I did Kybella 2 weeks ago and I want to combine it with another treatment right away. Do I have to wait?

Ideally you should wait 6 weeks post procedure for full effects from the Kybella treatment and for any swelling to subside.  Kybella can provide fat reduction along with some skin tightening. After that you will have your true baseline and additional treatments such as Thermage or other radio frequency treatments for skin tightening or laser lipo for fat reduction can be used. If you're on a timeline to get things done more quickly it can be done two weeks post Kybella, but would be ideal to wait the full 6 weeks post treatment. 

Usually KyBella injections has a few weeks of swelling i the injected areas. After the swelling subsides by about 2 to 3 weeks other interventions, like lipo can be offered or preformed. But best to be examined in detail prior to proceeding with any additional therapies in the injected areas.
