Only treat when any redness (erythema) from the previous session has subsided and the skin has fully recovered.

A skin reaction (erythema - redness) typically appears 6–8 hours after exposure:

No redness: increase exposure time by 20 seconds at the next session.
Mild redness: if it clears within 24 hours, extend by 20 seconds at the next session.
Noticeable redness (desired state): if it is still pink after 24 hours, keep the same time and wait for it to fully fade.
Marked redness: pause treatment until the skin returns to normal, then reduce the time by 20%.
The typical exposure per spot is about 3–4 minutes, depending on skin type.

The Philips BU-1S handheld NB-UVB lamp for vitiligo & psoriasis treatment is designed to be user-friendly, versatile and highly effective for managing vitiligo, psoriasis and other inflammatory skin conditions. With regular, well-titrated use, you can support healthier, more even skin.

Frequently Asked Questions – Philips BU‑1S for psoriasis

Is the Philips BU‑1S UVB lamp suitable for scalp psoriasis treatment? ▼

Yes. The Philips BU‑1S includes a comb attachment that helps to part the hair and bring the 311 nm NB‑UVB light closer to the scalp. Treat small areas at a time, always wear the supplied UV‑protective goggles and avoid shining the light into the eyes or on mucous membranes.

How often can I use 311 nm UVB for psoriasis at home? ▼

In most cases, psoriasis is treated 2–3 times per week with at least one rest day between sessions. Do not treat the same area more than once per day. Only increase the exposure time when any redness from the previous session has completely settled.

Can I combine this lamp with topical psoriasis creams? ▼

Many patients use NB‑UVB together with topical treatments such as emollients and prescribed creams. Neutral moisturisers can usually be applied after each session once the skin has cooled down. Some active ingredients (for example strong corticosteroids, retinoids, salicylic acid or tar preparations) may increase photosensitivity. Always follow the advice of your dermatologist or the product leaflet on how to combine them with UVB treatment.

How long does it usually take to see improvement in psoriasis? ▼

Psoriasis is a chronic condition and it typically takes several weeks of regular treatment to notice changes. Many patients start to see smoother, less red plaques after about 4–8 weeks of consistent NB‑UVB therapy, in some cases it can take longer. Results vary between individuals.

Frequently Asked Questions – Philips BU‑1S for vitiligo

Is the Philips BU‑1S suitable for vitiligo? ▼

Yes. The Philips BU‑1S handheld lamp uses 311 nm narrowband UVB, which is the standard wavelength used in many dermatology clinics for vitiligo phototherapy. It is designed for treating small to medium sized patches on the face, hands and body.

How often should I use 311 nm UVB for vitiligo? ▼

In most vitiligo protocols, NB‑UVB is used 2–3 times per week, with at least one complete rest day between sessions. Do not treat the same area more than once per day. Increase the exposure time only when the skin has fully recovered and there is no persistent redness from the previous session.

How long does it take to see repigmentation in vitiligo? ▼

Repigmentation in vitiligo is usually gradual. Many patients need at least 2–3 months of regular NB‑UVB treatment to see the first small freckles of pigment, and meaningful improvement often takes 6–12 months. Areas like the face and neck tend to respond better than hands and feet. Results vary from person to person, so it is important to be patient and continue treatment as advised.

Can I combine the BU‑1S with topical creams for vitiligo? ▼

Yes, NB‑UVB is often combined with topical therapies such as calcineurin inhibitors or creams prescribed by a dermatologist. In many protocols, the cream is applied after the UVB session on cooled, dry skin. Because some products can increase photosensitivity, always follow the specific instructions of your dermatologist or the product leaflet when using them together with UVB light.

I’ve had psoriasis for many years and honestly, looking back, I’m quite surprised that no dermatologist ever recommended UVB light therapy to me. After just two months, my results are better than ever before!!!! The only small downside is that the website is mainly focused on vitiligo – without a friend’s recommendation, I probably would never have found the Philips lamp. If I can suggest, maybe you could improve the website a bit in this way. Still, thank you very much.

vitiligo lamp

I ordered the phototherapy lamp together with the recommended products and I have to say it really exceeded my expectations. A big advantage is also the protocol and advice from Peter that you get with it – thanks to that I knew from the beginning how to properly combine the UVB lamp and Vitistop products. With regular use and following the recommendations, and making a few small lifestyle changes, the results really start to come. In my case, pigment even started to come back on my hands – exactly in the area where it never worked before. Thank you for the very kind and helpful approach and support. I recommend it to anyone dealing with the same problem – sticking with it really pays off.

UVB lamp - psoriasis

We use the UVB lamp for my husband’s psoriasis on the soles of his feet, alongside a psoriasis cream. At the beginning, we treated the areas twice a day, and after three weeks the patches had completely disappeared. For maintenance, we now use the lamp only three times a week. We are very happy with the lamp.

UVB Lamp Philips – Psoriasis

I’ve had scalp problems since my teenage years (around the age of 17). For a long time, I thought it was “just” seborrhoeic dermatitis, and to be honest, I didn’t visit a dermatologist regularly. A few years ago, psoriasis was mentioned for the first time, and more recently it was confirmed – also in connection with my arthritis. UVB therapy was recommended to me, and I noticed an improvement quite quickly: less itching and fewer new plaques. That’s why I decided to order the lamp for home use. From my side, a clear recommendation for psoriasis – I will definitely share my experience with others.

I've been using the Philips UVB lamp for my psoriasis treatment over the past few weeks. It has noticeably reduced my symptoms, and I'll certainly continue with the treatment.

Andrea

Hello, I began UVB cabin treatments in December and decided to take the process more seriously by following the Vitiligoshop 90-day programme. It gave me a clear structure and helped me stay consistent throughout the treatment.

Sophie

Hello everyone, it’s been a while, but I wanted to come back and share an update. My journey with vitiligo began ten months ago.

Julia

My vitiligo appeared about ten years ago as a single small patch on my arm. Slowly, year after year, it spread further — until my hands were completely white and much of my arms were affected too.

Jane V.

Vitiligo first appeared on both of my hands ten years ago. I initially tried to manage it with light therapy, but unfortunately, I didn’t see any results. The treatments were also very time-consuming, and over time, I eventually gave up.

Helen

I have had vitiligo since I was 14. Over the years, the spots slowly became larger and continued to spread. Two years ago, I decided to take a more active approach — I started doing regular sports and made meaningful changes to my diet.

Charlotte

Hello, I’d like to share my story and my results after a year of treatment. My vitiligo first appeared 4–5 years ago, beginning quietly with a few small spots on my face. Since I didn’t know what it was at the time, I chose not to address it initially.

Daniel H.

Hi, I’d like to share an update on my vitiligo repigmentation progress. These photos were taken after three months of using Vitistop Gel, and I’m happy to say that I can already see a noticeable improvement (as shown in the second photo).

Andrew S.

Hello! I’d like to share my latest repigmentation results on my leg and elbow. The new pigment started to appear about three weeks after my seaside treatment.
