- Marked redness: pause treatment until the skin has returned to normal, then reduce the exposure time by 20%.
- The typical exposure per spot is approximately 3–4 minutes, depending on skin type.
The Philips BU-1S handheld NB-UVB lamp is designed to provide a practical and user-friendly option for home phototherapy for vitiligo, psoriasis and other inflammatory skin conditions. Regular, carefully adjusted treatment can help support gradual improvement over time.

My 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 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.

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.

Vitiligo Treatment
I ordered the phototherapy lamp together with the recommended products, and I have to say it truly exceeded my expectations. A huge advantage is the guidance you receive alongside it – thanks to this, I knew from the very beginning how to combine the lamp and the products properly. With consistent use, following the recommendations and making a few small lifestyle adjustments, you really do start to see results. In my case, pigment has even started to return on the back of my hand – exactly in an area where progress is usually extremely slow. Thank you for the very friendly and supportive service. I would recommend this to anyone dealing with the same condition – sticking with it really pays off.

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.
