I don't have info for you on creams available in the UK. There are some folks in the UK with Ichthyosis that do post on these boards once in a while.
I found this web site a while ago. It's a UK ichthyosis support group: http://www.ichthyosis.org.uk
I don't know how active these folks are, but they, in addition to the folks at FIRST www.scalyskin.org
might be able to help you find local resources.
In the meantime, welcome, continue to ask questions, and I bet as it draws closer to the weekend, folks will respond a bit more with suggestions. Sometimes it takes a few days as folks may not log on and read the boards until later in the week.
