What treatment would you recommend for my hollow temples? (photos)

1 treatment of sculptra will not help your temples, you need a series of vials to get a final result.  I would keep to your course and if you are with a well trained sculptra expert, you will see improvement.  If you will not continue, then Radiesse in my opinion is the second best when it is put deep onto the bone and then perlane or voluma superficially.  Find someone who specializes in this.  Best, Dr. Emer.

We achieve our very best results not with Sculptra, which is effective but temporary, but with autologous fat fascial grafts.  In the majority of patients, these grafts are permanent.  They come from the patient's own tissues and are fully viable when they are placed.Many doctors achieve very nice results with fat injection as well.Because the area is hollowness is deceptively large, considerable amounts of Sculptra are often required for an adequate result.

It is very common for sculptra to require 2-3 sessions fill the temporal hollows.  It would be unusual to get it perfect after the initial injection (unlike other fillers).  Usually, these injections are done at 1 month intervals.  I think its fine for you to have another filler injected at this point if you would like further filling.  Some of the better options include Radiesse, Voluma (1-2 years) and bone filler (permanent).  All the best!
