FAQs
You have questions, we have answers.
How does the BU-1 built-in timer work?
Set the desired treatment time before use. The timer helps control the duration of each session and automatically stops the lamp when the preset time is complete.
What is the difference between BU-1 and BU-1S?
Both models use 311nm narrowband UVB technology. The main difference is that BU-1 includes a timer for easier session control, while BU-1S uses a simpler manual operation without a timer.
How long does phototherapy usually take?
Treatment time varies from person to person and depends on the size, location, and condition of the treated area. Consistent use over several months may be needed before noticeable changes appear.
When can I expect to see initial results?
Changes may gradually appear after several weeks or months of consistent use. The response can vary depending on the treated area and individual skin condition.
Do I need to wear protective goggles during treatment?
Yes. UV-protective goggles should be worn during UVB exposure. Avoid looking directly at the UVB lamp while it is operating.
Can I use the BU-1 during summer?
Yes, but avoid combining excessive sunlight exposure with UVB treatment. If the treated skin becomes sunburned or irritated, allow it to recover before continuing.
What should I do if my skin becomes red after treatment?
Mild redness can occur after UVB exposure. If the skin becomes noticeably red, sore, swollen, or uncomfortable, pause treatment until the reaction has fully settled before continuing.
Why is there no redness after my first treatment?
This can be normal, especially when starting with a short exposure time. Skin response varies between individuals, so treatment time should be adjusted gradually according to professional guidance.
This thing is okay. I haven't tried it again yet, but it seems pretty good.
Thank you 👍 l hope it works.
The seller provided excellent service and patiently explained everything. I've only used the lamp twice so far and am still waiting to see the results. I hope this helps.
I received it quickly. Thank you, seller.
Everything went well with my order. This isn't my first time buying this product, and I've had a good experience with the phototherapy. I would definitely purchase again.
Good product. I got it at a very good price. The lamp works well and I've purchased it before. Thank you to the seller.
Everything went well with my order. I'm glad the lamp arrived safely and without any damage, especially since delivery companies are not always very careful with fragile items.
5 stars. My son had a small vitiligo spot on his foot that we’ve been treating with this home UV unit for 4 months. Happy to report it’s almost gone. We used it every other day, never missed a session, and the pigmentation slowly but surely came back. Super easy to operate, no side effects, and way cheaper than clinic visits. Absolutely worth the money. Highly recommend for anyone dealing with patches.
Everything went well with my order and it arrived safely again. The only downside was that the courier service wasn't very friendly. Other than that, the product works as expected. I've bought it before and had good results with it.
Everything works fine and it arrived on time.
The device arrived in good condition and looks exactly as shown on the website. The instructions are clear and easy to understand. I'm still in the early stages of using it and evaluating the quality and results. My doctor has also seen it and was positive about the device. Very good service, thank you.
Fifteen treatments in, and we're seeing real signs of repigmentation on my child's skin—what a relief! The at‑home device is so much easier than going to a clinic, and my son/daughter doesn't mind it at all. I'm really happy with how things are going and don't regret the investment one bit.
Good!
It works well overall. The only thing I've noticed is that if the lamp stays on for a long time, it may automatically shut off because of overheating. You need to wait for it to cool down before using it again.
Highly recommend this seller!
Shipping from the seller was 10/10, but the delivery service was 0/10. I wasn't satisfied with MailAmericas.
The item is in good condition..very recommended ... thank you seller
Early results with the BU-1 UVB unit are excellent. After years of pompholyx eczema requiring steroids and antibiotics, I'm now free of redness and itch. Flare-ups used to come every two months; right now my skin is the clearest it's been in years. Well-built, clear instructions, handy timer. Pricey, but the outcome justifies the cost.
One month in, after 15 sessions with our 9‑year‑old, we're already seeing pigment returning to his vitiligo patches. The device fits easily into our daily routine and saves clinic trips. So far, both the results and the purchase feel completely worthwhile.
Have not tried the light therapy yet hoping it helps my daughter psoriasis
Works as expected. It took about 15 days to arrive.
Worked quick!
I am so pleased with the results to treat my psoriasis. It's been 4 weeks and it has improved all areas, even fully clearing some.
The device arrived, but I couldn't really understand the certification information for the lamp in the documents. Other than that, everything seems fine so far.
