A double chin, often referred to as submental fullness, can be a bothersome concern for many. It’s caused by excess fat accumulation under the chin, and can be influenced by factors like genetics and weight gain. Fortunately, there are effective non-surgical options available. Treatments like HIFU (High-Intensity Focused Ultrasound) and lipolytic injections can help reduce fat deposits, tighten the skin, and improve the overall jawline contour.
