Light Therapy for Eczema: What to Know Before You Start
Light therapy for eczema uses controlled UVB light to help manage inflammation and flare-ups as part of a broader eczema management routine — typically alongside topical treatments, not instead of them.
At a glance:
- Uses narrowband UVB (311nm) wavelength
- Available as home-use devices or in-clinic phototherapy
- Requires GP or dermatologist guidance before starting
- Often used alongside topical treatments, not as a standalone fix
What Is Light Therapy for Eczema?
Light therapy, also known as phototherapy, uses specific wavelengths of UV light and is one approach some people use alongside other eczema management strategies. DermNet NZ notes that narrowband UVB phototherapy is commonly used for inflammatory skin conditions, with shorter exposure times and longer periods of remission compared to broadband UVB.
Australian Psoriasis and Eczema Supplies offers UVB 311nm light therapy lamps designed for home use, giving Australians the option to manage sessions without the ongoing logistics of frequent clinic attendance.
How Light Therapy May Help with Eczema Symptoms
Regular UVB sessions are sometimes associated with:
- Reduced itching and redness — UVB exposure is understood to affect inflammatory activity in the skin
- Slower skin cell turnover — potentially helping with the dry, scaly patches common in eczema
- Vitamin D production — a secondary effect of UVB exposure
- Reduced reliance on topical steroids for some people, as part of a broader routine

How People Commonly Use Light Therapy at Home
Rather than a fixed usage protocol, session length, frequency, and distance from the device should be set with guidance from your GP or dermatologist, who can account for your skin type, condition severity, and treatment history. Protective eyewear should always be worn during sessions, and any usage plan should follow professional guidance rather than general product information.
The key point: this is adjustable equipment, not a self-directed treatment schedule — your GP or dermatologist sets the plan.
Who Commonly Considers Light Therapy for Eczema
Light therapy is often considered by:
- Adults and children with chronic eczema or atopic dermatitis, under medical guidance
- People who haven't had the results they wanted from topical creams alone
- People looking for a non-topical option to discuss with their treating specialist
- People with widespread eczema that's difficult to manage with creams alone
Who May Prefer a Different Approach
Light therapy isn't the right fit for everyone. You may want to discuss other options with your GP or dermatologist if you:
- Have a photosensitivity condition or are on photosensitising medication
- Prefer to explore topical-only management first
- Have very limited, small-area eczema where creams alone may be sufficient
How Home Light Therapy Compares to Clinic Phototherapy
| Feature | Clinic Phototherapy | At-Home UVB Lamp |
|---|---|---|
| Convenience | Requires appointments | Use at home on your own schedule |
| Cost structure | Ongoing session fees | One-time device cost |
| Supervision | Direct clinical supervision each session | Requires GP/dermatologist-set plan, used independently |
| Setting | Clinical setting | Private home setting |
Both approaches require medical guidance to set an appropriate plan — the difference is where the sessions take place, not whether professional input is needed.
Safety Considerations for Light Therapy at Home
- Always follow the exposure plan set by your GP or dermatologist — never exceed it
- Always wear the protective eyewear provided
- Do not combine with other light-based treatments unless advised by your treating specialist
- Avoid use during photosensitising medication courses unless cleared by your doctor
- Healthdirect Australia recommends discussing phototherapy with a GP or dermatologist before starting, particularly for those with existing skin conditions or on photosensitising medications
Common Mistakes People Make
Starting sessions without professional guidance on dosing. Treating light therapy as a replacement for topical care rather than a complement to it. Skipping protective eyewear. Ignoring photosensitising medication interactions.
Frequently Asked Questions
What is light therapy for eczema? A form of phototherapy using narrowband UVB light, used by some people as part of a broader eczema management plan alongside topical treatments.
Is narrowband UVB the same for eczema and psoriasis? The wavelength (311nm) is the same, though the appropriate plan for each condition should be set individually with your dermatologist.
Can I use light therapy instead of my current eczema creams? This is a decision for your GP or dermatologist — light therapy is generally used alongside other management strategies, not necessarily as a replacement.
What should I check before starting? Confirm with your GP or dermatologist that phototherapy suits your specific skin condition, current medications, and treatment history.
