Hello ! Liposuction can be an effective way to remove excess fat and improve the appearance of the neck and chin area. However, it's possible that you may still have some residual fat or skin laxity that is contributing to the appearance of a double chin. If you have excess skin or loose muscles in the neck area, a neck lift may be an option to consider. A neck lift can help tighten the skin and muscles in the neck area, and can be performed in combination with liposuction to further improve the overall appearance of the neck and chin area. However, it's important to note that a neck lift is a surgical procedure that comes with potential risks and downtime. It's also important to have realistic expectations about the results of any procedure, and to understand that individual results can vary based on a variety of factors, including skin quality, age, and overall health. The best course of action would be to consult with a qualified plastic surgeon who can assess your individual case and provide personalized recommendations based on your unique needs and circumstances. They can also discuss the risks, benefits, and expected outcomes of each option to help you make an informed decision. I hope this helps, best of luck !
