How soon do I have to wait to get J Plasma after Morpheus8?

We use bodytite after Morpheus (no waiting time required) and this gets a very good result for tightening of upper arm skin. It's an office procedure too, so come and go!

Although they can be done together. I would suggest waiting up to 3 months and then have the Renuvion. I am not a fan of PDO threads.

I am sorry that you have not seen the results you want thus far, but single treatments of non-invasive therapies like Morpheus and threads are unlikely to show much difference. This is why the price ads up and I support your decision to move forward with J Plasma. J Plasma is the most effective non-surgical skin therapy.
Morpheus and J Plasma can be performed at the same time. They address different aspects. Morpheus addresses the dermis by creating inflammation in that layer. J Plasma primarily affects the fibroseptal network but also the underside of the dermis. Therefore, there is no waiting period needed between these two therapies.
The heat from J-Plasma will cause the PDO threads to prematurely dissolve, but there again is also no time specifically needed between the procedures.
We perform the J-plasma for arms "awake" and in the office. Let us know if you would like to make a visit to Tampa !
