Can Kybella be injected into the lips?

Thank you for your question. There are more effective treatments to increase the volume of the lips, including Juvederm, other fillers and the more permanent treatment of fat injections. Always consult with board certified facial plastic surgeons that are experienced injectors.
Best wishes,

Unless you had prior fat injections into the lips, your lips would not contain fat, even if they were naturally more plump than you would desire. Kybella dissolves fat, so it would not be indicated. Subtle lip augmentation can be achieved using delicate technique and small amounts of Restylane, Juvederm, and Volbella.

I would not suggest that you return to that doctor. Kybella does the exact opposite of increasing plumpness. It dissolves fat under the chin. For your lips, you might want to consider Volbella, a new HA filler specifically designed for the lips.
