Wide, white scar and lumpiness 7 months after lateral brow lift and fat transfer - advice?

I went to a very reputable surgeon seven months ago and had a lateral brow lift and facial fat transfer. I had an enormous amount of swelling in the months after. In the past couple months, I’ve developed wide, white scars and weird lumpiness near one temple. My surgeon had assured me that my scarring would be minimal (I had hairline lowering 8 years ago that left a tiny scar at my hairline), but this is obvious and unsightly. Is this normal and can it be improved?
