PDO Thread Lift after cheek filler?

There is no minimum length of time to wait before adding threads to facial fillers. In fact, we often insert PDO threads for a lift through the same cannula insertion site that we use for injection of fillers at the same treatment session. We have been seeing excellent results with combination treatment. Hope that this information helps and good luck! 

No actual guide lines, personally I would wait 3 months. Why? I would like to see the eventual effects (if any) in the jowl area, this way you may require less filler. Additionally the placement is more natural as collagen has matured from the PDO lift. If you are having fillers away from the cosmetically treated area e.g. upper face, whilst PDO for lower face, yes, certainly safe at the same time. All the best, Dr Davin Lim. Brisbane. Australia.
