It sounds like she might be allergic to one of the products she uses. Has she tried using one of your after shave lotions that you use on your face? Right now I am using the Avalon Organics Lavender Daily Moisturizing cream. A little bit goes a long way and it works wonders.
Nivea for Men sensitive ASB works for me, Aveeno makes good lotion, and L'Occitane Shea Butter Hand Cream is amazing stuff. They may have just discontinued it, though, so you would have to check a local store. It's expensive, but it's the business.
