Beyond the Deep Plane Facelift: The Next Frontier of Facial Lifting

By Dr. Cameron Chesnut, MD | 5 Codes Podcast

I stepped out of the operating room recently thinking about the future of facelift surgery. Not because I had done something experimental or untested, but because a revision case I had just completed illustrated the entire evolution of facial lifting in a single patient: what had been done, what had been missed, and where the field is actually heading.

She was a high-performing, high-standard patient who had sought out a well-regarded surgeon with a strong reputation. The procedure she received was technically competent. The problem was not the execution. It was the paradigm. She had an old-school facelift, and she knew it before she could articulate why. Her exact words in consultation were among the most accurate self-assessments I have ever heard from a patient: "The surface feels tight, but everything underneath is still sagging."

She was right. And the reason she was right points directly to where facelift surgery has been, where it is now, and where it is going.

This post is the clinical companion to our broader piece on what the future of facial surgery actually requires.

A Brief History of How We Got Here

To understand what the next frontier looks like, it helps to understand the progression that brought facelift surgery to this point.

Generation 1: Skin only

The original facelift, over a century old, involved nothing more than tightening the external skin envelope. Pull the skin tighter, suture it in a new position, trim the excess. The results were often dramatic immediately postoperatively but aged poorly because nothing structural had been addressed. The skin stretched back. The telltale "pulled" or "windswept" look that most people associate with obvious facelifts came from this approach.

Generation 2: Skin and the SMAS

In 1974, the superficial musculoaponeurotic system (SMAS) was formally described as a distinct anatomical layer. The SMAS is a fibromuscular sheet that sits beneath the skin and connects to the deeper facial muscles. Incorporating SMAS manipulation into facelift surgery represented a genuine advancement: instead of just pulling skin, surgeons were now repositioning a deeper structural layer. Results lasted longer and looked more natural.

Generation 3: The deep plane

The deep plane facelift takes the dissection beneath the SMAS entirely, working in the plane between the SMAS and the deeper facial structures. This allows release of the key retaining ligaments of the face, including the zygomatic and masseteric ligaments, that anchor soft tissue and resist lifting. By releasing these ligaments, the surgeon can reposition the entire soft tissue unit, including fat pads and muscle, as one cohesive structure rather than pulling individual layers in isolation. The results are more natural, more durable, and better suited to the actual anatomical mechanisms of facial aging.

The deep plane is rapidly becoming the standard. A 2025 systematic review and meta-analysis published in the journal Aesthetic Plastic Surgery evaluated 2,896 patients and found patient satisfaction of 94.4% for deep plane compared to 87.8% for SMAS techniques. It addresses aging the right way: by obeying embryologic cleavage planes and repositioning what has descended rather than simply tightening what sits on top.

But there is a generation four. And that is what I was thinking about in the operating room.

What Comes After the Deep Plane

Even in a thorough deep plane dissection, there is a floor. A deep fascial layer that lies beneath the plane of dissection. And in some patients, particularly those who have already had a previous facelift, or those with more significant structural aging, that floor shows laxity too.

This is the next frontier: recognizing that the deep plane is not the final layer, and that in the right patient, tightening the deep fascial floor of the dissection adds a level of structural support that the deep plane alone cannot provide.

The patient I was revising illustrated this precisely. Her previous surgeon had done what many skilled surgeons do: tightened the exterior envelope, possibly addressed the SMAS, and produced a result that looked like a facelift. But when I was in her revision, working through the deeper layers, the laxity I was seeing was not in the skin or the SMAS. It was at the deepest fascial level. Her surface was tight. The foundation was not.

Addressing that foundation is not a matter of simply going deeper for the sake of it. It requires being able to identify when fascial floor laxity is present, understanding the anatomy of that layer, and knowing how to tighten it in a way that complements the rest of the dissection without creating tension in the wrong places or risking structures that run through those deeper planes.

This is where I think the most meaningful technical progress in facelift surgery is happening right now. Not in new devices, not in energy-based tightening tools, not in threads. In the operating room, with a surgeon working methodically through every layer until every layer that needs to be addressed has been.

Why "Tight on the Outside, Sagging Underneath" Happens

This failure mode has a predictable anatomy. The face ages as a layered system, not a single surface. Gravity acts on every layer independently. The skin descends. The fat pads descend. The SMAS descends. The retaining ligaments stretch. And beneath all of that, the deep fascial architecture that supports the entire structure loses its tension over time.

A facelift that only addresses the skin addresses one of these layers. A SMAS facelift addresses two. A deep plane facelift, done well, addresses three and releases the retaining ligaments that were holding everything down. But if the deep fascial floor has also lost its integrity, none of the layers above it will hold optimally over time regardless of how well the superficial dissection was executed.

This is why my patient felt tight on the surface and saggy underneath. The layers that had been addressed were genuinely tighter. The layer that had not been addressed was not. And because the deeper structure influences how everything above it drapes and holds, the result felt anatomically inconsistent, which is exactly what she described.

Energy-based skin tightening devices, whether radiofrequency, ultrasound, or laser, face the same fundamental problem. They address the skin. Some reach the SMAS. None of them address the deep fascial floor. For patients with early or mild laxity in a single layer, they may produce satisfying results. For patients whose aging is multi-layered, they are addressing the wrong thing.

