Hi R.---I have dry skin that doesn't look like it. But when this weather changes and the furnace starts to come on, I need to use lots of moisturizer. I also suggest giving her ground flax seeds whenever possible, as it contains omega 3 fatty acids. Walnuts and pumpkins seeds are another good source. I know that eating more foods rich in omega 3's can help skin conditions.
Be sure she is eating as many fresh fruits and veggies and drinking as much water as possible. This will also help her body to do what is necessary to keep her skin adequately hydrated and possibly not feeling dry and itchy. Good luck, be well...D.
