rash on chest and face

I have had a rash for several years on my face (across nose and cheeks) as well as on my chest (neckline).  A doctor told me that it was tinea versicolor.  In looking at the images on the net of tinea, I do have spots of it but it is not what the rash on my chest and face is.  The rest of the rash is not circular and does not respond to any of the creams or medications given to me. This rash is just a general redness.  It does not occur anywhere except the area of my chest that is normally seen through a neckline opening and across my nose and a little bit of my cheeks.   I am 50 years old.  Any suggestions?
