The popular story of facial ageing is a story about lines. A line appears, the line is treated, the face looks younger. It is a clean narrative, easy to sell, and incomplete in almost every clinically meaningful way. The face does not age primarily on its surface. It ages structurally, across at least five tissue layers, over decades. Wrinkles are the last and most superficial expression of changes that began much earlier in bone, fat, ligament and the dermis itself.
Treating only the surface tends to produce a recognisable result: a forehead that no longer moves on a face that has otherwise lost its underlying support. Restoring the appearance of youth is not the same problem as smoothing the skin, and conflating the two is one of the most common reasons cosmetic outcomes age poorly.
The myth
Ageing is what you see in the mirror: lines, creases, crow's feet. Treat the lines, treat the ageing. Anything beyond that is upsell.
The reality, in five layers
Anatomical and imaging studies, including serial CT and MRI work from craniofacial surgery, consistently describe facial ageing as a multi-tissue, multi-decade process. Five interacting layers are involved, and they change on different timelines.
1. Bone
The facial skeleton remodels throughout adult life. The midface, orbital rim and mandible all lose volume and projection. Orbital aperture widens, the maxilla recedes, and the chin loses anterior projection. Skin and soft tissue that used to drape over a fuller skeleton now drape over less, contributing to the appearance of sagging even when the soft tissue itself is healthy.
2. Deep and superficial fat compartments
Facial fat is not a single sheet. It is organised into discrete compartments that lose and shift volume at different rates. The deep midfacial fat tends to atrophy, which removes structural support for the overlying tissue. Superficial fat in the cheek and jawline can hypertrophy in some patients while atrophying in others, producing the characteristic heaviness of the lower face combined with hollowing of the upper face.
3. Retaining ligaments and SMAS
The retaining ligaments of the face attenuate over time, and the superficial musculoaponeurotic system (SMAS) descends. This is why a tired-looking face is not always a thin or wrinkled face. Ligament laxity allows tissue to migrate inferiorly, deepening folds at the nasolabial and labiomandibular junctions.
4. Skin quality, including pigment and vasculature
Within the skin itself, ageing is more than wrinkles. Dermal collagen and elastin decline, the basement membrane flattens, microvasculature thins and pigmentation becomes uneven. Photoageing, driven primarily by ultraviolet exposure, is responsible for an estimated 80 per cent of visible facial ageing in lighter skin types, according to long-running dermatology literature. Telangiectasia, solar lentigines and a sallow tone often appear before significant wrinkling.
5. Dynamic and static rhytides
Lines themselves come in two forms. Dynamic lines appear with muscle movement. Static lines are visible at rest because repeated movement, plus loss of underlying support, has etched a crease into the dermis. The two respond differently to treatment, and treating a static line as if it were dynamic is one of the more common reasons a result disappoints.
A face does not age in one place. It ages in five, simultaneously, on five different clocks.
Why this matters clinically
If the model of ageing is incomplete, the plan that follows is incomplete. A patient whose primary change is midfacial volume loss does not need more neuromodulator. A patient whose primary change is skin quality does not need more volume replacement product. A patient whose underlying issue is ligament laxity may not be a candidate for any non-surgical intervention at all, and the most honest answer at consultation is to acknowledge that and refer.
The opposite mistake is equally common. Faces that have been treated only at the surface, year after year, can develop an over-treated appearance with no underlying support: smooth skin on a face that has hollowed at the temples, lost cheek projection, and lengthened at the chin. The original lines are gone. The face still does not look refreshed.
What a layered assessment looks like
- · Static assessment of bony landmarks, including orbital rim, malar projection, mandibular angle and chin projection.
- · Dynamic assessment of muscle activity at rest and on animation, looking for compensatory patterns.
- · Mapping of volume change across the deep and superficial fat compartments, not just where the patient sees a line.
- · Assessment of skin quality: pigment, vascular pattern, texture, pore size, hydration and elasticity.
- · Recognition of ligamentous descent and its role in the lower face, which often cannot be fully addressed without surgical input.
A more honest treatment philosophy
Approaches sometimes described as regenerative aesthetics prioritise the deeper biology before the surface. The order matters. Skin quality and dermal health are protected and improved first, structural support is considered next, and superficial line treatment sits at the end of the conversation, not the start. Categories that may be considered, always under medical assessment, include bio-remodelling and bio-regeneration treatments for skin and dermal quality, volume replacement treatments used conservatively to restore lost compartments rather than fill lines, calcium hydroxylapatite or poly-L-lactic acid biostimulators for selected indications, and energy-based devices for skin tightening.
Wrinkles still belong in the plan. They are simply not the plan.
What to ask at consultation
Useful questions, before any treatment, are: which layer of my face is changing most? Is what bothers me actually a skin issue, a volume issue, a structural issue, or some combination? What can be improved with non-surgical care, and what cannot? A practitioner who can answer these clearly, and who can decline a treatment when it would not address the underlying problem, is practising the kind of medicine the AHPRA cosmetic guidelines envisage.
