I have tried just about everything. My fingers get cracks around the nails. They hurt sooooo darn bad.
I have to put a thick lotion on my feet before going to bed or they wake me up at nite cracking. I have been getting regular pedicures which has helped some.
I put on a heavy cream everytime I put socks on.
For my hands, like Micki I like Gold Bond Ultimate. Also Nexcare Advanced Skin Cream and Vaseline Petroleum Jelly cream with Cocoa Butter works good. They are both kind of heavy so I use them at nite. Regular Petroleum Jelly works very good too.
I bought a huge bottle of Suave dry skin lotion with Oatmeal for work and it feels so good just to put on after washing my hands!
I also bought a humidifier for my bedroom to run to help with the dryness, b/c one day last week I woke up with a nosebleed.
