Should I still use creams?
Roche recommends that you use a cream or lotion on the affected areas during the day and an ointment at night. Their lotion list includes Aveeno and Lubriderm. At bedtime you put on a really thick ointment like Vaseline or Aquaphor or Bag Balm or Eucerin's heavy duty cream, and then you put socks on for the night.
Some people feel that this works. For me, it helps my skin to be in good shape, which has got to be a good thing. I've done it for years during the winter in cold climates and in the summer in hot climates.
