Can both Restylane Defyne and Sculptra be injected at same time/in same place? Specifically lower face chin/jaw. (photos)

I often use combination fillers to get immediate results from some of the hyaluronic acid fillers and the more long term collagen stimulation from fillers like Sculptra.  By injecting the Sculptra deep to the hyaluronic acid fillers you can create a scaffold with the additive results from two different types of fillers.  Sculptra will take several sessions to reach its full potential, and typically these are spaced 6-8 weeks apart.

Yes, all the mentioned fillers, Refyne, Defyne, and Sculptra can be injection simultaneously in the lower face. Refyne would be most superficial. As stated in your other question, injection of the Refyne and Defyne in the dermis has give quite long term results which I attribute to collagen stimulation. Adding Sculptra will provide longer results as well by further collagen formation.
