Can Rhinoplasty discolor your skin months after surgery? (photos)

I had rhinoplasty almost a year ago. About 8 months after the surgery the skin on my nose has changed to a brown color. It seems to be concentrated in exact area as where the surgery had been performed. If so then is there away to change the color back to a normal looking color? I sent some pictures for you to view. I appreciate any help I can get. I went from having a complex for a large nose to now having another complex to the same area Looking forward to your response Thank you Lisa Balint
