Thomas July 12, 2026 psoriasis

Finally stopped scratching at night
My psoriasis was not extremely visible, but the itching was driving me crazy, especially at night. After several weeks of UVB treatment, I realized I was sleeping without waking up to scratch.
Stephanie Ward May 28, 2026

Much easier than driving to a clinic
Much easier than driving to a clinic
The nearest phototherapy center is almost an hour away. Home treatment saves me several hours every week and makes it possible to stay consistent.
Nicole April 12, 2026

I expected faster results
For the first month, I honestly thought it was doing nothing. The changes became more noticeable later, so this treatment definitely requires patience.
Andrew Parker March 29, 2026

I had two thick psoriasis plaques on my elbows for years. They are now much thinner, lighter, and no longer constantly shedding flakes onto my clothes.

Works well, but treating my back is difficult
The lamp is easy to use on my arms, stomach, and legs. Reaching the middle of my back alone is another story, so I usually need someone to help me.
