Filler after dent on forehead caused by Cortisone Injection?

Depending on the degree of the depression you could utilize a synthetic filler if small or can undergo fat transfer if slightly bigger.  In my experience fat transfer not only correct the contour to forward it but helps regenerate the thin skin from the steroid injection.  In my experience in treating this same problem, fat transfer not only corrects the contour deformity but helps regenerate the thin skin caused from the steroid injection. This comes from the power of the stem cells that are transferred with the fat.  Typically a fat transfer procedure can be done in the office under local anesthesia or oral sedation and the results should be permenant.

You absolutely can get Restylane injected into the indentation.  It is temporary and should fill it completely and have a good result.  Best, Dr. Green
