The FDA-approved injectable that permanently destroys fat cells under the chin. Once they're gone, they're gone.
Kybella®
Double Chin & Jawline
What’s going on?
The fullness under the chin is one of the most stubborn spots on the body: often genetic, frequently immune to diet and exercise, and impossible to hide from a side-angle photo. It's also one of the most treatable concerns we see.
Kybella permanently dissolves the fat itself; threads and fillers sharpen the jawline above it. The right answer depends on whether your concern is fullness, definition, or both.

Dissolve the fat, redraw the jaw
The fullness under the chin has one direct answer: Kybella. It’s an injectable that destroys fat cells where it’s placed, and because those cells don’t regenerate, the reduction is permanent. It works over a short series of sessions, each dissolving a portion of the fat, with your body clearing the rest in the following weeks. It treats the fullness itself, not the appearance of it.
The definition problems above the fat belong to a different family. PDO threads redraw the jawline when loose skin, not just fat, is blurring it — lifting tissue back along the jaw and leaving collagen behind as they dissolve. Dermal fillers work by addition instead: strategic structure along the chin and jaw builds the angles that make a profile read as sculpted.
These mechanisms don’t compete, which is why the combination is common. Kybella removes what shouldn’t be there; threads and filler restore the line that should. A double chin is usually some ratio of extra fullness, soft definition, and mild laxity, and each tool answers exactly one of those.
Fullness, definition, or both
The deciding question is what you actually see in the side-angle photo. If it’s a pocket of fullness, Kybella is the answer — permanent, but delivered over multiple sessions with real swelling for several days after each, so it rewards patients who can plan around it. If the jawline has simply gone soft, threads or filler get there faster, with far less recovery, but on a maintenance clock rather than a permanent one.
Budget rhythm follows the same split. Kybella is closer to one-and-done: a defined series, then finished, since the destroyed fat cells don’t come back. Filler is refreshed periodically, and threads’ lift is refreshed as they absorb — smaller, recurring investments instead of one concentrated project.
The consultation is genuinely diagnostic here. A provider feels whether the fullness is fat, laxity, or both, checks how your skin will retract once volume is gone, and sequences accordingly — often Kybella first, definition work after, so the jawline is drawn on the profile you’ll actually keep.
