Shootingstar,
Not sure if we have the same problems or not... but here goes. I have chronically dry skin, which I thought would improve when I moved to the deep south, but it didn't.

Check that the lotion you use has lanolin as one of the prime ingredients. Lubraderm comes to mind. Or see if you can you can find lotion with vitamins A, D, and E, then add some lavender oil and rosemary oil - smells good, and the essential oils will improve circulation and help healing, as will the vitamins. Unfortunately where I was buying my lotion that really helped my legs was shut down by the IRS, some little detail about non payment of taxes. Bah Humbug! They had lotion that worked! Pooh.

Of coures, making sure you're drinking enough water is also important.

Genetics doesn't help (part of my problem).

Unfortunately the humidity in the air doesn't necessarily translate to happy skin.
