The entry points for fat removal from a double chin are three small holes - one is made under the chin and two behind each ear. These entry sites allow the surgeon to access the fat in the submental area (under the chin) and remove it. These holes heal without stitches.
It's important to note that any cosmetic procedure should be performed by a qualified and experienced professional in a clinical setting. Patients should always have a thorough consultation with their surgeon to understand the risks, benefits, and expectations of the procedure.
