Ms. Grace, I too have very dry and cracked thumb and finger tips, Eucerin is good. I use Burt's Bees Almond Milk Beeswax Hand Creme. I know that for me, it heals my fingertips and thumbs practically overnight. One caution, it is oily, so you don't want to use it and then go to work on a quilt. I've also used Gold Bond Healing (in tube) and it works well, too. I like the Burt's Bees Almond Milk Beeswax Hand Creme because it works best. It's a little more expensive than Gold Bond but it goes a long way. I feel for you, because I know what it feels like. Hope your hands heal quickly!
