I've found 2 good hand lotions that work great for keeping my hands and skin moist and prevents my hands from drying out.
Those 2 good hand lotions are the Neutrogena Norwegian Formula Concentrated Hand Cream and the Burt's Bees Shea Butter hand Repair Cream.
You can also use some Vaseline to rub onto your hands to help seal in moisture and prevent dry skin on your hands.
You can also buy a Vaseline hand lotion which is called Vaseline Intensive Care Advanced Repair and it works great as well.
