Plagued by dry, cracked feet? A pedicure may be the first thing you think of but all you really need is a jar of petroleum jelly, a pair of socks and a good night's sleep. Smooth a thin layer of ointment on the top and bottom of each foot before going to bed (the socks help keep the jelly on your feet, not your sheets) and wake up in the morning to find hard skin has been softened and cracks gone. By healing dry, cracked and calloused skin, feet become more resistant to blistering and hot spots.
Similarly petroleum jelly can help your hands, next.