What This Means in Practice

The practical implication of this evolution is straightforward: any facelift approach that does not address every layer that needs to be addressed will leave some component of aging unresolved. In some patients that is acceptable, because not every layer has significant laxity. In others, specifically those with more advanced structural descent or those presenting for revision, it is the central problem.

My approach in every facelift case involves evaluating all layers of the face during dissection, not committing in advance to stopping at any particular anatomical plane. When I encounter laxity in the deep fascial floor during a deep plane dissection, I address it. When I do not, I do not operate there unnecessarily. The depth of a procedure should follow what the anatomy requires, not what a technique dictates.

This is also why I am cautious about surgeons who describe their facelift approach as a fixed protocol.

The face is not a protocol. The layers are different depths in different patients, the laxity is distributed differently, and the degree of aging is different in every layer for every individual. A surgeon who operates by technique rather than by anatomy will always leave something on the table for the patients whose anatomy does not fit the technique.

The Revision Lens

Revision facelift cases are where these principles become impossible to ignore. When I am revising a previous facelift, I am working through the results of someone else's anatomical decisions. I can see exactly which layers were addressed and which were not. I can see the consequences of each choice, sometimes years later, in how the tissue has aged and held.

The patient in this case was a gift from a teaching standpoint, not because the prior surgery was poor, but because the prior surgery was a representative example of a well-executed procedure within a paradigm that simply does not go deep enough. She showed me everything: a tight surface envelope, a correctly healed SMAS, and an unaddressed deep fascial layer that had continued to descend while the layers above it stayed relatively fixed. The result was a face that felt anatomically incongruent to her, even if she could not articulate the layer-by-layer anatomy of why.

Revision cases like hers are also why I think about facelift surgery as a long-term relationship with the face, not a one-time correction. What I do today creates the substrate for what may need to be revisited in ten or fifteen years. Operating with that long arc in mind, addressing every layer that is showing laxity, using approaches that preserve tissue quality and do not create scar planes that complicate future work, is part of what I mean when I say the goal is to improve someone's aging curve rather than simply reset it.

Frequently Asked Questions

What is the difference between a traditional facelift and a deep plane facelift?

A traditional facelift primarily tightens the skin and may include some manipulation of the SMAS layer beneath it. A deep plane facelift goes further: the dissection proceeds beneath the SMAS entirely, releasing key retaining ligaments of the face that anchor soft tissue and limit how far it can be repositioned. This allows the surgeon to move the entire soft tissue unit, including the fat pads and musculature, as a single cohesive structure. The results are typically more natural-looking, longer-lasting, and better suited to the actual anatomical mechanisms of facial aging. A 2025 systematic review found patient satisfaction rates of 94.4% for deep plane vs. 87.8% for SMAS techniques.

Why does a facelift sometimes make the face look tight on the surface but still saggy underneath?

This happens when the procedure only addresses one or two of the multiple layers that contribute to facial aging. The skin may be tightened, the SMAS may be repositioned, but if the deeper fascial structures beneath the dissection plane still have laxity, the face will continue to drape and descend at the deeper level regardless of how the surface layers are holding. The result is exactly what many patients describe: a surface that looks surgically altered while the underlying structure still communicates age. This is one of the most common sources of dissatisfaction following technically competent but anatomically incomplete procedures.

What is the deep fascial layer in facelift surgery?

The face is composed of multiple layers from the surface inward: skin, subcutaneous fat, the SMAS (superficial musculoaponeurotic system), retaining ligaments, and beneath all of these, a deep fascia that forms the floor of the deep plane dissection. This layer provides foundational support to everything above it. In standard deep plane facelifts, the surgeon works above this floor and does not directly address it. In patients where this layer shows significant laxity, addressing it provides structural support that the deep plane alone cannot deliver.

Why do some facelifts not last as long as expected?

Facelift longevity depends on what was actually addressed. Procedures that only tighten the skin tend to stretch back relatively quickly because skin has limited capacity to sustain tension over time. Procedures that address the SMAS last longer but still leave the deeper layers to continue aging. Deep plane procedures that release retaining ligaments and reposition the entire soft tissue unit provide the most durable results because they address the structural causes of aging rather than its surface expression. A 2025 meta-analysis confirmed significantly higher long-term satisfaction with deep plane techniques. Tissue quality, metabolic health, and post-surgical care also influence how well results hold.

Is a revision facelift more complicated than the original?

Generally yes, for several reasons. Scar tissue from the first procedure creates altered tissue planes that are harder to dissect through. The normal anatomical landmarks may be shifted by the prior work. And in some cases, tissue has been removed or repositioned in ways that limit what can be done in revision. For these reasons, revision facelifts require surgeons with advanced anatomical knowledge, the ability to identify and work through surgical scarring, and the judgment to understand which layers need to be addressed versus which should be left undisturbed.

What should I ask a surgeon about their facelift approach?

The most informative questions center on depth and anatomy. Ask specifically: does the surgeon work in the deep plane? Do they release the key retaining ligaments? How do they approach the deep fascial layer if they encounter laxity there? Do they adapt their technique based on what they find during dissection, or do they follow a fixed protocol regardless of anatomy? A surgeon who can answer these questions in clear anatomical terms, and who describes their approach as anatomy-driven rather than technique-driven, is more likely to address every layer that actually needs to be addressed in your specific case.
