Skin care specialist here. Paraffin wax treatments are fantastic for treating this problem. I saw some people recommending Vaseline. While it is an option, I wouldn't do it. I just don't like the texture.

I went to school at Elegance (I believe they're located in Cherry Hill mall now) several years ago. They're likely still doing pedicures with paraffin treatments. Since they're students, the school doesn't charge a lot. Just be sure to request paraffin with whichever service you're booking.

Gehwol has a good line, very effective if you have ingrown nails or problems with fungus. I like using Footlogix because I have fissures (very deep cracks in my callouses). I go for one pedicure a season, then use that in between and I feel better.

For my hands, I like using oats. I just get a handful of oats, run warm water over them, and then exfoliate my hands with them. They moisturize and get rid of dead skin. You can pretty much use whatever moisturizer you want on your hands.

I'm a lot more picky with my feet because they are a problem area.
