend home devices to facilitate ongoing treatment between in-clinic sessions. These devices must be used correctly to ensure safety and effectiveness.
Bundling with Other Treatments: Phototherapy can be combined with topical treatments or systemic medications for enhanced results, tailored based on patient needs.
Phototherapy for Eczema & Dermatitis
UVTREAT has a state-of-the-art onsite phototherapy centers that offers full-body treatment in as little as 5 to 10 minutes. This painless treatment uses ultraviolet (UV) light—the same type of light found in natural sunlight—that has been specially filtered to remove light wavelengths that are more damaging to the skin.
Exposure to these altered UV rays, called narrow band UVB rays, may shut down the immune system cells in the skin that have caused the inflammation. Phototherapy may relieve symptoms of eczema and dermatitis without the need for medicated skin creams or medications taken by mouth. Phototherapy poses minimal risk of skin cancer and may be safe for children and pregnant women.
Each phototherapy unit is a chamber lined with long, tubular UVB light bulbs. These bulbs emit therapeutic light rays, and the effects of therapy may be noticeable after just a few weeks of treatment. Your dermatologist may suggest medication in addition to phototherapy to enhance the results of both types of treatment.
For people with moderate-to-severe eczema or dermatitis, dermatologists may recommend two or three phototherapy sessions a week. Our dermatologists and staff offer appointments throughout the week, including evenings and Saturdays, to make scheduling treatments convenient for you. Possible side effects include redness, burning, or stinging of the skin, although research shows that side effects to phototherapy are infrequent and usually go away quickly.

Conclusion
Phototherapy presents a promising option for those suffering from eczema and dermatitis, offering effective relief while minimizing potential side effects. By understanding the various types of phototherapy available, alongside their benefits and protocols, patients can make informed decisions about their treatment plans.
Consultation with a healthcare professional is essential to tailor an approach that best meets individual needs and goals. With ongoing advances in phototherapy, there is hope for enhanced management and improvement of symptoms for those affected by these skin conditions.
During a phototherapy session, you will be asked to undress the affected areas, and the dermatologist will expose your skin to UV light from either a lamp or laser device. Protective eyewear will be provided, and the procedure typically lasts a few minutes depending on the extent of the treatment area.
The number of sessions varies from person to person. Generally, patients may require two to three sessions per week, with improvements observed after several weeks of consistent treatment. Your dermatologist will be able to provide a more specific estimate based on your individual condition.
While phototherapy is generally safe, some patients may experience mild side effects such as skin redness, dryness, or peeling in the treated areas. These effects usually resolve quickly. Long-term use carries a slight risk of skin cancer, so ongoing monitoring by a dermatologist is essential.
Most individuals with eczema or dermatitis can benefit from phototherapy; however, certain conditions or medications that increase sensitivity to light may contraindicate its use. It is crucial to discuss your full medical history with your dermatologist before beginning treatment.
Phototherapy is often more effective for moderate to severe eczema and dermatitis, especially when topical treatments fail to provide relief. It targets deeper skin layers and broader areas, whereas topical treatments are more localized.
Many insurance plans include coverage for phototherapy, but it can vary by provider and plan specifics. It’s advisable to verify coverage details with your insurance company prior to commencing treatment.
Preparing for your phototherapy session typically involves avoiding sun exposure and certain medications that can increase skin sensitivity for at least a day before treatment. Follow your dermatologist's specific instructions thoroughly.
Patients may experience improvements in symptoms shortly after treatment, but it may take several weeks to notice substantial results. Proper post-session care is crucial, including keeping the skin moisturized and protecting it from the sun.
