Product Reviews

Wish we had found it earlier!
The itchiness on shoulders and neck are completely gone! I bought this for my mom as a Christmas gift, and she’s been using itf ever since. She struggled with stubborn patches that creams couldn’t fix, but this lamp works! It’s a bit pricey, but absolutely worth it.
-
Delivered on the 5th day
I need a stronger lamp for my legs. I’ve used this type of lamp before at my doctor’s office, so I have a good idea of how it works. Having my own at home would be much more convenient.
-
Worth it
My doctor recommended home light therapy for my Vitiligo, so I researched multiple devices before choosing this one for its stronger light output. I’ve seen clear improvements. My skin has cleared up, and pigmentation has reduced.
-
Reliable
I was searching a UVB lamp for the larger patch on my chest and came cross this machine. I've noticed really good results after the first few weeks of use. The itching has reduced. It is worth considering for those who are looking for a uvb lamp.
