What Causes a Double Chin?

Few things ruin your profile like submental fullness, or extra fat under your chin. With too many fat cells in your under-chin area, you get the unwanted double chin. That can make you look heavier and older than you really are because it’s such a highly visible spot on your body.

That’s why Elaine Phuah, DO, MBA, FACOI, offers Kybella® — an injectable treatment to eliminate those fat cells — to her patients at Hanami Medspa in Fort Worth, Texas. With this treatment, you can directly target the fat cells that are causing your excess chin volume.  

But for now, if you’ve got a double chin, you’re probably wondering how it got there. Here are four causes that could be to blame. 


Unfortunately, double chins run in the family. 

Family members with submental fullness put you at a greater risk for getting a double chin yourself. 


If you look in the mirror, you can probably adjust your neck so that your double chin gets bigger or smaller. In other words, the way you hold your head plays a role in the prominence of your double chin. 

Make an effort to improve your posture and you should see your double chin reduce. Ideally, you want to hold your head up straight with your chin pointed slightly down.  


As you get older, your skin loses its elasticity. Drooping skin underneath your chin can make a double chin seem bigger. 

If you’ve noticed your double chin worsens as the years pass because your skin is sagging, talk to Dr. Phuah about noninvasive, no-downtime skin tightening treatment


Because excess fat cells cause a double chin, it should come as no surprise that extra weight contributes to submental fullness. Losing extra pounds can make a huge difference in the size of your chin.

Treating a double chin

All this said, you don’t have to perfect your posture or shed weight to get a slimmer profile. With Kybella, Dr. Phuah can inject an FDA-cleared solution specifically formulated to destroy the fat cells under your chin. 

This treatment comes with no downtime (although you might have some bruising in the treatment area) and only takes about 20 minutes. In the weeks that follow your Kybella treatment, your body processes out the now-destroyed fat cells, leaving you with a more sculpted chin.

You might need a few Kybella treatments to reach your ideal profile. Talk to Dr. Phuah so she can customize a treatment plan for you. 

Don’t let your double chin define your appearance. To get started with Kybella, call Hanami Medspa or make an appointment online today.
