SeptemberMom,
The only thing I haven't seen mentioned here for dry skin is good old Vaseline. The soles of my feet were badly cracked and dry for years. I tried every foot moisturizer on the market and none worked. Then a manicurist told me to try using Vaseline every night--slather it on when you go to bed. It's done wonders! I have also used it as an all over body moisturizer. I apply it all over at bedtime or anytime I'll just be hanging around the house, doing assignments, etc. It works great for me. And cheap!
