I didn’t notice much at first, but after six weeks, my eczema is much less irritated, and the itching has gone down. This lamp does work!!!
Before using this lamp, my psoriasis would get inflamed when I worked out. The sweat made it worse. Since starting UVB therapy, my skin doesn’t react as badly to exercise anymore, and I feel way more comfortable in the gym.
The lamp works really well for my vitiligo, and I’ve already noticed some repigmentation starting after a couple of months. My only complaint is that the cord is a bit short, which makes it hard to reach certain areas comfortably.
so good!
I hated how people would stare at my psoriasis in public, especially in the summer. This lamp has cleared my skin enough that I don’t feel self-conscious anymore. It’s a small thing, but it is making a big difference
I travel a lot for work, and this lamp is small enough to pack easily. It’s been a lifesaver for keeping my eczema under control on the road.
My dermatologist recommended UV therapy, however he noted that I can buy a portable lamp for home use. I have made a research and found this one. I was not sure which model I should get so I decided to start with the least expensive. I have been in contact with my doctor and customer support from this store. Together we have created a perfect protocol for me to follow. It’s not a miracle overnight fix, but if you use it consistently, it does the job. Make sure to follow the time recommendations! I did and right now I am really really happy with the results!
I started using this lamp for vitiligo on my face and hands. At first, I didn’t see much change. I even talked with customer support about returning, but I was assured that I will see results. I trusted them and after about six-eight weeks, I noticed tiny spots of pigment returning. I was so surprised and happy. As I understood, the key is consistency. I use it 3 times a week, and I’m seeing slow but steady improvement. It’s not an overnight miracle, but after sticking with it, I see results! The build quality is great, and I like that it’s corded — no worrying about batteries dying mid-session
This lamp is super convenient. I was worried about it being corded, but the length is just right. I like that I can treat small areas without having to expose my whole body to UVB, my psoriasis is not too big so fortunately size of a lamp was perfect for me. After a few months of use, my psoriasis is way more manageable and I only doing this once a week!
I’ve had vitiligo for years, and this lamp is helping my skin repigment in some areas. It takes time, but I’m seeing progress on my hands and face. If you have patience and follow a proper schedule, this lamp is a great investment
Every winter, my psoriasis gets worse, but using this lamp helped prevent the usual flare-ups
I have vitiligo on my hands and around my mouth. My doctor told me UVB therapy is one of the only treatments that might help repigment my skin. I’ve been using this lamp 3x a week for three months, and I’m starting to see small pigment spots returning. It’s slow progress, but it’s happening. If you’re treating vitiligo, just know that it takes months, not weeks, to see results.
I hesitated to buy this because of the price, but after seeing my psoriasis clear up by over 50% in two months, I can confidently say it’s worth every penny.
I was convinced UVB therapy at home wouldn’t be as good as the dermatologist’s office, but this lamp changed my mind. It’s not instant, but the results are real.
I don’t think this is a miracle cure, but it definitely helps keep my psoriasis under control. It’s been a useful tool for managing symptoms without relying on as many steroid creams.
I was prescribed in-office phototherapy for my eczema, but the cost and time commitment were overwhelming. After some research, I found this lamp, and it works just like the ones at the clinic! I follow the same exposure time my doctor advised, and within a few weeks, my skin looked SO much better.
I mostly use it on my arms and hands, where my eczema is the worst. My skin isn’t perfect yet, but the dryness and redness have improved a LOT
I’ve been using this lamp for three months, and when I went for a check-up, my dermatologist actually asked me what I was doing differently because my psoriasis had improved so much! I was proud to say I took matters into my own hands with home therapy.
I travel a lot and love that I can take this with me. My skin stays clear no matter where I go
I bought this to treat my psoriasis on multiple spots, but it’s best for small areas, not large ones. If you need full-body treatment, you might want a bigger panel-style UVB lamp.
Bought this for my 67-year-old mother, and she finds it very easy to use. Her psoriasis has improved a lot after consistent use.
I used to schedule UVB therapy at the clinic, but juggling appointments with work was stressful. This lamp lets me treat my psoriasis at home on my own time. It’s compact, easy to use, and so much more convenient than weekly trips to the doctor.
