At almost 60 years old I got cracked fingers for the first time ever- first one thumb, and about four weeks later the other. I tried everything I could think of- triple antibiotic ointment, tea tree oil, tamanu oil, jojoba oil. Nothing worked. While browsing Amazon one day I ran across this Hand Repair Set from Burt's Bees. From the very first night I'd applied it my thumbs felt better. Within a couple days the pain was gone, and within a week they were healed completely. I don't know what's in this stuff, but I'm a believer: for cracked fingers it's GREAT!
