Neck liposuction can be a good option when the fullness is mainly superficial fat under the chin and upper neck, especially if the skin has good elasticity and can tighten after the fat is removed. It is often used for people who have a genetic double-chin/full-neck pattern that does not improve much with weight loss. In your side-view photo, there appears to be fullness under the chin and a softer neck-chin angle. A photo cannot show whether that fullness is mostly superficial fat, deeper fat, muscle position, salivary glands, skin laxity, or chin/jaw projection, and those details determine the right treatment. If the issue is mostly superficial fat, submental/neck liposuction may improve the contour. If there is deeper fat under the platysma muscle, a low hyoid bone, prominent digastric muscles, enlarged glands, loose skin, or a small/retrusive chin, liposuction alone may give only a partial improvement. In those cases, options may include deep neck contouring, platysmaplasty, skin-tightening procedures, or chin augmentation depending on the exam. The most important step is an in-person evaluation by a board-certified plastic surgeon or facial plastic surgeon who does a lot of neck contouring. Ask specifically whether the fat is superficial or deep, whether your skin is likely to retract well, whether your chin position contributes to the profile, and what result is realistic with liposuction alone. If you are a good candidate, neck liposuction is usually a relatively focused procedure, but it still has risks such as swelling, bruising, unevenness, numbness, contour irregularity, loose skin, and the need for revision. The best plan should match the anatomy rather than assuming all neck fullness is just fat.
