Eczema?? Very dry skin problem on hands..HELP!

[unknown]

Help...if you can please.... A female friend of mine started having...
what the doctors believe to be eczema. Her hands..the underside 
mainly...get VERY dry and crackly. For some reason, tanning helps
some. 
The doctors have done some allergy testing but could find nothing. It 
started about 2 years ago when she started a job as an administrative 
assistant. Currently she is dealing with it like many people...but if 
anyone has ANY ideas or places to look/things to try?? Please email 
me with any with info.....thanks.....jake_tx at hotmail.com
