Properly performed facial fat grafting will eliminate your forehead issue. Your forehead contour is due to a loss of facial fat pads; often times the temple and lateral cheek(hollow or flat when you smile) can also be involved.
By saying "properly" I am referring to the fact that some fat grafting techniques are done in the operating room(once) and others require multiple treatments in the office. Fat grating success is highly technique dependent from harvesting the fat to be grafted from the donor site---leaving an aesthetic donor site behind--- to processing and refining the fat grafts, and finally injecting fat optimizing successful transplantation as well as smooth aesthetic contour. Our fat cells are our body's most potent stem cells so they can increase blood supply slowing or halting the progression of your issue with age.
Hope this helps

Those are classic forehead horns which can be removed by a bone burring reduction technique. They are raised areas of bone that occur from the original embryologic development of the forehead.
