Magic
I've developed eczema on my hands over the last few years, and my fingers get terribly, painfully cracked all year long, and especially in the colder months. My fingers and knuckles will be covered in cracks. This is THE only thing that gives me any relief. It stings a good bit when you put it over open sores (which if you're like me is inevitable), and feels a little weird, but the result is worth the pain. You'll notice a difference after just a couple of uses. Promise. It helps cracked heels, too.

Just works!
Only thing that works for dry cracking hands! Better than most more expensive brands such as Neutrogena and L'OCCITANE. See my before and after pic.
