Fat Transfer for Temporal Hollowing
Hollowing in the temple area is rather common with aging. Fat injections to this area works quite well. It does not require shaving of any hair. It is done through small injection sites that typically leave not residual scars. The fat transfer is quite technique dependent, search out a surgeon with lots of experience with the latest techniques.
