Why do older people get jowls? Unveiling the Causes of a Sagging Jawline

4 min read

Starting in your early 20s, collagen production in the skin decreases by about 1-1.5% annually, a key reason why older people get jowls. This natural process, combined with other biological factors, leads to the noticeable sagging of the lower face.

Quick Summary

Jowls are a result of age-related changes, including the natural breakdown of skin-firming proteins like collagen and elastin, combined with the downward pull of gravity on facial fat pads and weakening muscles and bone structure over time.

Key Points

  • Collagen and Elastin Loss: The natural decrease and breakdown of collagen and elastin fibers are primary drivers of sagging skin.

  • Gravity and Fat Shift: The constant pull of gravity, combined with the downward migration of facial fat pads, contributes to the formation of jowls.

  • Weakened Structure: The weakening of facial muscles, ligaments, and underlying bone structure reduces overall support for the lower face.

  • Lifestyle Impact: Sun damage, smoking, and rapid weight loss can all accelerate the aging process and worsen the appearance of jowls.

  • Treatment Options: Management options range from preventative lifestyle habits to non-invasive treatments like fillers and surgical procedures like facelifts.

  • Genetics Play a Role: Your genetic predisposition can influence how early and how prominently jowls may develop.

The Fundamental Science of Facial Aging

As the body ages, a cascade of biological changes takes place, affecting the skin's structure and the underlying facial support system. These changes are the primary reasons why older people get jowls, and they involve more than just skin laxity.

Loss of Skin Elasticity and Collagen

Elastin and collagen are the essential proteins that provide skin with its youthful firmness and flexibility. As we age, our bodies produce less of these proteins, and what remains becomes damaged and less effective. Elastin allows the skin to 'snap back' after being stretched, while collagen provides the underlying structure. Without this robust network, the skin becomes thinner, drier, and begins to lose its ability to resist the constant downward pull of gravity.

Redistribution of Facial Fat

A youthful face is characterized by a full, rounded appearance, thanks to strategically placed fat pads that provide support and volume. Over time, these fat pads, especially the malar fat pad in the cheeks, shrink and migrate downward. This loss of volume in the mid-face removes support from the lower cheeks, causing the skin to collect and sag along the jawline, forming jowls.

Weakening of Facial Muscles and Ligaments

The SMAS (Superficial Musculo-Aponeurotic System) is a layer of muscle and connective tissue that acts as a hammock, supporting the soft tissues of the face. With age, this system loses its tone and elasticity. The ligaments that anchor facial tissues to the bone also loosen, allowing the entire facial structure to descend and sag. This weakening support system is a significant contributor to the prominence of jowls.

Bone Resorption

While less commonly discussed, changes to the facial skeleton play a crucial role in the aging process. Over time, the facial bones, including the jawbone and cheekbones, experience resorption—a loss of bone density and volume. This reduction in the underlying bony structure removes the foundation that supports the overlying soft tissues, exacerbating the appearance of sagging and jowl formation.

Lifestyle and Environmental Contributors

While aging is the main driver, external factors can significantly accelerate the development of jowls.

  • Sun Damage: Exposure to ultraviolet (UV) radiation from the sun is a primary culprit for premature aging. UV rays break down collagen and elastin fibers at a much faster rate, causing skin to lose its elasticity and firmness earlier than it would otherwise.
  • Smoking: The chemicals in cigarette smoke damage skin tissue and restrict blood flow, depriving the skin of vital nutrients and oxygen. This accelerates collagen and elastin breakdown, leading to earlier and more pronounced jowling.
  • Rapid Weight Fluctuations: Gaining weight stretches the skin. If that weight is lost quickly, the stretched-out skin may not have enough time or elasticity to retract, leaving behind excess, sagging skin. This can be a factor for younger people as well.
  • Genetics: Your family history plays a role in how your face ages. If your parents or grandparents had prominent jowls, you are genetically more predisposed to developing them as well.
  • Poor Posture and Tech Neck: Regularly looking down at a smartphone or other device can cause the neck muscles to weaken and the skin to bunch and fold. This constant downward pressure over time can contribute to the formation of jowls and deep neck creases.

