Facial ageing is often first noticed as fine lines, a softer jawline, changes in facial volume, or a more tired appearance. These visible changes develop because the skin, fat, muscle and bone are each changing over time, often at different rates.
Understanding these layers is useful before considering treatment. It helps explain why the same procedure can suit one patient but not another, and why an assessment should identify the tissue changes responsible for the concern before a recommendation is made.
From the surface inward, the main layers are the skin, facial fat, muscle and supporting structures, and bone. Each contributes differently to facial shape and skin quality, and each has its own pattern of ageing.
With age, the dermis gradually loses collagen and elastin and may become thinner and less resilient. Patients may notice fine lines, crepiness, reduced elasticity and a change in the way the skin reflects light.
Skin ageing includes both intrinsic and extrinsic influences. Intrinsic ageing is related to time and genetics, while extrinsic ageing is strongly affected by environmental exposure, particularly ultraviolet radiation. A randomised trial found that daily sunscreen use produced measurable protection against skin ageing, supporting photoprotection as an important modifiable step.
Topical retinoids also have substantial clinical evidence in photodamaged skin. Multicentre, double-blind studies conducted over 48 weeks reported repair of sun-damaged connective tissue.[2]
Facial fat is arranged in distinct superficial and deep compartments rather than as one continuous layer. These compartments support the face in different ways and do not all change uniformly with age.
The deeper compartments contribute structural support, while the superficial compartments influence surface contour.[3] A change in one compartment can therefore create a different appearance from a similar change elsewhere.
Imaging studies suggest that facial fat does not simply disappear. Magnetic resonance imaging of the midface found reductions in volume and thickness across several superficial compartments, together with an increase in a lower compartment that was consistent with displacement. A computed tomography study similarly reported reductions in upper and middle compartments with an increase inferiorly, supporting a pattern of redistribution.[5]
This has practical implications for treatment planning. If facial fat has both reduced and shifted, adding volume directly beneath every visible hollow may not reproduce the original contour. The position of the remaining tissue is considered alongside the amount of volume loss.
Fat compartments also respond differently when volume is added. Cadaveric volumetric analysis found variation in the surface change produced across compartments, with the sub-orbicularis oculi fat compartment showing a particularly high surface-volume coefficient.[6] This is one reason placement and dose are tailored to anatomy.
Repeated facial movement contributes to dynamic lines such as frown lines, forehead lines, and crow’s feet. Over time, changes in muscle tone, resting position, retaining ligaments, and other fibrous structures also influence where the soft tissues sit.
Facial descent is therefore not caused by loose skin alone. It reflects the interaction between the supporting structures and the fat compartments they separate.
The facial skeleton continues to remodel during adult life. Changes in the orbital rims, maxilla, and mandible alter the underlying framework that supports the soft tissues.
As this framework changes, the overlying tissue may appear less well supported. In some patients, an appearance described as sagging partly reflects changes in the structures beneath the skin rather than a change in the skin alone.
This helps explain why a treatment directed only at skin quality may not fully address a concern that is being driven by deeper structural change.
Treatment is generally most effective when it is matched to the layer contributing to the concern. A procedure can work as intended yet provide limited visible benefit if it is addressing a different tissue problem.
Skin-quality treatments are intended to improve hydration, texture, or pigmentation. Treatments that work on deeper tissues may help improve skin laxity, but they do not directly treat surface concerns such as pigmentation or sun damage. Similarly, volume-restoring treatments can improve facial contours but are not designed to tighten loose skin. Each has a defined role and a defined limit.
Many patients experience changes in more than one layer. Consensus recommendations therefore discuss how aesthetic modalities may be sequenced or combined rather than applied in isolation.
The following overview describes the general role of each treatment category. Individual suitability still depends on examination and medical assessment.
Photoprotection and retinoids have a strong evidence base for photoaged skin. Where appropriate, treatments directed at the dermis, including intradermal hyaluronic acid and resurfacing procedures, may support hydration, texture and pigmentation rather than structural repositioning.
Volume restoration can support areas of deficit, but placement is guided by anatomy rather than by the visible hollow alone. Because facial compartments respond differently, the same amount of product can produce different surface changes in different locations.[6] Product properties also influence how a gel resists deformation and spreads through tissue.
Energy-based treatments directed at deeper layers create controlled thermal effects that initiate collagen remodelling, with results developing gradually over the following months. Studies of microfocused ultrasound with visualisation have examined its effects on skin physiology and laxity, while expert consensus supports adapting treatment to the individual rather than using a fixed protocol.
These treatments also have limits. Significant excess skin or advanced tissue descent may require surgical assessment, and non-surgical options should not be presented as equivalent where they cannot provide the same degree of correction.
Skeletal change cannot be reversed non-surgically. In selected cases, carefully placed volume may compensate for reduced projection, but this is an approximation and requires conservative planning to avoid an overfilled appearance.
Several practical principles follow from this layered understanding of facial ageing.
A facial assessment aims to identify which layers have changed, how much each one contributes, and which change is most closely related to the patient’s concern.
At VIDASKIN, treatment planning follows this assessment rather than a fixed menu. The recommendation may involve skincare, a procedure directed at a particular layer, a different option from the one initially requested, or no treatment at that stage.

Changes in the skin, facial fat and supporting structures occur gradually and may begin before they are visibly noticeable. The timing and distribution vary considerably, so assessment is generally more informative than age alone.

It can be caused by several changes. Skin laxity may contribute, but facial fat redistribution, changes in retaining structures and skeletal remodelling can also reduce soft-tissue support and alter facial contour.
Some aspects can be influenced. Ultraviolet-related skin ageing can be reduced through regular photoprotection, and a randomised trial found measurable benefit from daily sunscreen use.[1] Intrinsic ageing and skeletal remodelling cannot be prevented in the same way.
The treatment may have been addressing a different layer from the one driving your concern. Because each procedure acts on particular tissues, a result that suits one patient’s pattern of ageing may not suit another’s.
