4 Vials of Radiesse Only Lasted 6 Months?

Radiesse is a thick product compared to other fillers. It's very rare to not see any result from your treatment. Fat Grafting may be your best option to promote a lasting result, this procedure consists of removing your own fat to re-implant it where it's needed. Without a photo provided you would need a full examination, I suggest seeking an evaluation by a reputable board certified physician who can achieve the result you desire.

Radiesse is a great product that typically lasts longer than 6 months, especially when such a large volume is used.  Some people do seem to go through fillers faster then others, but its difficult to say what the reason is. If you really liked the look of your fillers, it is worth considering a more permanent option such as autologous fat transfer (grafting).  This procedure requires harvesting your own fat from your abdomen or thigh area and injecting it into your face.  This procedure is more cost effective when you want to fill large volume areas such as the cheeks, since most people have a good supply of donor fat.  I personally prefer fat transfer over sculptra, but you should discuss this with an experienced facial plastic or plastic surgeon in your area.  

I agree that it is costly and Radiesse product is costly. We charge 750 for 2 vials and 3 vials probably cost you 1200 - 1500 dollars, depending on where you live and who injected the Radiesse. Radiess is a good product and typically lasts 12-14 monts but can last as litlle as 6 months. I also sugges autologous fat transfer which should cost you about 2,000 and should last longer than 14 months.
