Thank you for your question. Kybella is a permanent treatment for eliminating fat under the chin. The time between treatments will not hurt the results however you will not see your final results (meaning after all the treatments needed) for some time if you wait between treatments for a period...
Thank you for your question! Kybella acts locally and it should not interfere with IVF. Share your concerns with your physician so s/he can address your concerns. Good luck!
I recommend that my patients take it easy for 24 hours after their Kybella injections. Going to the sauna a few days after your injection won't have any effects on your results.
