Eczema is a chronic inflammatory skin condition that affects millions of people worldwide, causing itchy, inflamed, and sometimes painful skin. While traditional treatments like topical creams and oral medications are commonly used to manage eczema symptoms, light therapy has emerged as a promising alternative. Here’s a closer look at the pros and cons of eczema light therapy and whether it might be right for you.
The Lowdown on Light Therapy for Eczema
Light therapy, also known as phototherapy or heliotherapy, involves exposing the skin to ultraviolet (UV) light under controlled conditions. It is considered effective for eczema due to its ability to reduce inflammation and itching—two of the hallmark symptoms of the condition.
UV light targets specific immune cells in the skin called T-cells, which are involved in triggering the inflammatory response that leads to eczema flare-ups. By suppressing the activity of these T-cells, light therapy can help calm the skin’s immune response, leading to reduced inflammation and better symptom management.
Light therapy also promotes skin healing and repair. UV light stimulates the production of vitamin D, which is essential for maintaining a healthy skin barrier. Since eczema often disrupts the skin barrier, making it more prone to dryness and irritation, light therapy can help restore its integrity, reduce flare-ups, and promote overall skin health.

Who Is a Fit for Light Therapy’s Perks?
Eczema light therapy is typically recommended for individuals with moderate to severe eczema that hasn’t responded well to other conventional treatments. People with widespread or stubborn patches of eczema—especially those that don’t improve with topical creams or oral medications—may benefit the most from light therapy.
Additionally, light therapy can be especially appealing to those who prefer non-invasive treatments over medications or harsh topical treatments. It’s a targeted approach that doesn’t involve ingesting potent drugs or applying chemicals directly to the skin, making it a safer alternative for those with sensitivities or concerns about side effects from other treatments.
If you’re looking for a drug-free, holistic approach to managing your eczema, light therapy offers a compelling option. It can also be a great choice for people who experience allergic reactions to certain medications or ingredients found in skincare products.
How Light Therapy Works to Help Treat Eczema
Light therapy is a non-invasive treatment that uses specific wavelengths of light to target and treat various skin conditions, including eczema. By delivering UV light to the skin, the therapy reduces inflammation, suppresses the immune system’s response, and promotes skin healing.
There are different types of light therapy commonly used for eczema treatment:
- Narrowband UVB therapy – This treatment emits a specific wavelength of UVB light that targets inflamed skin areas. It is often preferred for localized eczema or psoriasis because it is more targeted and has fewer side effects compared to other forms of phototherapy.
- UVA1 phototherapy – Using longer wavelengths of UVA light, this therapy penetrates deeper into the skin and targets inflammatory cells. UVA1 light therapy can also stimulate cell regeneration and collagen production, helping to strengthen the skin’s protective barrier.
By promoting skin cell renewal and improving the function of the skin barrier, light therapy can enhance the skin’s ability to withstand irritants and allergens, reducing flare-ups and improving overall skin health.

What to Expect at Your Light Therapy Appointment
If you’re considering light therapy for your eczema treatment, here’s what you can expect during your appointment:
- Consultation: The session typically begins with a consultation where your healthcare provider will review your medical history, current eczema treatments, and any medications you’re using. This ensures the treatment plan is tailored to your needs.
- Preparation: Depending on the type of light therapy, you may be asked to undress partially or fully to expose the affected areas of skin. You will also be provided with protective eyewear to shield your eyes from UV exposure.
- Treatment: During the session, you’ll be positioned in front of the light therapy device, where the UV light will be directed at the eczema-affected areas. The length and frequency of each session will depend on the specific therapy used and your skin’s response.
- Post-treatment care: After the session, you may be advised to moisturize your skin and avoid direct sun exposure for a while. It’s important to follow any aftercare instructions to maximize the benefits of the treatment and reduce the risk of side effects.
Possible Disadvantages of Eczema Light Therapy
While light therapy offers numerous benefits, there are potential drawbacks to consider:
- Skin Damage: Excessive or prolonged exposure to UV light can lead to sunburn-like symptoms, such as redness, blistering, and an increased risk of skin cancer. To minimize these risks, it’s important to follow your healthcare provider’s treatment plan strictly.
- Time Commitment: Light therapy typically requires multiple sessions per week for several weeks or months to see significant results. This can be challenging for individuals with busy schedules or limited access to a healthcare facility offering light therapy.
- Side Effects: Some people may experience mild side effects like dryness, redness, or irritation of the skin after a session. These side effects are usually temporary but can affect the quality of life during treatment.
- Cost: If light therapy is not covered by insurance, it may involve additional costs for regular sessions, making it less accessible for some individuals.

Is Light Therapy Right for Your Eczema Treatment Plan?
To determine if light therapy is a suitable option for your eczema, it’s important to consider your eczema severity, skin type, and lifestyle. Light therapy is most effective for people with moderate to severe eczema that hasn’t responded to other treatments. If your eczema is mild or well-managed with topical medications, light therapy may not be necessary.
Your dermatologist can evaluate your skin’s condition, review your medical history, and discuss any contraindications (e.g., photosensitivity disorders) before recommending light therapy. It’s also essential to assess whether you can commit to the time and resources required for regular treatments.
Conclusion
Light therapy for eczema offers a powerful treatment option, especially for those with moderate to severe symptoms that have not responded to traditional treatments. It provides anti-inflammatory effects, supports skin healing, and can reduce the need for medications. However, it’s important to weigh the potential risks, including side effects and the time commitment involved.
Ultimately, light therapy is not a one-size-fits-all solution, and consulting with a dermatologist is key to determining if it’s the right choice for you. By combining light therapy with proper skincare and lifestyle changes, individuals can achieve better control over eczema symptoms and improve their overall quality of life.
