Thanks for a simple, but very important, question regarding facelifting. Having performed almost 6,000 lower facelifts and necklifts over the past 11 years, I would say with 100% certainty that this lift must have a muscle tightening component. The platysma and SMAS layer (the jawline muscle layer) should be tightened internally in every lift. In my opinion, this is what gives most of the result, along with longevity to the lift. Of course, there is excess skin that is removed, but the workhorse of the lift should be on the internal muscles. This always should occur from the sides of the face (around the ears). Sometimes the muscle under the chin needs to be tightened as well, usually as the discretion of the surgeon.The easiest way to find out if your surgeon tightens the muscle is to just simply ask! It is a completely reasonable, and common, question. Good luck!!!-Doc L.
