How Long Does Light Therapy Take to Work for Psoriasis?

Living with psoriasis can feel overwhelming, especially when flare-ups affect your skin, confidence, and overall comfort. Many people explore different treatment options, but one therapy that continues to stand out for its effectiveness is light therapy. At Australian Psoriasis and Eczema Supplies, we provide a range of UVB 311nm light therapy lamps designed to support people managing psoriasis from the comfort of home. If you’re considering this option, you may be asking: how long does light therapy take to work for psoriasis?

Let’s explore the answer in detail, while also breaking down what to expect and how to get the best results.

What Is Light Therapy for Psoriasis?

Light therapy, also known as phototherapy, uses controlled doses of UVB light to treat psoriasis. Unlike natural sunlight, which exposes skin to both UVA and UVB rays, medical-grade UVB lamps provide a narrowband wavelength (311nm) proven to reduce inflammation, slow skin cell overgrowth, and promote healing.

Our range of desktop UVB lamps and handheld light therapy devices allow individuals to receive dermatologist-endorsed treatment at home, without the need for frequent clinic visits.

How Long Before You See Results?

One of the most common questions people ask is: how long does light therapy take to work for psoriasis?

While results vary between individuals, most people begin to notice improvements within 2 to 4 weeks of consistent use. Early signs may include:

  • Reduced redness and itching

  • Thinner, less scaly patches

  • Shorter flare-up duration

For more significant clearance, it usually takes 6 to 8 weeks of regular treatment sessions. With ongoing use, many people experience smoother, calmer skin and longer remission periods between flare-ups.

Factors That Affect Treatment Time

Not everyone responds to light therapy in the same way. Several factors can influence how quickly you see results:

1. Severity of Psoriasis

Mild plaque psoriasis may improve more quickly compared to widespread or stubborn patches.

2. Consistency of Use

Most treatment schedules recommend 3 to 5 sessions per week, with gradual increases in exposure time. Skipping sessions can slow down results.

3. Skin Type

Fairer skin may respond faster to UVB treatment, while darker skin tones may need slightly longer to see noticeable improvements.

4. Correct Device and Setup

Using a medical-grade narrowband UVB lamp ensures the right wavelength is delivered safely and effectively. At Australian Psoriasis and Eczema Supplies, all our lamps are designed specifically for psoriasis and eczema.

Why Light Therapy Is Worth the Wait

Unlike creams or medications that may only provide short-term relief, light therapy works by addressing psoriasis at a cellular level. It slows down the rapid turnover of skin cells, reduces inflammation, and promotes natural healing.

While patience is required—since results aren’t instant—the long-term benefits are well worth the wait. Many customers report:

  • Long-lasting clearance of plaques

  • Fewer flare-ups over time

  • Reduced reliance on steroid creams

Tips to Maximise Results from Light Therapy

Getting the most out of your light therapy routine requires more than just switching on the lamp. Here are some tips to help you achieve the best outcomes:

Stay Consistent

Create a schedule and stick to it. Regular exposure is key for results.

Follow Instructions

Always begin with short treatment times and gradually increase exposure as recommended.

Protect Healthy Skin

Cover unaffected areas when necessary to avoid unnecessary exposure.

Combine with Other Care

Moisturising regularly can improve results, as hydrated skin responds better to UVB therapy. Explore our soothing skincare range including Aveeno Soothing Bath Soak to keep skin calm and nourished.

Safety Considerations

When used correctly, narrowband UVB light therapy is safe and effective. However, it’s important to keep the following in mind:

  • Always follow the manufacturer’s guidelines

  • Do not exceed recommended session times

  • Consult your healthcare professional before starting if you have other medical conditions

Our products are designed with safety in mind, giving you dermatologist-quality treatment from home without the risks of unfiltered sunlight or tanning beds.

Realistic Expectations

So, how long does light therapy take to work for psoriasis? In most cases, noticeable improvement begins within 2–4 weeks, with more significant results in 6–8 weeks. For some, clearance may take longer depending on skin type, psoriasis severity, and treatment adherence.

Patience and consistency are essential. While it may not be an overnight fix, light therapy can be one of the most effective long-term management tools for psoriasis, helping you regain control and improve quality of life.