The first time I used it, I overdid it and my skin got irritated. Once I adjusted my exposure time to the recommended levels, I saw great improvement. Start slow, and don’t rush results!
It’s effective, but you really need to figure out your best exposure time. I started with too much time and got red, irritated skin. Once I lowered my exposure, I started seeing real improvements. Read the instructions carefully!
The lamp is effective for treating small areas like my hands and elbows, but I find it a bit uncomfortable to hold for longer sessions. A more ergonomic grip or a stand would be a great improvement. That said, my psoriasis has improved significantly!
I’ve had psoriasis on my knees for years, and it’s been a constant struggle to find something that actually works. After hearing about UVB light therapy, I decided to try the it. I’ll admit, I was skeptical at first, but after a few weeks of using it, I’m amazed at the results. I have been doing it as customer support advised me and in, maybe, 15-20 sessions I have noticed good results. The redness and flakiness have gone down so much, and my knees don’t feel as itchy or irritated anymore.
My eczema kept me awake every night because I was always scratching. Since using this lamp, my skin feels calmer, and I actually sleep through the night now.
This lamp is a good alternative to going to the dermatologist every week, but you have to be careful with timing your sessions
My eczema used to flare up every few weeks, especially in cold weather. After using this lamp consistently for a few months, my flare-ups have been reduced. I don’t have to apply heavy creams all day anymore, and my skin finally feels normal. If you’re thinking about it, just try it!
I bought this for myself, but my husband started using it too, and it’s helped both of us! His psoriasis on his lower back is almost gone, and my elbows look the best they have in years.
My son has had eczema since he was a baby, and we’ve tried EVERYTHING — moisturizers, allergy tests, diet changes, prescription creams. Nothing worked long-term.
We started using this lamp under the guidance of his pediatric dermatologist, keeping the exposure very short at first (30 seconds per spot). After about four weeks, his skin looked so much better! Less redness, fewer flare-ups, and he’s not constantly scratching
I have psoriasis on my arm where I have tattoos, and I was worried about how this would affect the ink. Thankfully, it hasn’t caused any fading, and the skin underneath is healing beautifully.
The build quality of this lamp is really solid, and it seems like a professional-grade device. My only issue was that the instructions were a little to hard for me.. I had to research how to properly time my sessions. Overall, great device
Before buying this, I asked my dermatologist if it was safe. She said home-use UVB lamps can be just as effective as in-office treatments when used correctly.
I use it three times per week for about 2 minutes per area, and I’ve seen a 40% reduction in my psoriasis patches within two months. The lamp is well-built, easy to hold, and doesn’t get too hot.
I used to wear long sleeves all the time because I hated the red patches on my arms. After using this for a few months, my skin is clear enough that I finally feel comfortable wearing short sleeves again!
I love that this lamp is lightweight and easy to handle
I first bought the corded version of this lamp, the cord length was a bit of short and not really comfy for me as I travel a lot. I had to sit in a specific spot, which wasn’t always convenient. After talking to customer support lady, I decided to switch to the Promax cordless version for more flexibility. The Promax is definitely easier to use since I’m not stuck near a plug. Both are good, but if convenience is your priority, the cordless is worth considering
I have vitiligo on my fingers, and my dermatologist suggested trying UVB. I have just bought it but it looks kinda good, so I will update my review after using a lamp for some time
My journey to get rid of psoriasis was tough. A double lamp for a larger area would be even better. They work the same, just faster with the bigger one
I work with people and I really sweat it about my atopic dermatitis on palms. No attractive rings and bracelets, no nail style will bring your skin a good-looking healthy condition. Having interviewed people, I was prone to anxiety during our talk more than a job candidate. I realized that it is time to change it and put all helpless lotions wall-to-wall standing on my bathroom shelves away. My friend is a derm doctor and she said that phototherapy is one of the most effective ways to treat skin conditions of any degree of complexity. I have decided to order a hand-held UV lamp to heal my palms. It was the best decision in my life. An affordable price and a modern design of my novelty were the only first strengths I found. Right after the first session I understood that there are no discomfort feelings I used to experience when I daubed my hands with lotions. In a week I saw my first results – broken skin around my thumbs became less dry. In a month I realized that atopic dermatitis decided to leave my body! I took a photo at the beginning of the phototherapy and the passing result for now. My treatment goes on for about 3,5 months. I recommend people with eczema and dermatitis to try this UV lamp. Do not be afraid of side effects – as for me, I have none of them. Now I visit a nail master once a week and gesticulate away actively. I am proud of my beautiful hands and the same I wish to you – love your body!
