Age Limit for Sculptra?

Yes, Sculptra can still be used.  I would encourage you to see a board certified plastic surgeon for an evaluation to see how much Sculptra would be needed. 

You will never be too old to look younger and what a good opportunity to replace lost volume with sculptra. I would not hesitate to use this and have used in many seniors. 

While there is no true age limits for Sculptra, from my professional experience, I have found that younger the patient going through Sculptra injection, less vials, and less treatment injections may be needed vs. someone who is much more mature with more significantly deflated complexion where much greater volume replenishment and additional injection treatment sessions may be required. This has to do with the fact that there has to be a relatively healthy mechanism of collagen production for Sculptra PLLA to work effectively. I have found for patients in their 70's and older, Radiesse may be more appropriate and gratifying for cheek augmentation and volume replenishment as there will be less dependence of the innate collagen production capacity.
