How Aging Affects Facial Fat Compartments
Facial aging isn’t just about sagging skin – it’s about changes beneath the surface. Over time, fat compartments in the face shift, lose volume, or expand, creating visible signs of aging like hollows, folds, and sagging. Here’s a quick breakdown:
Deep fat compartments shrink with age, reducing structural support.
Superficial fat compartments may expand or sag, leading to jowls and folds.
These changes cause features like hollowed cheeks, deeper nasolabial folds, and a less defined jawline.
Treatments that target specific fat compartments, like dermal fillers, help restore volume and balance. Combining fillers with other techniques, such as skin treatments or neurotoxins, can address both structural and surface-level aging for a natural look. Clinics like Calista Aesthetics use precise methods to achieve these results, focusing on individual needs without overfilling or creating an artificial appearance.

Superficial vs. Deep Fat Compartments
Superficial Fat Compartments
Superficial fat sits just beneath the skin in small, mobile lobules, closely linked to facial muscles. This layer includes compartments like the nasolabial fat, superficial medial cheek fat, middle cheek fat, and infraorbital fat. Together, these areas help create the soft and smooth contours of the face.
Interestingly, research involving 20 healthy women revealed that older participants (ages 60–70) had more superficial cheek fat compared to younger ones (ages 16–30). This increase or shifting of fat can lead to unwanted fullness in areas like the jawline, altering the face’s overall appearance.
Deep Fat Compartments
Deep fat compartments are located beneath the facial muscles in Layer 4, where they are tethered to the bone. These include the sub-orbicularis oculi fat (SOOF), deep medial cheek fat (DMC), and the buccal fat pad. Unlike superficial fat, these deeper compartments act as the face’s structural foundation, supporting and shaping its midface projection.
While superficial fat defines the face’s contours due to its mobility, deep fat remains relatively immobile and firmly anchored. Composed of larger, loosely arranged lobules, deep fat is more prone to compression against the bone, which accelerates its loss over time. A study following patients for ten years (ages 46 to 57) found that deep fat volume decreased by 18.4%, compared to an 11.3% reduction in superficial fat [3].
“Selective deflation of the deep fat pads with age leads to loss of support and descent of the overlying superficial fat, thereby contributing to the ptotic appearance of the aging face.”
Dinah Wan, MD
This difference in fat loss and redistribution between the layers contributes to the distinct changes in facial appearance as we age.
How Changes in Both Layers Affect Appearance
The interaction between superficial and deep fat compartments plays a critical role in the visible signs of aging. When deep fat diminishes, it loses its ability to support the overlying superficial fat. This often leads to pseudoptosis – a sagging effect caused by volume loss rather than gravity alone.
As deep fat decreases, superficial fat begins to shift, which can deepen facial folds. For example, the loss of volume in compartments like the DMC and SOOF contributes to more pronounced nasolabial folds and tear-trough deformities. At the same time, superficial fat may accumulate in the lower face, creating what’s known as the “Pyramid of Age” appearance.
Recognizing these changes helps clinicians design injectables and skin treatments that address both structural support and balance. These compartment-specific shifts are key to understanding the regional aging patterns discussed later.
How Aging Affects Different Facial Areas
As we age, the changes in facial fat compartments – both superficial and deep – manifest differently across various regions of the face. Each area undergoes unique transformations that contribute to the overall aging process.
Temples: Volume Loss and Hollowing
The temples are among the last areas to experience fat loss, but the effects are still noticeable over time. The lateral temporal cheek fat, a superficial compartment, gradually diminishes, leading to hollowing that disrupts the natural facial contour [2].
“Clinical trends show that the periorbital and malar fat pads tend to be affected first in life, followed by the lateral cheek, deep cheek, and lateral temporal areas.”
Dinah Wan, MD, Department of Plastic Surgery, University of Texas Southwestern Medical Center [2]
This sequence of fat loss highlights the importance of timing when addressing volume restoration in the temples. Since the temples are affected later than other areas, treatments here may require a different approach compared to the midface or cheeks.
Midface and Cheeks: Fat Loss and Sagging
The midface is one of the areas most visibly affected by aging. A 2021 CT study involving 19 participants revealed a 12.2% reduction in midface fat, with deep fat compartments losing 18.4% and superficial fat shrinking by 11.3% [3].
As deep medial cheek fat diminishes, it removes the structural support for the overlying superficial fat. This causes the superficial fat to shift downward and inward, leading to deepened nasolabial folds and hollowing below the tear trough. These changes create a distinct V-shaped deformity in the midface [4][1].
“In particular, we think that deep facial fat loss removes support from the overlying fat. That causes deepening of the nasolabial fold, which runs from the nose to the mouth. Meanwhile, fat loss closer to the surface makes the cheeks appear deflated.”
Dr. Aaron Morgan, Medical College of Wisconsin [3]
The loss of volume in the cheeks results in a flattened, less youthful appearance, often described as losing the “apple” shape of the cheeks. In cases of rapid weight loss, this effect becomes even more pronounced. One study found that 88% of patients who experienced significant weight loss showed hollowing in the midface and nasolabial folds [5]. These changes underscore the need for targeted treatments, such as dermal fillers, to restore volume and support in specific areas.
Lower Face and Jawline: Fat Redistribution and Jowls
The aging process in the lower face follows a different pattern compared to the midface and temples. Instead of losing volume, areas like the jowls and submental region (under the chin) experience an increase in fat volume, known as hypertrophy [2].
As deep fat support diminishes, superficial fat begins to descend and accumulate along the mandibular border, leading to the formation of jowls. The mandibular septum acts as a boundary for this descended fat [6]. These changes result in a blurred jawline and contribute to the characteristic sagging seen in the lower face [2].
Fat Layer | Aging Effect | Impact on Jawline |
|---|---|---|
Superficial Fat | Hypertrophy and descent | Adds to jowl formation and blurs jawline |
Deep Fat | Atrophy and loss of support | Leads to sagging and structural changes |
Addressing these transformations requires a combination of techniques that target both the redistribution of fat and the restoration of foundational support. These tailored strategies aim to redefine the jawline and improve overall facial harmony.
Treatment Options for Age-Related Fat Changes
Restoring Volume with Dermal Fillers
One of the most effective ways to address age-related fat changes is by targeting specific deep fat compartments for precise volume restoration. Think of these compartments as a “GPS” guiding treatment. For instance, augmenting the deep medial cheek restores forward projection and naturally softens the nasolabial fold by rebuilding the structural foundation. Similarly, injecting just above the periosteum in the medial sub-orbicularis oculi fat (SOOF) smooths the lid-cheek junction and helps conceal the visible orbital rim [1]. Deep lateral cheek augmentation bridges the gap between the anterior and lateral cheek, addressing the hollowing that often develops in this area.
“Rather than masking the creases of facial aging with superficial multilayering of fat in nonspecific malar regions, we propose that the direct augmentation of specific deep cheek compartments creates a more natural look.”
Dinah Wan, MD [2]
Different types of fillers are chosen based on their unique benefits. Hyaluronic acid fillers provide volume and hydration lasting 6–12 months, while poly-L-lactic acid stimulates collagen production for longer-lasting results – up to two years or more [8].
For lip enhancement, injecting into the deep perioral compartment (behind the orbicularis oris muscle) creates a natural eversion and highlights the wet-dry junction. This approach avoids the overfilled, artificial look that can happen with superficial injections [7].
These targeted techniques can be even more effective when paired with treatments that relax muscles or refine the skin’s surface.
Additional Treatments for Better Results
While dermal fillers tackle volume loss, neurotoxins like Jeuveau and Dysport help by relaxing muscles responsible for dynamic wrinkles. The popularity of botulinum toxin treatments surged by 537% between 2000 and 2008, demonstrating how well these procedures complement one another [7].
Skin-refining treatments like microneedling with PRP or Rejuran improve texture and tone, enhancing the skin’s overall appearance. Chemical peels are another great option for refining the skin’s surface. This combination of treatments embodies a “lift and fill” philosophy, which emphasizes not just volume restoration but also improving the quality of the overlying skin [1].

