A double chin, often referred to as submental fat, is that extra layer of fat that settles beneath your chin, giving your jawline a fuller or sagging look. It can pop up for a variety of reasons, including genetics, weight gain, bad posture, or just the natural aging process, which can make your skin less elastic. A double chin can make your face appear less defined and might even impact your confidence. There are several ways to tackle this issue. Kybella Injections use deoxycholic acid to break down and permanently eliminate fat cells under the chin. If you’re looking for something more immediate, liposuction is a surgical option that directly removes excess fat, giving your jawline a sharper contour right away. For a non-invasive approach, CoolSculpting freezes and gets rid of stubborn fat cells, leading to gradual fat loss. HIFU (High-Intensity Focused Ultrasound) works by tightening and lifting the skin through collagen stimulation, which not only improves jawline definition but also helps reduce mild fat deposits.
