If you struggle with psoriasis you may qualify for a non-cost clinical study
I'm interested
Operating the device is easy. Deciding the correct exposure is not something I would guess, so I’ve followed the treatment plan carefully.
I only have a localized psoriasis spot on my knee. A full-size panel would be unnecessary, so a handheld device makes much more sense for me
I found that it is almost the same machine my doctor use so I bought it right away. Great finding
