this may be old news dont know spoke to my derm today & she told me this.
if your lucky to be in Wales - Cardiff then your more than likely administering your uvb at home - just like the Americans - from what i could gather the welsh derms are very happy with the results and my derm did say this could well be rolled out across the UK...
would like to hear if we have anyone from cardiff - either taking this treatment at home or are you under the Cardiff hospitals??? maybe find out more for us..
