Just get a good thick cream moisturizer that you like for her and add glycerin to it (maybe about 1/3 to half the amount of glycerin like a 12 oz cream with 4 to 6 oz glycerin) and moisturize. When going outside into the cold use petroleum jelly lightly on her face and even her whole body. From personal experience, if I put petroleum jelly on too thick it makes my face itch. Try to avoid taking her out into the cold within under two hours of a bath or shower. Going out in the cold shortly after a shower dries me out really quick.
