If you lose weight after liposuction of the chin or neck, usually you're safe within five or 10 pounds here or there. But if you lose a significant amount of weight and you're the type of person who stores a lot of fat in this area due to genetics, then you might notice some increased skin laxity. However, in Dr. Hakimi’s experience, this is more of a problem after a facelift rather than liposuction because there will not be much fat left. We leave a very tiny amount of fat just to keep the skin looking healthy, natural and youthful.
