Lotions and oils are good, but they are really just temporary fixes. They don't stop what's causing the dry skin, they just help the skin not be dry.
Carbs are not evil, though I don't know of them having an effect on skin. I would try more fats and oils; I know people who have had success with fish oil tablets, as well. Really, you gotta fix it from within, too, not just cover it up with lotions and oil. Try the fats/oils in your diet, and if that doesn't work I would maybe see someone about it. I also knew a person who had an issue where skin grew too fast, and thus had peely feet/hands.
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
