Have you noticed how some celebrities seem to defy aging, maintaining sharp, defined jawlines well into their 50s and 60s? Watching your own profile lose definition while Hollywood stars like Demi Moore appear to maintain increasingly sculpted features can leave many wondering what their secret really is. However, the stunning jawline transformations we see on red carpets aren’t always the result of good genes or contouring. Modern aesthetic techniques have made it possible for many people to achieve a smooth, defined jawline that enhances facial symmetry and confidence.
The Evolution of Demi Moore’s Striking Profile
Demi Moore, now 62, has become a symbol of ageless beauty in Hollywood. Her recent appearances have sparked speculation and conversation about her remarkably defined jawline and neck area, which many observers note appears more sculpted than it did even a decade ago. While Moore has not publicly confirmed any cosmetic procedures, the noticeable change in her facial contours has led to discussions of possible aesthetic treatments or techniques that could produce similar effects.
Her evolving look reflects a broader trend in how celebrities maintain and enhance their facial contours through both non-surgical and surgical methods designed to achieve natural-looking results.

Understanding Jawline Definition and Age-Related Changes
As we age, several factors contribute to the loss of jawline definition and the growing interest in jawline definition procedures:
Collagen and Elastin Loss
Beginning as early as our 20s, the body’s natural collagen and elastin production slows each year. These proteins are responsible for maintaining skin strength, elasticity, and tightness. As their levels decline, the skin along the jaw and neck becomes thinner, looser, and more prone to sagging. This loss of firmness allows gravity to pull the tissues downward, blurring the once-sharp angle between the jaw and neck.
Gravity and Tissue Descent
The constant downward pull of gravity affects more than just skin; it gradually shifts the fat pads and connective tissue that support the mid and lower face. Over time, these structures slide toward the jawline, creating jowls and a heaviness along the lower cheeks. The once-smooth contour becomes uneven, with the skin folding near the corners of the mouth and jaw.
Bone Resorption and Structural Changes
Facial bones also change with age. The mandible (jawbone) slowly loses volume and definition, especially near the chin and jaw angle. This bone resorption weakens the foundation that supports soft tissue, contributing to sagging skin and a softer jawline appearance. A smaller bone framework means there’s less support for the overlying fat and muscle, amplifying signs of lower-face aging.
Fat Redistribution and Volume Loss
Youthful faces have well-distributed fat that maintains smooth transitions between the cheeks, jawline, and neck. As we age, this fat redistributes and diminishes, particularly in the midface and chin area. The resulting loss of volume causes hollowness above the jawline while excess fat can accumulate below it, producing the appearance of a double chin or fullness beneath the jaw.
Muscle Changes and Skin Laxity
The platysma muscle, which extends from the collarbone to the jawline, becomes more prominent and lax with age. This leads to visible vertical neck bands and a loss of tone along the jaw. Combined with skin laxity, it contributes to the “turkey neck” effect and blurs the distinction between the face and neck.
Lifestyle and Environmental Factors
External influences such as sun exposure, weight fluctuations, poor posture (“tech neck”), dehydration, and smoking accelerate these age-related changes. UV damage breaks down collagen faster, while repeated downward head posture deepens folds under the chin. These habits compound natural aging and make the jawline appear less sculpted earlier in life.
Since the jawline serves as the structural anchor of the lower face, its loss can dramatically alter facial balance and perceived youthfulness. Modern aesthetic treatments, both surgical and non-surgical, can target these underlying causes by restoring volume, tightening skin, and reestablishing the natural contours that define a youthful, confident appearance.

Popular Chin Enhancement Procedures for Jawline Refinement
Chin Implants
Custom-sized silicone implants are used to increase chin projection and improve facial balance. These can be helpful for a recessed chin, an undefined jawline, or the appearance of a larger nose. After sizing and shape are selected during consultation, the implant is placed through a small incision either inside the mouth or under the chin and positioned securely in front of the jawbone.
The procedure is performed under general anesthesia. Recovery typically involves temporary swelling and a short soft-food diet. Implants are selected to harmonize with the entire face so the profile looks proportionate.
Genioplasty
Genioplasty modifies the chin bone itself to reduce, reshape, or advance the structure when implants alone can’t achieve the goal. An incision is made inside the mouth (or beneath the chin) to access the bone. The surgeon makes a controlled cut, repositions the bone segment to the planned projection, and secures it with a titanium plate.
It can help with improved balance between nose and chin and a permanent, tailored change to height, width, or projection.
Non-Surgical Chin Treatments
For individuals noticing excess fullness beneath the chin, a non-surgical treatment like KYBELLA offers a convenient alternative to more invasive options. This injectable procedure utilises a synthetic version of deoxycholic acid, the same molecule our body uses to break down dietary fat, to target and reduce fat cells in the submental (below-chin) region. Sessions typically take about 15–20 minutes, involve minimal downtime, and are customized to your individual goals. While multiple treatments may be needed for optimal results, the relief from unwanted chin-fat can help improve self-confidence by restoring a cleaner, more defined jawline.
Neck Contouring Techniques
Neck Lift Surgery for Dramatic Results
A neck lift, or lower rhytidectomy, addresses loose skin, muscle banding, and excess fat in the neck area. This surgical procedure can dramatically improve the neck-jaw angle, creating the sharp definition that characterizes youthful profiles. The technique involves tightening the platysma muscle and removing excess skin to restore a clean neckline.
Submentoplasty
Submentoplasty is a focused neck-contouring surgery that targets the area directly under the chin (submental region) to reduce a double chin and sharpen the jaw–neck angle. It’s designed to address excess fat, platysma muscle laxity, and early skin sagging beneath the chin, often as a less-extensive alternative to a full neck lift. It can be performed on its own or combined with related techniques to refine the neckline and improve lower-face balance.
Recovery and Results
Recovery and results depend largely on the type of procedure performed. Non-surgical treatments, such as KYBELLA, generally involve minimal downtime. Patients can often resume daily activities within a few days. In contrast, surgical procedures like a neck lift or submentoplasty require a more structured recovery period, often around a few weeks before returning to work and even months for complete healing.
Results also develop on different timelines. Surgical procedures often deliver immediate structural improvement that refines further as swelling resolves over the following months. Non-surgical treatments, however, create progressive changes that become more visible after a series of sessions, with steady enhancement over several weeks.
In terms of longevity, surgical results can last for many years when supported by a healthy lifestyle and proper skincare, while non-surgical approaches benefit from periodic maintenance treatments to preserve contour and definition. Regardless of the method, consistent follow-up and personalized aftercare play important roles in achieving lasting, natural-looking outcomes.

Safety Considerations and Choosing the Right Provider
Any procedure that alters facial structure, whether surgical or non-surgical, requires precision, anatomical understanding, and medical expertise. The jawline, in particular, involves delicate structures such as facial nerves, blood vessels, and muscles that control expression and symmetry. That’s why it’s essential to consider:
- Certification and Surgical Expertise: Always ensure your provider is certified and has experience in facial aesthetics.
- Comprehensive Consultation: A detailed consultation should include a facial analysis, medical history review, and discussion of goals and expectations.
- Realistic Expectations: A skilled provider will help you set realistic expectations about results and recovery. Follow-up appointments, post-procedure instructions, and access to the surgical team for concerns are essential components of safe care.
