I'm no doctor, but I think you may be describing subhorretic dermatitis (spelling?). I used to get dry, reddish skin patches under my eyebrows near my nose and around my nostrils. Try a zinc-based soap (there's something called ZNP bar that I use) and use for a few days. If that's what it is it will go away immediately, otherwise it could be something else. That's what I have experience with.... good luck.
