Megan, for hands and feet a fantastic over night treatment is to wet them and then apply a nice rather thick coat of Vaseline and cover feet with white cotton socks and hands with white cotton gloves.
I have also found that--- Udder Cream works great but it has lanolin in it many people are allergic to lanolin.
AND if you just want a good hand lotion for daytime use - HEMP hand lotion is great. Yeah, I know, hemp - believe it or not it has many good uses that doesn't require smoke!
