My first experience of NBUVB in 2008 kept me pretty clear for about nine months.
My second experience of NBUVB in 2010 was nothing short of a disaster. I had a massive flare-up half way through the treatment, which resulted in me getting burnt. And I finished the treatment, more or less, back at where I started.
I don't feel that I am being very helpful, but that is what happened.
I probably should add that I spent many years working in some very hot countries and while, at the time, I used to tan very easily it has taken a toll on my skin. My Derm describes it as being like "tissue paper". Although the steroid creams may also have done damage in this area.
