    The lamp is bigger than I thought, but it would be great to treat my legs and feet.

    Would recommend

    Posted by Matthew on March 27, 2025

    I have vitiligo on my cheeks, jawlines, shoulders, and back, so the double-bulb lamp is exactly what I'm looking for to treat these larger areas.

    Posted by Cyn on March 24, 2025

    I used this device for the first three months to treat psoriasis on my torso and arms, and I’ve seen great results. The raised red patches have become much smoother, and the flare-ups and itching have calmed down significantly. I only wish I had found it sooner! The attachment helps maintain a safe distance from my skin, and the larger treatment area lets me cover more skin at once, making the whole process much faster.

    It works!

    Posted by K Maffeo on March 21, 2025

    I am very pleased with the results. I purchased the device in December and have been using it for three months. The pigmentation on my hands and arms affected by vitiligo has recovered by about 80%. The treatment requires patience and consistency, and you really have to make it a part of your routine, but the results are absolutely worth it.

    Great Machine

    Posted by Anonymous User on March 17, 2025

    The lamp is about the size of a Stanley cup. I was initially intimidated by its size, but surprisingly, it's lightweight. While the user manual is a bit confusing, the machine itself is easy to operate. Since I have large psoriasis areas on my back and legs, a lamp of this size is incredibly useful

    Psoriasis on the lower back and abdomen

    Posted by Thato on February 21, 2025

    I chose the KN4006B because I have a larger patch on my back and abdomen. After using it since November, I’ve noticed obvious improvements—less red and shrinking patch sizes. I’d definitely recommend it to others dealing with similar skin.

    Stationary Design is so helpful

    Posted by Juan on February 17, 2025

    If you have psoriasis on the back of your hand and wrist, the 4006B is likely a better choice than the 4003BL2D because you can let the lamp stand on its station.

    Works great

    Posted by Goten on February 13, 2025

    It works great for home use! It took me about five weeks to see improvements in my skin, and the pigmentation on my fingers and palm are shrinking.

    It works

    Posted by Kim D. on February 13, 2025

    I was initially worried that the lamp might be too heavy, but that’s not the case at all. It’s lightweight yet well-built and compact. The lamp size is perfect for treating the psoriasis on my legs. I plan to use it three times a day and see how my skin responds. Excited to track the progress.
