What is the Best Treatment for Fat Loss in the Face? (photo)

As others have mentioned, the amount of Sculptra and the # of treatments may have been sub-therapeutic, thus explaining your lack of noticeable improvement.  When adequately treated, it does provide subtle but significant, and long-lasting volume correction.

Fat grafting is also a great long-term option, although it is "surgical" because fat must be harvested from your body (liposuction).  Fat grafting does tend to leave you more bruised and swollen, and for a longer time, than any of the dermal fillers.

All of the treatments you mentioned (Sculptra, Radiesse, fat transfer) would be options to replace volume in your face.  Normally, the main reason you would not achieve improvement with Sculptra would be that not enough product was used or that you did not have enough treatments.  The result with Sculptra should last two to four years, while the result with Radiesse would normally be gone by a year.  Fat transfer results can vary and because it is more of a surgical procedure, I would say there definitely is more swelling and bruising than you would see with either Radiesse or Sculptra treatments.