Conclusion
Key Points About Facial Fat and Aging
Facial aging isn’t just about skin sagging – it’s more about the changes happening beneath the surface. Over time, deep fat compartments, like those in the medial cheek and under the eyes, lose volume, while superficial compartments may shift or even expand. This combination creates sagging as the underlying support diminishes, causing tissues above to drop and form noticeable folds or hollows. These changes highlight why addressing facial aging requires precise, informed techniques.
The Importance of Expert Guidance
Understanding how facial fat compartments change with age is key to effective rejuvenation. Restoring volume in a way that looks natural demands a deep knowledge of facial anatomy and accurate filler placement.

By focusing on your unique facial structure and aging pattern, they achieve results that feel harmonious and natural, ensuring you look like the best version of yourself.
FAQs
As we age, the fat compartments beneath our skin undergo changes that can lead to a saggy appearance, even if the skin itself isn’t particularly loose. Facial fat pads tend to shrink and lose volume over time, which diminishes the structural support that helps keep the skin firm. On top of that, bone loss in the facial skeleton further contributes to drooping and hollowing, creating a more aged look even when the skin remains fairly tight.
As we grow older, fat loss tends to happen first in the cheeks, midface, and around the mouth, including areas like the nasolabial folds and malar eminence. This gradual shift often leads to a more hollowed look, giving the face an aged appearance over time.
Providers decide where to place fillers by carefully evaluating how facial fat compartments shift with age. They rely on a detailed understanding of facial anatomy and how soft tissues interact to restore volume in specific areas. This approach helps create balanced and natural-looking outcomes.
