I had this problem not that long ago. What I did was after I took a shower I'd rub the area of my nose with my towel so it would get the dry skin off and then I'd use Jergens Ultra Healing lotion. It works pretty well.. After about a week or so of doing this the dry patches were gone.
When i get dry patches, i put vaseline on overnight. and wash your face in the morning. it seems to work.
I use a dab of carmex. Also goldbond lotion is good for dry itchy skin.
Moursturize!!!!!!! Thats not how you spell it but oh well!
You can find some special cream at store
