Kybella Swelling Day By Day: 2 Ways To Make It Go Down

Kybella swelling day by day is an after-effect of getting the Kybella injection, the injection is used to treat double chin without having to go through surgery. After the injection, it is normal to feel your chin swelling up days after the treatment, the swelling can last as long as 4 weeks in some people. The swelling is normally a sign that the Kybella injection is breaking down fat cells in your chin. They can go away on their own but you can reduce the length of time as well.


Kybella is a non-surgical procedure that is used to reduce fats under the chin and eliminate double chin. The procedure involves using vials of deoxycholic acid to inject in areas that are targeted. There is no incision made during the procedure.

Fat chins and double chin is one facial feature that bothers a lot of people, this is because it gives the face another shape which may be unbalanced. The American Society for Dermatologic Surgery (ASDS) carried out a survey in 2015 and concluded that about 67 percent of individuals are bothered by excess fat under the chin or neck. To correct this, injections are used. However, the Food and Drug Administration (FDA) currently approved only Kybella as an injectable technique that can be used in treating double chin.

Kybella works by using an artificial form of deoxycholic acid, this acid is produce by the body naturally to help break down and absorb fats. When the synthetic acid in Kybella injections are taken into the skin, it destroys the fat cells under the chin that store fats. When these fat cells are destroyed, fats can no longer be stored and the stored ones are gradually dissolved. Kybella is only used for under the chin.


Swelling of the chin after Kybella injection is a common effect of the injection. The swelling is as a result of your skin having an inflammatory reaction while the deoxycholic acid breaks down fat cells. This swelling is temporary and goes away after few weeks. The swelling can increase as the day goes by, but; it will go away on its own.  If the swelling has open sores and produces foul smell, it may be a sign of infection but if these symptoms are not present, the swelling may be an aftereffect of the injection. 


Kybella treatment is splited into multiple sessions. The number of sessions you get is determined by the amount of fats under your chin. The maximum number of sessions is six treatments. Understanding the entire process from start to finish will prepare you and make your experience go much smoother. Before getting the injection, there are some information you should tell your doctor or health personnel. Information like if you:

  • Are pregnant or plan to become pregnant
  • Are breastfeeding
  • Have bleeding problems
  • Have had or plan to have cosmetic or surgery on your face, neck or chin
  • Are takin blood thinning medications
  • Have swallowing difficulty or any medical issue around or in the neck.

These will help your doctor determine if you are fit for the injection. If you are fit, your doctor examines your neck to target areas for the injection. Multiple small injections are given in different places under the chin, this process will take about 15 to 20 minutes. These side effects are common and fade off on their own after few weeks. If you notice severe side effects that does not seem normal, you should see your doctor or healthcare provider. You can notice your chin swelling up after some days coupled with other side effects like:

  • Stinging or mild pain
