The best thing to use is 100% Shea butter. You can go online and find small companies selling it. Actually, most of those companies are black women owned, they import the shea nut, it's a HUGE, bigger than a basketball, nut from Africa and then they divide it into small containers and sell it that way. You can get either refined or not, refined will just be a little whiter. It's what my girlfriends and I use for our heels, it does an amazing job. My sister is a nurse and her hands were cracked really bad from all the washing, I sent her this, found someone selling it at a craft show, she has spent big bucks on other creams and this cured her, now she's a convert for life. It must be 100% though.
