When I have those nasty tender cracks on my fingers tips I use Super Glue to basically glue the edges together..I usually trim the hard edges off and wash well and dry then apply the glue..takes the extreme pain out overnight and fasiliates (sp, to lazy to use spell check) healing.
For a really great hand cream I use Aveeno Daily Moisturizing Lotion. You can buy the fragrance free. It's great and is not greasy. It's the best I've ever used. I buy it at Walmart but you can find anywhere.
