I am having mandible chin and jaw surgery done in Febuary. I have the surgery booked combined with a lower facelift. I am 38 and have very minimal sagging now and dont want any loose excess skin after surgery. Is the lower lift something I should do at the time of the mandible surgery or wait until I am fully healed from the mandible? I fear that as the swelling goes down I might end up looking pulled too tight. I am looking for feedback, have it at the same time or wait until healed????
