Does it matter how long you wait for a second Kybella procedure? Is it still as effective, if I wait 2 months?

Six to eight weeks is usually recommended in order to give the treatment area time to heal before the next procedure. Two months should be a good time between treatments and should not negatively impact the results in any way. Make sure the doctor you work with is board certified and has extensive experience administering Kybella to ensure you achieve the best possible results from your treatment sessions. 

I see my Kybella patients back 6 weeks after injection. If there is still residual fat under the chin, then I will offer another injection at that time. It certainly does not matter if you wait longer than 6 weeks.  Waiting 2 months or longer between rounds of Kybella is perfectly fine.
