Most people need 2 to 4 sessions for a double chin, spaced at least a month apart. Because Kybella destroys fat cells permanently, once you reach your result you generally do not repeat it.

Kybella is injected deoxycholic acid, a molecule that dissolves the membrane of fat cells under the chin. Those cells are cleared by the body and do not come back, which is why the result is considered permanent for that pocket of fat.

The reason it takes several sessions is that each treatment reduces a portion of the fat, not all of it. A modest amount of submental fullness might resolve in 2 sessions. A larger or fuller area often needs 3 or 4. Sessions are spaced roughly 6 to 8 weeks apart to let swelling settle and to reassess.

Expect swelling. The first several days after each session can involve noticeable puffiness under the chin, which is the treatment working. Some people also feel firmness or tenderness for a couple of weeks.

Kybella suits people with a defined fat pocket and reasonable skin quality. If the main issue is loose skin rather than fat, a tightening treatment is the better conversation. A consultation that assesses fat versus laxity is what determines your real session count.

At Skin Med Spa, Kybella is provided by our board-certified medical team at 960 Warren Ave. in Downers Grove, Illinois. Same-day appointments are available at 630-541-8413, and a consultation is the best way to find out what fits your skin and goals.
