When you look in the mirror or at photos are you one of the many individuals who is bothered by a double chin?  This condition, known as ‘submental fullness’ is extremely common and may be related to weight gain, normal aging, or genetics.  It generally does not disappear fully with weight loss or exercise.  For years, the only treatment was liposuction or a face/neck lift surgery, but now there is a much safer FDA-approved alternative, KYBELLA injection.

What is KYBELLA?

The active ingredient in KYBELLA is synthetic deoxycholic acid.  Deoxycholic acid is a naturally occurring molecule in the body that aids in the breakdown and absorption of dietary fat.  When injected into the fat beneath the chin, KYBELLA destroys fat cells so they no longer can store or accumulate fat.  This reduces fullness under the chin and improves contouring of your chin profile.

What is involved in a KYBELLA treatment?

The treatment is consists of multiple small injections under your chin.  Most patients tolerate the procedure well with very little discomfort.  If desired, prior to treatment, you will sit with topical numbing cream for 15 minutes.  Then the area will be cleansed and marked out in a grid of 10-30 injection sites depending on your chin profile.  After the injections, you will sit with ice under your chin for a few minutes.  Results appear gradually in 4-8 weeks. 

How many treatments will I need?

The number of treatments vary depending on your aesthetic goals.  Most patients receive 2-4 treatments spaced 8 weeks apart and are thrilled with their results.  The number of treatments depends on the amount of submental fullness you have.

What are the side effects?

Side effects are mild and temporary.  The most common side effects are swelling, bruising, pain, numbness, and areas of hardness around the treatment area.  There have been no serious or significant long lasting side effects. 

How will I look after my KYBELLA treatment?

Swelling after treatment is not uncommon and it is important to have 2-3 days where you don’t mind if people see you a little swollen. It is thought that some swelling is desirable as it leads to the lift and tightening effect that improves chin contour along with fat destruction.  Immediately after treatment the area will be slightly red and occasionally bruised.  As fat cells are destroyed over 4 to 8 weeks, you will notice gradual reduction in submental fullness. Most patients see improvements after the first treatment, but a series of 2 to 4 injection sessions are usually needed to achieve the best possible long lasting results.

How long will results last?  Will I need touch ups?

Since fat cells are permanently destroyed by Kybella injections, after your aesthetic goal is achieved, retreatment is not expected.
