Red Skin On The Side of My Face

About a year ago, all of a sudden I noticed like red on the side of my face. Its like on the cheeks. In the middle of it there is a circle (not a perfect circle) but the color is white (but more like my skin color). This is only on the one side of my face. The other side of my face is just a little red, the side I referring to is darker red. It runs up past my side burns and under my eyes. Honestly it basically looks like sunburn with a white circle. I took a picture and circled because its kind of hard to tell in the photo. I also circled the white circle. I went to the doctor and he just said its probably just dry skin use lotions... I tried and no luck to get rid of this. Please give me some advice. Heres the picture so you can see for yourself (the redness is still kind of hard to see because of the lighting in the photo).
