Light Eczema Treatment

At Zemel Dermatology, we understand how challenging it can be to manage eczema, especially when standard treatments no longer provide relief. That’s why we offer advanced light therapy (phototherapy) as a safe, effective solution for moderate to severe eczema. This non-invasive treatment uses controlled doses of ultraviolet (UV) light to reduce inflammation, soothe itching, and promote healthier skin over time. Ideal for patients seeking alternatives to topical steroids or systemic medications, our light eczema treatment is customized to match your skin type and condition severity. 

Backed by clinical expertise and modern technology, Zemel Dermatology is committed to helping you achieve long-lasting skin comfort and improved quality of life through targeted, professional care.

How Phototherapy Works to Reduce Eczema Symptoms

Eczema flare-up

Suppression of Immune Response

Eczema (atopic dermatitis) is driven by an overactive immune response in the skin, resulting in chronic inflammation, redness, itching, and barrier disruption. Phototherapy, particularly narrowband UVB, helps by dampening this immune activity. The UVB light downregulates pro-inflammatory cytokines (such as interleukins and tumor necrosis factor-alpha) and reduces the numbers and activity of T‑cells in the skin. This immune moderation leads to less inflammation, fewer flare-ups, and calmer skin overall.

Enhancement of Skin Barrier Function

One of the core problems in eczema is a weak skin barrier, which allows irritants, allergens, and microbes to penetrate easily. Phototherapy stimulates the production and maturation of keratinocyte cells that form the outermost layer of the skin. This results in more robust production of ceramides and lipids, key components of a healthy barrier. Strengthening this barrier helps reduce water loss and protects against external triggers, easing dryness and irritation.

Reduction of Microbial Colonisation

Many individuals with eczema have higher levels of Staphylococcus aureus on their skin, which can worsen inflammation and infection risk. UVB phototherapy helps lower these bacterial numbers, either directly through antimicrobial effects or indirectly by restoring barrier function and reducing inflammation. The result is fewer infections and a calmer, healthier skin ecosystem.

Decreased Itch and Hyperplasia

Chronic eczema leads to thickened (hyperplastic) skin and persistent itchiness. Phototherapy interrupts this process by regulating skin cell turnover and reducing nerve sensitivity. Over time, treated skin becomes thinner and more normal in texture, and the intense urge to scratch diminishes significantly.

Stimulating Repair and Healing

UVB light induces certain skin repair mechanisms, including DNA repair pathways and antioxidant responses. While UV can cause damage in high doses, narrowband UVB is designed to maximize therapeutic benefits while minimizing harm. These repair processes help the skin recover from past damage faster and more effectively.

What to Expect During and After Phototherapy Treatment Sessions

FAQ’s

What is light therapy for eczema, and how does it work?

Light therapy, or phototherapy, treats eczema using controlled ultraviolet (UV) light, especially narrowband UVB. It slows skin cell growth and reduces inflammation, easing itching and redness.

Light therapy is most effective for conditions like atopic dermatitis, nummular eczema, and chronic hand eczema. Its success can vary based on the type and severity of eczema, as well as individual response. During your consultation, we’ll carefully assess your condition to determine if phototherapy is the right treatment for you.

Yes, phototherapy is considered safe for children when supervised by a dermatologist. It’s used for moderate to severe eczema unresponsive to topical treatments. Sessions are shorter and adjusted for age and skin type. It’s non-invasive, and children usually tolerate it well with minimal discomfort or risk.
Phototherapy offers an alternative to topical steroids and oral medications, especially for persistent eczema. It reduces inflammation without systemic side effects. However, it requires frequent clinic visits, which may be inconvenient. It’s often used when creams fail, but before moving to stronger systemic treatments like immunosuppressants.
Yes, light therapy is often used alongside topical steroids, moisturizers, or non-steroid creams to enhance results. However, combining it with certain systemic treatments may increase risks. That’s why we advise coordinating with our professional team to create a safe, effective treatment plan.
You may be a good candidate if you have moderate to severe eczema that hasn’t responded to creams or ointments. It’s also ideal if you prefer drug-free options and can attend multiple weekly sessions.
