How much swelling is expected with 1 vial of Kybella?

swelling is expected with kybella, it is due to the fat cells dissolving on contact with the product and leading to inflammation and fluid.   It is thus not quantifiable and depends on amount of fat that reacts, and the inflammation that your body produces.   If you had three vials before, then doing 1 should be less swelling than what you had before.

You should have less swelling with subsequent treatments as there should be less fat in the area.  Remember that numbness, swelling, tenderness and hardness are all expected, temporary side effects.  Good luck with your future treatments! 

The degree of swelling varies from patient to patient. Most patients need 2-3 treatments. Your surgeon can recommend if additional treatment is needed or not based on your current results and your aesthetic goals.
