Hi J.,
First, I would try Body Balance. It's a liquid nutritional supplement made from aloe juice and sea veggies.... it's extremely hydrating (due to the aloe content) and many people have had great results w/ skin issues such as yours. You can find it here: http://www.LifeForceSucces.com.
As far as a dermatologist, I recommend Sheila Boyle. She's in Westminster and here's her address:
9101 Harlan St Unit 155
Boyle Family Dermatology
Westminster, CO 80031
I don't have her # handy, but you can find it on Google.
Hope this helps and good luck!
