Melaleuca RENEW intensive skin therapy is the only thing that will keep my hands smooth. I've been using it for more than 10 years, and don't need anything else. I use it on my face also. No cracks or dry spots.
And don't forget about Aloe Vera. From the plant, not from the store. The processed stuff just does not do it. That is the best healer if you get a scratch or cut from anything.
I cut off a piece of leaf, cut it in half to expose the gel and use a piece of tape to hold it on the cut. Leave it there for a day or two, and the cut is GONE. I have dozens of little plants right now. They propagate easily and are very easy to grow. Just don't water too much.
