Hrm... try the beauty section of your local grocery store for the gloves- that or the makeup counters at a department store. And yeah, urea. It's not actually urine (which has a bunch of other stuff in it) but it's a component of urine.
From Wikipedia: "Urea is used in topical dermatological products to promote rehydration of the skin."