A Comparison of Treatment Options for Jowls

To address jowls, many people explore both surgical and non-surgical options. The right choice depends on the severity of the jowls, desired results, and tolerance for recovery time.

Treatment Type Invasive? Typical Downtime Best For Pros Cons
Surgical Facelift Yes 2-4 weeks Moderate to severe sagging Long-lasting, dramatic results High cost, risks, longer recovery
Surgical Neck Lift Yes 1-2 weeks Sagging jawline and neck Can provide significant contouring Cost, risks, shorter recovery than facelift
Dermal Fillers No Minimal Mild to moderate sagging Immediate results, low risk Not permanent, requires repeat treatments
Ultherapy (Ultrasound) No Minimal Mild to moderate sagging Non-invasive, gradual results Results vary, not for severe cases
Radiofrequency (e.g., Thermage) No Minimal Mild to moderate sagging Stimulates collagen, minimal risk Results are subtle, multiple sessions needed
Thread Lift Minimally Several days Mild to moderate sagging Quick procedure, minimal downtime Results are temporary compared to surgery

What Can You Do to Manage Jowls?

Managing the appearance of jowls can involve both preventative measures and corrective treatments. For those concerned about early development, lifestyle adjustments are key.

  1. Protect Your Skin: Daily use of sunscreen is the most effective way to protect against UV damage, which is a major accelerator of skin aging. Avoid smoking, as it severely impacts skin health.
  2. Maintain a Stable Weight: Extreme weight fluctuations can strain the skin. Maintaining a stable, healthy weight reduces unnecessary stretching of the skin.
  3. Practice Good Posture: Be mindful of your posture, especially when using electronic devices. Hold your head high to avoid straining the neck and jawline muscles, preventing the infamous “tech neck.”
  4. Consider At-Home Solutions: Over-the-counter creams with retinol or peptides can help boost collagen production over time. While not as effective as professional treatments, they can support skin health. Consistent facial exercises, or 'face yoga,' may also offer subtle benefits by strengthening muscles.
  5. Seek Professional Advice: For those seeking more significant results, consulting a dermatologist or cosmetic surgeon is the best course of action. They can assess your specific situation and recommend the most suitable treatment, from fillers to surgical options.

Conclusion

Understanding why older people get jowls involves recognizing the complex interplay of natural aging processes. The combination of declining collagen and elastin, shifting fat pads, weakening muscles, and underlying bone changes all contribute to the sagging jawline. While this is an unavoidable aspect of aging, the rate and severity can be influenced by lifestyle factors. With a range of non-invasive and surgical options available, addressing jowls is possible for those seeking to restore a more defined jawline and youthful contour.

Frequently Asked Questions

You cannot prevent jowls entirely, as they are a natural part of the aging process. However, you can significantly slow their development by protecting your skin from the sun, avoiding smoking, and maintaining a healthy lifestyle.

Facial exercises may help tone the underlying muscles, but their effect on reversing established jowls is typically subtle. Consistent practice can support muscle health, but results are not as dramatic as clinical treatments.

For severe jowls, surgical options like a facelift or neck lift are often considered the gold standard. These procedures can effectively remove excess skin and tighten the underlying structures for a significant, long-lasting improvement.

Yes, rapid or significant weight loss can sometimes make jowls more noticeable. When a person gains weight, their skin stretches. If they lose weight quickly, the skin may not retract fully, resulting in sagging that is more visible.

No, jowls are not considered a medical health risk. They are a cosmetic concern related to the natural aging process. However, if you are concerned, a dermatologist can discuss treatment options.

UV rays from the sun damage the collagen and elastin fibers in your skin. This damage causes these essential structural proteins to break down at a faster rate, accelerating the loss of skin elasticity and contributing to sagging.

Yes, it is possible for younger people to develop jowls due to factors such as genetic predisposition, significant weight loss, or early collagen loss. Genetics can play a large role in how and when facial aging becomes apparent.
