My hands get so dry during the winter, with all the washing dishes in hot water, laundry, and bathing the younger kids. I use lotion after I dry my hands, but sometimes my skin needs a little boost.
About once a week, I make my own exfoliant using simply a teaspoon of salt and about a teaspoon of olive oil. I pour them into the palm of my hand, and rub my hands, paying special attention to the driest parts, for about a minute. Rinse the mixture off with warm water and a bit of soap, and your hands feel like they've been to the spa!
