Strange texture on butterfly area of face.

Hi, I have this strange texture on my face in the butterfly area but not on nose. No doctor or dermatologist so far has identified what it is. I have rosacea but not overly red. I Did a blood test for lupas was negative. Hard to take a photo but the skin is thickened and looks like a burn scar. I have had laser before all over my face and the butterfly area is only affected? I'm sure it's a type of immune disease or disorder. The areas are slightly red and thick skin, no pores. Please help!
