In reply to The Potato:
lots of suggestions here, thanks for taking the time to reply everyone, not sure if any of it is going to be useful, as said ive tried moisturisers of various kinds. Forgot that Id also tried climb on which is good for well climbing on, wax type hand rub.
I use alcohol hand gels at work but they dont seem to help either, i agree with the sentiment of washing hands less but in a healthcare setting Ive no choice.
I will look in to the urea/urine option as well as just rubbing my hands in rough stuff more often, oh look its nearly spring, gardening awaits.
Anyway Ive always been a very practical hands on person, on the farm in the garden etc but always had similar problems.
