Everyone wants that razor-sharp look. You know the one. That chiseled, "cut glass" silhouette that seems to dominate every fitness influencer’s profile. It’s led to a massive explosion in people searching for jawline exercises before and after results to see if they can replicate that look without a surgeon's scalpel. But let's be real for a second. There is a ton of absolute nonsense circulating on TikTok and YouTube about what a few face flexes can actually do for your bone structure.
I’ve spent years looking at facial anatomy and how the masseter muscle interacts with the skin. Honestly, the results people post online are often a mix of lighting, weight loss, and—let’s be blunt—blatant Photoshop. That doesn't mean facial exercise is a total scam. It just means we need to talk about what’s actually happening under the skin.
What Really Happens in Jawline Exercises Before and After Photos
If you scroll through a "mewing" forum, you’ll see some jaw-dropping transformations. But look closer. Notice how the lighting in the "after" photo is always more dramatic? The shadows are deeper. The person usually lost ten pounds. This is the first thing you have to understand about jawline exercises before and after comparisons: fat loss is the real hero in 90% of these cases.
The human face stores fat in specific compartments. When you lower your overall body fat percentage, the submental fat (the stuff under your chin) is often some of the first to go for many people. Suddenly, the mandible—your jawbone—becomes visible. The "exercise" didn't grow the bone; it just stopped hiding it.
However, there is a muscle component. Your masseter muscles are among the strongest in your body relative to their size. They are what you use to chew. Like any muscle, if you work them out, they can hypertrophy. This means they get bigger. For some people, a larger masseter creates a wider, more "masculine" or square jaw shape. For others, it just makes them look like they have a toothache or leads to TMJ issues.
The Role of Mewing and Tongue Posture
Dr. John Mew, the controversial figure behind the "mewing" craze, suggested that resting your tongue against the roof of your mouth could reshape your maxilla over time. While the orthodontic community is largely skeptical about adults changing their bone structure this way, there is a mechanical truth to it. When you press your tongue up, you instantly tighten the muscles in the floor of the mouth.

Try it right now. Look in the mirror and swallow, then hold that tongue position. Your double chin disappears. That’s a "before and after" that happens in three seconds. But is it permanent? Probably not without years of consistent posture, and even then, the science is shaky on permanent bone remodeling in adults.
The Most Common Exercises People Try
Most people gravitate toward a few specific movements. One is the "Lion Pose" from yoga, where you open your mouth wide and stick out your tongue. Another is the "Chin Tuck," where you pull your head back to strengthen the deep neck flexors.
Then there are the jaw exercisers—those little rubber cubes you bite down on. These are the most dangerous. Why? Because your jaw isn't designed to chew hundreds of pounds of resistance for "reps." I've seen people end up with severe jaw clicking and headaches because they treated their face like it was leg day at the gym.
- The Chin Lift: You look at the ceiling and pout your lips. It feels like a stretch. It's mostly just stretching the platysma muscle.
- The Jaw Jut: Sliding the lower jaw forward and holding it. It creates a temporary pump in the muscles around the ears.
- Neck Curls: Lying on your back and lifting your head. This actually works the muscles that support the jawline, which can help with "tech neck."
Understanding the Limitations of Facial Anatomy
We have to talk about genetics. Some people are born with a high "gonial angle." This means their jawbone naturally sits in a way that looks defined even if they aren't in peak shape. If your mandible is naturally recessed (a "weak chin"), no amount of chewing gum is going to turn you into Henry Cavill.

A study published in the Aesthetic Surgery Journal looked at facial aging and muscle volume. It found that while facial exercises might improve skin elasticity and muscle tone in middle-aged women, the changes were subtle. They weren't structural. You aren't moving the bone. You’re just toning the "meat" on top of the bone.
The Problem with "Jawline Gum"
Marketing is a powerful thing. There are brands selling "hard gum" specifically for jawline gains. While it does provide more resistance than a stick of Orbit, the risk-to-reward ratio is skewed. Overdeveloping the masseter can actually lead to a "bulky" look that isn't always aesthetically pleasing. Worse, it can trigger bruxism (teeth grinding) at night. If you’re waking up with a sore face, the jawline exercises before and after results you're getting are actually just inflammation.
Real-World Factors That Change the Jawline
If you want a real transformation, you have to look at the holistic picture. It's rarely just about the exercises.
- Hydration and Sodium: If you eat a high-sodium meal and don't drink water, your face puffs up. You lose your jawline. In many "before and after" shots, the person simply stopped eating processed ramen and started drinking a gallon of water a day.
- Posture: "Tech neck" is the enemy of the jawline. When your head leans forward to look at a phone, the skin under your chin bunches up. Correcting your spinal alignment pulls that skin taut.
- Sleep: Lack of sleep leads to systemic inflammation and "moon face."
- Professional Treatments: We can't ignore that some people claiming "jawline exercises" actually got Kybella or chin filler. It’s a dirty secret in the transformation community.
How to Safely Improve Your Jawline Definition
If you still want to try it, do it safely. Don't buy the heavy-duty bite blocks. Instead, focus on tongue posture and general fitness.
Start by bringing your teeth together lightly. Place your entire tongue—not just the tip—against the roof of your mouth. Breathe through your nose. This is the foundation of a "functional" jawline. It prevents the mouth-breathing posture that often leads to a recessed chin look over time.
Focus on your neck muscles. The platysma is a broad sheet of muscle that runs from your jaw down to your chest. Keeping this muscle toned can help prevent the "turkey neck" look. You can do this by tightening the muscles in your neck until the tendons stand out, then relaxing. Just don't overdo it. Ten repetitions a day is plenty.

Monitoring Your Progress
If you’re tracking your own jawline exercises before and after, take your photos in the same spot at the same time of day. Use natural side-lighting. This will give you an honest look at whether your efforts are paying off. Don't expect a new face in two weeks. Muscle hypertrophy takes months. Skin tightening takes even longer.
Actionable Steps for a Better Profile
Instead of looking for a magic exercise, try these evidence-based shifts:
- Reduce Body Fat: This is the only guaranteed way to make your jawline more prominent. Focus on a slight caloric deficit and strength training.
- Correct Your Tongue Posture: Practice keeping your tongue on the roof of your mouth throughout the day. It’s a habit, not an exercise.
- Fix Your Head Position: Pull your shoulders back and align your ears over your shoulders. This instantly tightens the submental area.
- Lymphatic Drainage: Use a Gua Sha or just your fingers to massage the jawline from the chin toward the ears. This helps move excess fluid (edema) that causes puffiness.
- Consult a Professional: If you have a recessed jaw that causes breathing issues, see an orthodontist or a maxillofacial surgeon. Sometimes the issue is functional, not just cosmetic.
The truth about jawline exercises before and after is that they work best as a supplement to a healthy lifestyle, not a replacement for it. You can't out-chew a high-body-fat percentage or poor genetics, but you can definitely maximize what you’ve been given by staying lean and keeping your posture in check.
