Is it advisable to use Sculptra to volumize midface where dermal filler was used?

I'm thinking of layering Sculptra with dermal filler to volumise my midface, but I'm not sure if it's wise to use Sculptra where dermal filler was previously used considering the risks of nodule formation. How long do I have to wait between Sculptra and dermal filler injections in order to reduce chances of complications? As I haven't found a medical practitioner that has experience with using Sculptra in my area, I'm doing dermal fillers first.
