Not only is there no problem having Botox (or another neuromodulator) after Vivace but it's actually a good idea. We encourage Botox within close proximity to treatment to prevent lines and wrinkles from recurring as quickly as they otherwise may with repeated, habitual muscle contractions and expression. Treating the lines is better and more effective if we treat the underlying muscles in conjunction. So, not only are you continuing to improve your appearance with both but helping to maintain your results.
Vivace treatments and Botox treatments provide an excellent compliment to each other and the RF will not effect the toxin. I would suggest waiting 24 hours between each treatment. Botox will help the dynamic wrinkles on your face, while the Vivace will improve skin texture and fine wrinkling.
