Can you do Morpheus8/radiofrequency after Radiesse and Novathreads?

Yes, you can have Morpheus8 treatments after fillers and threads. If the fillers were placed in the deep, periosteal plane wait until the area heals (1-3 weeks). If the fillers were placed superficially you should either avoid those areas during treatment or wait until the filler product has been dissipated (up to 6 months) just to be safe. Furthermore, after Botox treatment patients only need to wait 1 week before undergoing Morpheus8 treatment.

Thank you for your question!  I would talk to your doctor about it as he might be able to avoid the threads.  In our practice, we perform a non-surgical face lift / skin resurfacing treatment using Renuvion Helium Plasma Radiofrequency. To get the most improvement with skin tightening, we combine Renuvion (formerly J-Plasma) with lasers (Fraxel, Clear + Brilliant, CO2), microneedling/PRP, Ultherapy and InMode FaceTite. I suggest getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

Hello, anikaxo!
Initially, InMode did not recommend ever getting Morpheus after fillers or botox.  Now we know that Morpheus is safe 10 days after Botox injections and 10 to 14 days after getting deep filler implants. 
Its best to wait the recommended 2 weeks before getting Moprheus8 after any time of filler. 
As far as the Nova Threads, I would wait atleast 2-4 weeks before getting anything done to let things settle. 
Best of Luck!
