Sit around all day with your hands stuck in a bowl of hand cream
Seriously, who ever had hands as soft as their face? The nature of the skin on each organ is different, one usually has a layer of fat under it, the other doesn't, at least, not on the palm of the hand.
I have very dry skin so usually wear marigolds for any household task involving liquids and have done since I started my first flat share, and when I wash my hands i put handcream on. The main purpose of that is simply to avoid the very unpleasant feel of dry hands, rather than achieve some ignorant male copywriters idea of what women want.