AAA+
The analyzer did comply with what was expected at selection for purchase.
I have a bad sight so the screen feels too small for me. Overall, I’m happy with the lamp and the results from my home phototherapy. Quick 2-minute sessions in the evening are much more convenient than daily trips to the dermatologist.
I bought the lamp online, got it in 2 days, and kicked off my home treatment. The instructions are detailed. I used the built-in timer once, now just turn the lamp on and off. Eczema spots on my palms are shrinking, but I’m hoping for quicker results.
I love the wand design, and the special comb is perfect for treating my scalp psoriasis. The phototherapy gave me results I never imagined with pills. Ordered the KN-4003BL online at a great price.
I saw some crusting on my baby’s scalp. My decision was to visit the dermatologist’s cabinet as soon as possible. This pretty woman suggested some special shampoo for me to buy. She said that nothing serious, just some kind of infantile sensation. However, after a month of treatment I did not notice any positive effect. I was disappointed because my son started to scratch his scalp and sleep badly. I understood that the diagnosis was made wrong. Another derm doctor was more experienced and saw the scalp seborrheic dermatitis from the very beginning. I was afraid of the progress of the skin condition and was ready for any needful measures. But I was surprised when phototherapy was recommended to us. I could not imagine how a small kid would pass sessions under a UVB lamp but, of course, I bought this device. The result was astonishing. I just explained to my baby that it is a special comb that will shine bright when your favourite song will be played. Right after the first session it became our favorite everyday activity. Just look at our BEFORE-AFTER photos. Now, after several months of phototherapy skin is almost healthy. My son is not afraid to comb hair because this procedure is painless for him. He sleeps sweetly and smiles more often! My 4 stars are because of a previous awful experience I had. At the same time I have no complaints but many thanks to manufacturers of UVB lamps. You are my saviours!
Great product!
After my dermatologist recommended a 4-month phototherapy, I reached out to an online shop specializing in UVB lamps, seeking a model for my allergic eczema. Unfortunately, I mistakenly ordered the KN-4003AL/BL for Saint John, where I used to live. The delivery took longer than expected in my current location in Morton. 🙁
My husband and I use the UV lamp KN-4003BL together – I’m treating my segmental face vitiligo, and he’s trying to alleviate his chronic atopic dermatitis. We’re genuinely pleased with the results we’re seeing. The lamp cost us about $300, which is only a third of what we used to spend on our monthly clinic treatments! It’s been a game-changer for us!
I used to hate my body and dream of healthy skin my whole life. Plaque psoriasis shattered my confidence, causing pain and discomfort day and night. After trying various lotions recommended by three dermatologists, spending a fortune on treatments, and feeling exhausted, I found this lamp online four months ago. Its home-based usage suits me as a busy housewife with two small kids. The device is convenient, fits in my small bag, and the built-in timer makes sessions hassle-free. Just a single purchase brought me immense happiness! Check out the photos of my arms before and now – the difference is incredible! Thanks to this lamp, I forgot what it’s like to constantly scratch myself. I’m now buying new tops and sleeveless dresses, living a dream that came true! I hope for remission and truly healthy skin soon. With my reliable assistant – my UV lamp – I’m giving it 5 stars, without a
doubt!
worked perfectly
Very easy to operate and lightweight. It was my last attempt to overcome my psoriasis, and I seized this opportunity. I couldn’t find a better option, even at a higher price.
Excellent device for treating scalp psoriasis – I discovered firsthand. I believe that modern healthcare consumers deserve such convenient home-based units for managing skin conditions. I’ve been using it at home for five months. When the scalp comb broke down during the warranty period, I received a new lamp with a full package – truly awesome service!
