At a glance: why does the face change with age?
Facial aging involves the relationship between skin, fat, muscles, supporting ligaments and the facial skeleton, and it does not happen the same way in every region. During assessment, I separate surface changes from changes in volume or tissue position before proposing treatment. A photograph of a tired-looking face is not enough to tell which operation would make sense.
- Surface: spots and texture need skin care; a facelift does not treat everything on the skin.
- Volume: some areas hollow while others gain volume; fat grafting is used only where it is indicated.
- Support: ligaments link the skin and the SMAS to deeper layers, differently in each region.
- Evidence: a review of 54 studies found conflicting data and few studies following the same people over time.
- Consultation: you point to what bothers you; the examination, including your face in motion, shows the cause.
My deep plane facelift guide explains the operation and how I plan it. This article takes a step back: how I organize the assessment so that the proposal responds to what bothers you, rather than treating every change as the same problem.
You might notice a shadow below an eye, fullness near the jaw or a less distinct transition into the neck. All three can be described as looking older, yet they are different concerns. You do not need to name a ligament or memorize fat compartments before seeing me; a basic understanding of anatomy simply helps you ask more useful questions.
Four questions that organize the examination
Is the concern on the surface?
Tell me whether you mean a mark, texture or another feature of the skin. I do not present a facelift as the answer to everything visible on the surface.
Is it about volume?
A hollow under the eye and a bulge nearby can coexist. Before adding or removing tissue, I need to find the area responsible and see how it relates to its surroundings.
Is it about contour or position?
Your jawline can look less defined even if your face has not become thinner. I assess how the tissues are distributed and how they relate to each other, rather than reading every change as missing fat.
What happens when you move?
I also want to see your expression when you talk and smile. Planning cannot be based on a still face alone, and the features you want to keep belong in the discussion.
Facial anatomy is not a stack of identical layers
A diagram of skin, fat, muscle and bone makes a first explanation easier, but it suggests a uniform arrangement that does not match every region. The tissues around the eyelids are not organized like those in the neck.
A 2024 anatomical study dissected the heads of 30 adult cadavers aged 60 to 78 and described differences between the facial ligaments: the zygomatic ligament has fibers inserting directly into the skin, while the masseteric and mandibular ligaments connect to fascia and the SMAS [1]. It helps explain these relationships, but it did not follow the same people as they aged or compare surgical results.
I use anatomy to explain a proposal, not to turn a diagram into proof that one treatment suits everyone. The useful question is what a finding means for your examination.
Why gravity or fat loss alone rarely explains it
A 2025 review included 54 studies of age-related facial change. The authors found conflicting data, generally low levels of evidence and few studies following the same individuals over time. Even so, they noted that the facial skeleton remodels rather than simply shrinking, that some fat compartments enlarge and not all of them shift, and that the retaining ligaments are firm structures [2].
That does not justify the opposite oversimplification, that facial fat never loses volume or that no structure changes position. The review challenges models; it does not give an individual diagnosis or show that one operation suits everyone.
In practice, you do not have to fit your concern into a single theory. Two people can point to the same area and still have different needs and options.
Skin, volume and contour need different goals
If your main concern is a mark on the skin, I need to know that before discussing a procedure meant to change contour. A photograph with smoother skin does not show that a facelift addressed the concern you have.
When volume is part of the discussion, I want to identify the area and the purpose. Facial fat grafting may be part of the plan, but adding fat should not be justified by a vague promise to restore youth. The article on how much grafted fat remains explains why volume cannot be reduced to a guaranteed percentage.
Contour raises another question: what is creating the feature you point to? “Double chin” can describe very different situations, so I prefer to examine the area before you commit to a technique chosen from a photograph or a name online.
Where SMAS and platysma fit in
SMAS stands for superficial musculoaponeurotic system, the layer just beneath the fat under the skin. The platysma is a thin neck muscle that extends into the lower face. These terms come up when discussing the planes treated in a facelift.
I do not expect you to choose an operation from those definitions. I would rather explain what I propose to treat, why it relates to your priorities and what the risks are. My face procedures page lets you explore each topic in more depth.
When the neck is part of the plan, deep neck surgery is usually performed together with a facelift; on its own, only in rare, carefully selected cases after an assessment. That matters if you are looking only for neck surgery.
The eye area needs its own assessment
Someone who says their eyes look tired may mean the eyelid, the brow or a shadow beneath the eye. I ask you to show me the feature instead of treating those descriptions as synonyms.
For the lower eyelids, I ask three questions: is there excess skin, bulging fat or a hollow? My lower blepharoplasty page explains how I treat each one: I remove the excess fat and, for deep under-eye hollows, use nanofat.
I also ask what you want to preserve. A fear of losing a familiar expression deserves as much attention as the anatomy.
Bring photographs as information, not a template
An older photograph can help you show what feels familiar or what has changed. I do not use it as a promise to recreate your face at an earlier age.
Tell me when the change bothers you: in profile, on video calls or under a certain light. I cannot identify a structure that needs surgery from a shadow in a single picture.
Photographs taken at my practice record the assessment and follow-up in a standardized way. The patient journey shows how those visits are organized before and after surgery.
How I turn the assessment into a plan
I begin by listening, examining and matching the findings to the priorities you described. From there, I build the surgical plan, explain each component, show cases and leave time for questions.
You should be able to say why each step was proposed. If we combine procedures, each one needs a clear purpose; the fact that several procedures appear on this website does not mean they all belong in your operation. Before deciding, it helps to think about four points:
- Which change is my priority, and which is a secondary wish?
- What does the proposed plan treat in each area?
- Which limits and risks should influence my decision?
- How will I organize preparation, recovery and follow-up?
If you live outside Brazil, we can start with a video consultation, but the plan is confirmed in person before surgery.
Questions
Can anatomy diagrams tell me which surgery I need?
No. They help explain concepts, but they cannot replace an examination and individual planning. I do not expect you to arrive with a surgical indication based on an online illustration.
Does a thinner-looking face mean I need fat everywhere?
Not necessarily. I need to find where the concern is and what makes sense overall. If I propose grafting, we discuss the specific areas, limits and follow-up rather than treating volume as the answer to every change.
Does a deep plane facelift treat every sign of aging?
No. I connect your priorities with the proposed procedure and explain what it will not address. This matters even more when you have concerns about skin, eyelids and neck at the same time.
What if I do not know the right medical words?
Tell me what you see and what bothers you. “I want to understand this change near my jaw” is a good starting point; I can explain the anatomy during the assessment.
Let’s make the changes easier to understand
Write down the two or three changes that matter most and anything you want to preserve. Then write to us on WhatsApp: Bruna, my AI assistant, handles the first contact and then puts you in touch with Isanna to arrange a consultation with me.
