A UK paper called me on a Friday afternoon last week for a quote on a public figure whose face had been the subject of a thousand “what did she have done” comments online. The reporter wanted a technical read. She had already spoken to a colleague of mine, Dr. Douglas, who had focused on the lower half of the face. She wanted to know whether I agreed.
I did. Not because I had any inside knowledge of the patient. Because the lower third of that face was the part of the face that had changed, and the change was readable from the photographs.
Every plastic surgeon has had this exact conversation a thousand times in private, across a desk, with a real patient sitting on the other side of the desk asking about a feature that is not actually the feature that needs the work. The features the patient points to are almost always the upper or middle third. The eyes. The brows. The cheekbones. The features the surgeon wants to talk about are almost always in the lower third. The jawline. The cheek pad. The perioral region. The chin.
So let me write the long version of why. Not for the celebrity story. For the patient.
The Three Thirds, and What Lives in the Lower One
The face divides into three horizontal thirds. Upper, hairline to brow. Middle, brow to base of nose. Lower, base of nose to chin. Each third ages on its own clock. Each third answers to different operations. Each third tells the surgeon something different.
The lower third holds the jawline border, the jowl, the prejowl sulcus, the labio-mandibular fold, the marionette region, the corner of the mouth, the perioral skin, the chin, the submental fat pad, the platysma, and the cervicomental angle. The cheek pad, anatomically a midface structure, drops down into the lower third as the supporting ligaments lengthen and is therefore best read together with what is happening below it.
The lower third is the integrator. Almost every change in the upper and middle thirds eventually shows up in the lower third. Volume loss in the midface drops into the marionette region. Skin laxity above the jaw drops into the jowl. Loss of mandibular definition takes the line that the eye reads as “young” and erases it. A small chin makes the whole lower face look heavier than it is.
The features a patient points to in the mirror are the noise. The lower third is the signal.
The Five-Minute Read Across the Desk
When I sit across from a new patient, the read happens in the first five minutes, before the patient has finished telling me what she came in for. The order goes roughly as follows.
The mandibular border, angle to chin. Clean line, or interrupted by a jowl that has migrated forward and down over the bone.
The cheek pad position. Sitting high on the zygoma, or slid forward and down into the upper lower third.
The perioral region. Lip volume, vermilion border, philtrum, upper lip length, dental show in repose, dental show in animation, corner of the mouth, marionette.
The chin and the cervicomental angle. Projection in profile. Submental fullness or laxity. Platysma. The line between face and neck.
That read is what shapes the next forty minutes of the consultation. If the patient came in to discuss her cheekbones and the read says the lower face has dropped, we are going to spend the next forty minutes on the lower face, because that is the conversation that produces a plan that matches her actual face.
The Five Forces That Change the Lower Third
There are five primary drivers of change in the lower third, and most patients have more than one of them in play.
Bone resorption. The mandible and the maxilla both lose bone with age. The lower jaw narrows. The chin recedes a few millimeters. The soft tissue above the bone has more space to drift.
Ligament lengthening. The retaining ligaments that hold the cheek pad to the zygoma and the jowl out of the mandibular border lengthen over decades. The soft tissue slides down the rails.
Volume loss. Deep fat compartments shrink unevenly. The midface flattens. The nasolabial fold deepens. The corner of the mouth turns down because the structures behind it have lost volume, not because the patient is unhappy.
Skin laxity. Collagen and elastin both decline. The dermis thins. The skin loses its grip on the underlying structures and starts to read the shape of whatever has moved.
Weight change and prior treatment. Significant weight loss, especially the rapid loss now common with the GLP-1 medications, can age a lower third by a decade in eighteen months. Years of poorly placed filler can create a lower face that reads heavier than it would have aged on its own. I see both of these often enough now that they deserve their own line in the read.
The Operation That Addresses the Lower Third Best in 2026
For most patients with a dropped cheek pad, an early jowl, and a marionette region that has lost its definition, the right operation in 2026 is a deep plane facelift. The deep plane lifts the cheek pad back to the zygoma, repositions the jowl behind the mandibular border, and restores the line that the eye reads as “young.” It does not stretch the skin to do the work. It moves the deeper structures back to where they used to live and lets the skin redrape.
I trained the deep plane facelift the long way around. Mayo Clinic plastic surgery fellowship, then the Ponytail Academy intermediate course in Pittsburgh and the advanced course in Santa Monica, then years of doing the operation. The “facelift won” debate is over. The debate now is how deep, how wide, on whom, and through which access. The answers depend on the lower third.
When a paper or a website asks a surgeon to read a public figure’s face, the answer is usually written in the form of “she had X.” Filler, threads, deep plane, deep neck lift, buccal fat removal, chin implant. The shortcut sells better than the longer answer.
The longer answer is that the change you are reading on a public figure’s face is almost never one thing. It is almost always a combination of things, layered over years, sometimes with a real operation in there, sometimes without, sometimes with a weight change or a hormonal change or a hair change that contributes more than any procedure on the list. Telling the difference from a press photograph is hard. Telling the difference from across a desk in a consultation room, with the patient’s photographs from a decade earlier and the chance to put hands on the face, is easy.
That is why I take the call from a reporter when one comes, and that is why I am careful with my answer. The technical read is fair game. The diagnosis of “she had X” is not.
What I Will Not Do
I will not chase the cheekbone with filler in a face whose lower third has dropped. That makes the lower face look heavier, not the upper face younger.
I will not place a filler pillow under a marionette fold that needs the jowl repositioned.
I will not augment a chin that needs the soft tissue above it moved, not added underneath.
I will not perform a facelift on a patient whose ligaments are still intact and whose lower face is still well-defined, because that patient does not need one yet.
The honest consultation starts with the honest read. The honest read starts with the lower third.
Ready to Talk?
If a facial procedure is on your mind and you are not sure where the conversation should start, the conversation should start with the lower third. We will read it across the desk, set it next to the rest of your face, and build a plan that matches the face in front of me, not the feature you walked in to ask about.
