I used to suffer terribly with chapped hands especially in the cold weather & the skin on my fingers would crack & bleed so I sympathise with your OH. Someone told me about this site

The product, Gloves in a Bottle has made a dramatic improvement for me. I actually buy mine from a local garden centre stand & although its certainly not cheap, it lasts for months & months. The bottle I bought in May 2009 has just finished so it works out very economical. Shame we can't send each other a private message like other sites as I have a sample packet I could have posted to you. Do hope this info helps
