Is one vial of Kybella enough?

The number of vials needed to achieve optimal results is dependent on the initial severity of the sub-mental fullness. You are correct, it typically takes between 1 -2 vials per treatment and I usually recommend 2 to 3 treatments total. With that said I have had some cases where only 1 vial and 1 treatment was needed however, these cases began with a very very small amount of sub-mental fullness. I recommend waiting the 6 weeks and reevaluating with your Physician to determine if you need a second treatment.

The amount of Kybella used should ideally vary from one patient to another and should be customized for the size of the treatment area. Usually a smaller treatment zone (or patient) is going to require less Kybella with each treatment than a larger treatment zone (or patient). Every patient needs at least two treatments, and sometimes as many as 4 or 5 treatments to see the best results.Be sure to see an expert physician injector.All the best,

Thank you for your question about Kybella.
Currently, Kybella is only FDA-approved for submental fat. The amount needed varies from patient to patient.  If your provider used the grid and the correct amount indicated I would trust your provider.  Hope this helps.
