Why do faces get wider with age? Unpacking the science of facial changes

4 min read

According to the National Institutes of Health, age-related bone changes are a significant factor in how faces change over time, leading to a wider appearance in many individuals. We delve into the science behind this phenomenon and address the common question: why do faces get wider with age?

Quick Summary

Facial widening with age is not simply due to weight gain but is primarily caused by a complex interplay of skeletal remodeling, shifting fat pads, and changes in skin elasticity, which collectively alter the face's structure and contours over time.

Key Points

  • Skeletal Remodeling: Bone resorption in the face, particularly the jaw and midface, is a primary cause of facial widening over time, altering the underlying support structure.

  • Fat Pad Migration: Youthful facial fat pads lose volume and shift downward with age, creating a heavier, wider appearance in the lower half of the face.

  • Collagen and Elastin Loss: Decreased skin elasticity due to less collagen and elastin production causes skin to sag, leading to jowls that make the jawline look wider.

  • Mandibular Changes: The jawbone's angle can increase and change shape, contributing directly to a squarer and wider lower facial contour as part of the aging process.

  • Gravity's Role: Gravity exacerbates the effects of fat pad migration and skin laxity, pulling tissues downward and further contributing to facial widening.

  • Lifestyle Impact: Factors like sun exposure, smoking, and significant weight changes can accelerate the natural aging process and its impact on facial shape.

The multi-layered changes of facial aging

Facial aging is a comprehensive process that affects more than just the skin's surface. It involves a cascade of changes in the underlying structures of the face, including the bones, muscles, and fat. While wrinkles and sagging skin are the most visible signs, the deeper, structural shifts are what truly change the overall shape and width of the face, leading to that distinct widening effect many people notice in their later years.

Bone loss and skeletal remodeling

One of the most profound and often overlooked reasons for facial changes is bone resorption, or bone loss. Just as bone density decreases elsewhere in the body with age, the bones of the face also undergo significant remodeling. The facial skeleton, which provides the foundational support for all the overlying soft tissues, gradually loses volume and changes shape. This process contributes to a less defined jawline, a retruding chin, and larger eye sockets. The jawbone, or mandible, is particularly affected, with studies showing an increase in the mandibular angle and a widening of the lower facial third in older adults.

The shifting foundations: How facial bones change

The most noticeable bony changes that contribute to a wider face include:

  • Mandibular remodeling: The jawbone reshapes, often leading to a more square or wider appearance at the bottom of the face.
  • Orbital enlargement: The eye sockets become larger, making the eyes appear more sunken and altering the overall facial contour.
  • Midface volume loss: The bones around the nose and cheeks experience resorption, which reduces the structural support for the mid-cheek fat pads.

The descent and redistribution of facial fat

When we are young, facial fat is evenly distributed in distinct, high-volume pads that give the face a plump, inverted-triangle shape. With age, this changes dramatically. The fat pads lose volume and, due to gravity and a loss of structural support, they begin to slide downward. This downward migration results in hollowing in the cheeks and under the eyes, while creating new volume and fullness in the lower face, near the jawline and chin. The accumulation of migrated fat and the general tendency for some to gain weight as they get older exacerbates this effect, contributing to a wider, heavier-looking jawline.

Loss of collagen and elastin

Collagen and elastin are the proteins responsible for the skin's firmness, elasticity, and youthful bounce. Over time, their production slows down, and existing fibers degrade due to sun exposure, genetics, and other environmental factors. This loss of elasticity means the skin is less able to resist the pull of gravity, and it begins to sag and lose its tight, smooth appearance. This lax skin, combined with the shifting fat pads, can create jowls and a less defined neck and jawline, all of which add to the perception of a wider, heavier lower face.

Comparison: How facial structures change with age

Facial Feature Youthful Appearance Aging Appearance
Facial Shape Inverted triangle (wide cheeks, narrow jaw) More rectangular or square (wider lower face)
Bone Structure Strong, defined facial skeleton; plump cheekbones Resorbed bone; enlarged eye sockets; reduced midface volume
Fat Distribution Evenly distributed, high-volume fat pads Fat pads descend and lose volume; new fat collects in lower face
Skin Elasticity High levels of collagen and elastin; firm and taut Reduced collagen and elastin; sagging skin and jowls
Jawline Tightly defined, sharp angle Wider, less defined; more jowly

Lifestyle and environmental factors

While genetics and natural aging are the primary drivers, several lifestyle and environmental factors can influence the rate and extent of facial widening. Chronic sun exposure accelerates collagen breakdown, leading to premature sagging. Smoking also damages skin and connective tissues, while significant weight fluctuations can repeatedly stretch and strain facial skin. Maintaining a healthy weight and a consistent skincare routine with SPF can help mitigate some of these effects.

Can anything be done to address facial widening?

For those concerned about facial widening, various approaches can help. Non-invasive treatments like dermal fillers can restore lost volume in the midface, lifting the cheeks and reducing the appearance of jowls. Radiofrequency and microneedling treatments can stimulate collagen production, improving skin tightness. For more significant changes, cosmetic procedures or surgery may be considered. Consulting with a dermatologist or plastic surgeon can provide personalized recommendations based on your specific facial structure and goals.

Conclusion: Understanding the natural progression

Ultimately, facial widening is a normal and natural part of the aging process, a culmination of bone resorption, fat pad migration, and reduced skin elasticity. It's a testament to the fact that aging affects us from the inside out, not just the skin's surface. Understanding this process can help you appreciate your body's journey and make informed decisions about how you choose to age gracefully.

Frequently Asked Questions

While some degree of facial change is a normal part of aging, the extent varies based on genetics, lifestyle, and environmental factors. Proper skincare, a healthy diet, and sun protection can help manage and slow down the process.

While weight gain can certainly add fullness to the face, the widening is also a result of deeper, structural changes like bone resorption and shifting fat pads, which occur regardless of weight.

While you can't stop the natural aging process, maintaining a stable, healthy weight, protecting your skin from the sun, and using quality skincare can help. Cosmetic treatments can also address specific concerns.

Facial widening from aging involves structural changes like bone and fat shifting, often resulting in hollowing in some areas and fullness in others. Widening from weight gain is a more uniform increase in fat volume across the face.

Facial exercises are generally not effective at preventing or reversing structural changes like bone resorption or fat pad migration. While some believe they can tone facial muscles, the primary causes are deeper than muscular.

Yes, genetic and ethnic differences can influence how facial structures change over time. Some ethnicities may have stronger bone structures that resist changes for longer, while others may be more prone to specific types of fat migration or bone loss.

Changes typically become more noticeable in your 40s and 50s, as the cumulative effects of bone resorption, fat migration, and collagen loss become more apparent. However, the process begins much earlier and progresses gradually.
