I like Lush's massage bars... But they not all I use, either.
I second the vegetal oil vs mineral - most cheap moisturizing products are fulla mineral oild which won't do you any good in the circumstance. Also, don't forget that hydrating is done from within, too: up your liquid intake, drink more water/herbal teas and juice (remember that tea and coffee don't really count as liquid intake because of the diuretic effect)...
