Red Light Therapy for Psoriasis: A New Way to Soothe Your Skin

Living with psoriasis can be painful, itchy, and emotionally exhausting. Red light therapy for psoriasis is one non-invasive, drug-free approach some Australians research as part of managing symptoms, and understanding how it works — and what it can realistically offer — matters before deciding whether to try it.

At a glance:

• Red light therapy uses wavelengths around 630–660nm, working differently from UVB
• Understood to affect inflammation and support skin cell processes
• Available as handheld devices, face masks, and scalp-specific formats
• Any usage plan should be set by your GP or dermatologist

What Is Red Light Therapy?

Red light therapy (RLT) is a form of phototherapy using red and near-infrared wavelengths, understood to work differently from UVB — targeting inflammation and cellular processes rather than slowing skin cell growth directly. Red light devices typically emit light between 630nm and 660nm. DermNet NZ lists various phototherapy approaches used in dermatology, though the evidence base for red light in psoriasis specifically is less extensive than for narrowband UVB.

In short: red light and UVB work through different mechanisms — one isn't simply a gentler version of the other.

How Red Light Therapy Is Understood to Help Psoriasis

Some mechanisms commonly discussed include affecting overactive immune responses linked to inflammation, supporting normal cell turnover through increased blood flow, and potentially supporting skin barrier function. Some people report reduced itching and sensitivity with consistent use, though individual responses vary considerably and results aren't guaranteed.

Red Light Therapy vs UVB Therapy

Both approaches are used by some people for psoriasis, but they work differently and have different levels of evidence specifically for this condition. Some people discuss combining both under professional guidance — for example, using a Desktop UVB 311nm Light Therapy Lamp alongside a red light device, though any combination should be confirmed with a dermatologist first. Our red light vs UVB comparison covers this distinction in more detail.

In short: red light and UVB aren't competing for the same job — understanding which mechanism is relevant to your presentation matters more than picking a side.

Who Commonly Considers Red Light Therapy

People looking for a non-topical, drug-free approach to discuss with their treating specialist, and people who've tried topical creams without the relief they wanted. Our guide on phototherapy for psoriasis and eczema covers the broader range of light-based approaches.

Who May Prefer a Different Approach

You may want to discuss other options with your GP or dermatologist if you:

• Have open wounds or active infections in the area
• Have significant or widespread plaque involvement, where your dermatologist may recommend an approach with a more established evidence base
• Are taking photosensitising medication

How to Use Red Light Therapy for Psoriasis at Home

Rather than a fixed protocol, session length, frequency, and progression should be set by your GP or dermatologist based on your skin type and condition. General points that typically apply, though specifics come from your treating specialist:

• Cleanse the affected area beforehand, free from creams or lotions that might block light absorption
• Follow the distance and positioning guidance provided with your specific device
• Begin conservatively and increase only as your specialist advises
• Track your sessions and any changes to discuss at follow-ups
• Always use the protective eyewear provided, and avoid direct eye exposure

The key point: consistency under a specialist-set plan matters more than following a generic online schedule.

Safety Considerations

Red light therapy is generally considered gentle and non-invasive. Avoid direct eye exposure and use protective goggles. Don't use over open wounds or active infections. Consult your dermatologist before combining red light with other treatments.

Common Mistakes People Make

Expecting a fixed timeframe for results rather than understanding individual variation. Following a generic session schedule instead of a plan set by a GP or dermatologist. Reducing or stopping other treatments, like steroid creams, without discussing this with a dermatologist first. Assuming red light and UVB are interchangeable, when they work through different mechanisms.

Frequently Asked Questions

Is red light therapy effective for psoriasis? Some mechanisms are relevant to psoriasis, but the evidence base is less extensive than for UVB specifically. Individual responses vary, and results aren't guaranteed.

How long does it take to see results? This varies significantly by individual and severity — your GP or dermatologist can give you a realistic estimate for your specific situation rather than a general timeframe.

Can I combine red light therapy with UVB? This is worth discussing with your dermatologist, who can advise on whether combining approaches suits your specific situation.

Is red light therapy safe to use at home? Generally considered gentle when used correctly, with protective eyewear and following device guidance, though any usage plan should be confirmed with your GP or dermatologist.

Red Light Therapy for Psoriasis: Bringing It Together

Red light therapy for psoriasis is one approach some Australians research as part of managing symptoms, working through a different mechanism than UVB and with a less extensive evidence base specifically for this condition. Explore the light therapy range at Australian Psoriasis and Eczema Supplies, and speak with your GP or dermatologist to confirm what's appropriate for your skin condition, current medications, and medical history.
