Vasoline on your hands and feet before bed and put two pair of cotton socks over your feet and cotton gloves over your hands, when you wake up your hands and feet will feel wonderful! I'm sure you could do it with your whole body but you would want to put cotton pjs on that you don't care about because the greesyness wouldn't be good for them and cotton allows your skin to breathe so that it can get softer!!! Good luck!
its going to be really hard unless you use brands. you cant get certain lotions and body washes to repair dry skin and moisturize it. my fae is the dryest part of my skin so i got this special cream for it and it works pretty good. you can browse around and find some really good home remedies if you look hard enough. wikihow is a good search engine for stuff like that. if your skin is so dry that that stuff doesnt work very well then try seeing a demetologist. (spelling?) :)
