How Does UVB Work for Psoriasis?
Share
Living with psoriasis can be frustrating, especially when flare-ups impact your daily life, confidence, and comfort. Many treatment options exist, but one that consistently shows effectiveness is UVB phototherapy. If you’ve been wondering how does UVB work for psoriasis and whether at-home devices can make a difference, this article breaks it down in simple terms.
At Australian Psoriasis and Eczema Supplies, we specialise in providing clinically proven tools, such as UVB lamps and light therapy devices, so you can manage your condition safely and effectively in the comfort of your home. Let’s explore how UVB works, why it’s trusted by dermatologists worldwide, and how you can use our products to take back control of your skin.
What Is UVB Light?
UVB stands for Ultraviolet B, a specific wavelength of light found naturally in sunlight. Unlike UVA rays, which are more associated with tanning and skin ageing, UVB penetrates the upper layers of the skin, where psoriasis originates.
When used in controlled doses, UVB light has therapeutic effects on psoriasis by slowing down the rapid growth of skin cells that causes plaques, redness, and scaling. Dermatologists have used this treatment for decades, and modern at-home lamps now allow you to achieve the same benefits without visiting a clinic.
How Does UVB Work for Psoriasis?
The key question many people ask is: how does UVB work for psoriasis exactly?
UVB Targets Skin Cell Overgrowth
Psoriasis occurs when your skin cells turn over too quickly—sometimes in just a few days instead of weeks. This creates thick, scaly patches. UVB light penetrates the skin and slows the production of these cells, giving your body time to heal and reduce inflammation.
UVB Reduces Inflammation
Psoriasis isn’t just about cell growth; it’s also an immune system issue. The immune system sends signals that cause inflammation and redness. UVB light helps calm overactive immune responses, which reduces redness and itching.
UVB Improves Visible Symptoms
Over time, consistent UVB treatment leads to noticeable improvements: plaques flatten, redness fades, and itchiness eases. Many users experience clearance or significant reduction in symptoms after just a few weeks of proper use.
Types of UVB Therapy Available
When searching for treatment, you’ll come across two types of UVB therapy: Broadband UVB and Narrowband UVB.
-
Broadband UVB: An older form of therapy that uses the full range of UVB rays. While effective, it’s less precise and may cause more side effects.
-
Narrowband UVB (311nm): The gold standard for psoriasis treatment. It uses a very specific wavelength (311 nanometres) proven to be the most effective for clearing psoriasis while minimising risks.
At Australian Psoriasis and Eczema Supplies, most of our UVB light therapy devices are narrowband 311nm, giving you the safest and most clinically trusted option.
UVB Devices You Can Use at Home
Traditionally, UVB therapy required visiting a hospital or dermatology clinic multiple times per week. For many Australians, this is inconvenient, expensive, and time-consuming. That’s why at-home UVB devices are so valuable.
Here are some of our top solutions available at psoriasisandeczema.com.au:
1. Desktop UVB 311nm Light Therapy Lamp
Perfect for treating larger areas like arms, legs, or torso. It provides even coverage and is easy to use while sitting comfortably at home. Many customers appreciate how quickly symptoms improve when used consistently.
2. Portable 308nm UVB Phototherapy Machine (Targeted)
A compact option ideal for small patches of psoriasis, such as on the scalp, elbows, or knees. Its portability makes it easy to target flare-ups without needing a full-sized lamp.
3. Handheld UVB Phototherapy Comb
Specially designed for scalp psoriasis, this device has a comb attachment that lets the UVB light reach through hair to the affected skin. It’s also effective for smaller, stubborn spots elsewhere on the body.
By offering a range of devices, we ensure there’s an option that fits your lifestyle and psoriasis severity.
Safety of UVB Light Therapy
Understandably, many people worry about safety when using light therapy. Here are some reassuring facts:
-
Narrowband UVB is dermatologist-recommended and backed by decades of clinical studies.
-
Devices are designed to deliver controlled doses, reducing the risk of burns or overexposure.
-
UVB therapy does not use UVA light, which is linked to tanning beds and higher risks of skin damage.
-
When used correctly and under guidance, it is safe for long-term management of psoriasis.
At Australian Psoriasis and Eczema Supplies, every product includes clear instructions, and we provide resources to help you use your device safely and effectively.
Benefits of Using UVB Therapy
Using UVB light therapy at home offers many advantages compared to creams, ointments, or prescription medications:
-
Non-invasive and drug-free – No need to worry about side effects from long-term steroid use.
-
Convenient – Treat psoriasis in your own home, on your own schedule.
-
Cost-effective – A one-time investment saves money compared to ongoing clinic visits.
-
Effective for many people – Research shows 60–70% of psoriasis patients see significant improvement with UVB therapy.
-
Safe for repeated use – Narrowband UVB can be used for flare-ups whenever they occur.
Tips for Getting the Best Results
To make the most of your UVB device, follow these guidelines:
Start Slowly
Begin with short treatment times as directed in your device manual. Overexposure can irritate the skin, so consistency—not intensity—is key.
Protect Unaffected Areas
Cover healthy skin with clothing or sunscreen if you’re only treating specific patches.
Stick to a Routine
Most people see results after 2–3 sessions per week for several weeks. Make UVB therapy part of your regular self-care routine.
Monitor Your Progress
Take photos of your skin before starting, then weekly, so you can see improvements clearly.
Combine with Moisturisers
UVB therapy works best when paired with a gentle, fragrance-free moisturiser to keep skin hydrated and reduce irritation.
