You’ve probably seen the ads. Someone with a perfectly chiseled jawline is chewing on a silicone block or making exaggerated fish faces at their phone camera. They claim a specific double chin removal exercise transformed their profile in exactly two weeks. Honestly? It's usually a lie. Or at least, it’s a massive oversimplification of how human anatomy actually functions.
We need to talk about submental fat. That’s the clinical term for the padding under your jaw. Everyone has some. But when it becomes prominent enough to affect your confidence, the instinct is to "spot treat" it with movement. The reality is that you can’t exactly "burn" fat from one specific spot by moving the muscle underneath it. If that worked, people who talk a lot would all have thin faces. Still, there is a nuance here that most fitness influencers miss. While you can't target fat loss, you can improve muscle tone and posture, which changes how that area looks to the world.
The Myth of Spot Reduction
Let's get the bad news out of the way first. Science—real, peer-reviewed science—has debunked spot reduction over and over again. A 2013 study published in the Journal of Strength and Conditioning Research looked at whether local exercise could reduce fat in a specific area. Participants did thousands of leg presses on just one leg. The result? They lost fat, but they lost it everywhere, not just in the worked leg.
The same applies to your face. Doing a double chin removal exercise won't magically melt the lipids stored under your chin. Fat loss happens through a caloric deficit, where your body pulls energy from wherever it wants, usually determined by your genetics. Some people lose it in their face first; others are stuck with "baby face" until they reach a very low body fat percentage.
So, why do people swear by these exercises?
Because of the platysma. This is a broad, thin sheet of muscle that runs from your collarbone up to your jaw. When this muscle is weak or saggy, the skin and fat over it have no structural support. Strengthening it won't make the fat vanish, but it can "tighten the sling," making the jawline appear more defined. It's about architecture, not just weight.

Three Exercises That Actually Target the Right Muscles
If you're going to do this, do it right. Don't just waggle your jaw around. You want to focus on the hyoid muscles and the platysma.
The Tongue Press (The Hyoid Lift)
This one looks ridiculous, but it hits the muscles directly under the chin. Sit up straight. Tilt your head back so you're looking at the ceiling. Now, press your tongue flat against the roof of your mouth. While keeping the tongue pressed, lower your chin toward your chest as much as possible without rounding your back. You should feel a significant "pull" in the front of your neck. Relax and repeat.
The Pout and Tilt
Stick your lower lip out as far as you can to form a pout (think "grumpy toddler"). Hold that contraction in your chin. While keeping the lip out, use your neck muscles to lower your chin toward your chest. Hold for two seconds, then return to neutral. This specifically engages the mentalis and the upper portion of the platysma.
The Jaw Jut
Tilt your head back and look at the ceiling. Push your lower jaw forward until you feel a stretch under the chin. Hold it. It’s simple, but it’s effective for engaging the superficial cervical fascia.
The Posture Connection: "Tech Neck" is Real
Sometimes, what looks like a double chin is actually just bad skeletal alignment. We spend hours hunched over iPhones and MacBooks. This creates "forward head posture." When your head stays forward of your shoulders, the skin under your jaw bunches up. It creates a fold where there might not even be much fat.

Dr. Eric Berg, a popular health educator, often points out that correcting the "hunch" in the upper back can instantly improve the appearance of the jawline. If your shoulders are rounded, your neck muscles are chronically overstretched and weak.
Try this: stand against a wall with your heels, butt, and shoulder blades touching the surface. Now, try to touch the back of your head to the wall without tilting your chin up. It’s harder than it looks. This "tucking" motion strengthens the deep neck flexors. Do this consistently, and your head will sit further back on your spine, pulling the skin under your chin taut. It’s a double chin removal exercise disguised as a posture fix.
Is it Fat or is it Lymph?
Here is something most people overlook: puffiness. The area under the jaw is home to several lymph nodes. If your lymphatic system is sluggish due to high sodium intake, lack of sleep, or chronic inflammation, you’ll store fluid there. This is "water weight" for your face.
This is where "face yoga" practitioners might actually have a point, though not for the reasons they think. The gentle stroking motions used in lymphatic drainage massages don't "tone" muscles, but they do help move stagnant fluid out of the facial tissues and down toward the thoracic duct. If your double chin seems to fluctuate in size between morning and night, it's likely fluid, not fat.
When Exercise Isn't Enough: The Genetic Factor
We have to be honest. For some people, no amount of double chin removal exercise or weight loss will completely eliminate the issue. Submental fullness is often hereditary. You might have a "recessed chin" (micrognathia) where the bone structure of the lower jaw is set further back. Without a strong bony shelf to support the soft tissue, the skin will naturally hang.

In these cases, medical interventions are the only permanent fix. Kybella, for example, is an FDA-approved injectable made of deoxycholic acid. It literally dissolves fat cells. Then there's CoolSculpting, which freezes them. Or the gold standard: submental liposuction. It sounds extreme, but for someone with a genetic predisposition, 20 minutes of surgery does more than 20 years of jaw exercises ever could.
Diet and Inflammation: The Internal Factor
You cannot out-exercise a diet that causes systemic inflammation. High sugar intake leads to glycation, which breaks down collagen and elastin in the skin. When the skin under your chin loses its "snap," it sags. This creates the illusion of more fat than is actually there.
Focusing on a diet rich in vitamin C (for collagen synthesis) and staying hydrated is boring advice, but it's foundational. If you’re dehydrated, your body holds onto water in the weirdest places—including your neck.
Actionable Next Steps for a Sharper Jawline
If you're serious about changing your profile, stop looking for a magic bullet and start a multi-pronged approach:
- Audit Your Posture: Spend five minutes every day doing "wall tucks." Stand against a flat surface and pull your skull back to meet it. This resets your cervical spine and stretches the front of the neck.
- Hydrate and De-puff: Reduce your salt intake for 48 hours and drink three liters of water daily. Use a Gua Sha tool or even just your knuckles to gently stroke from the center of your chin out toward your ears to move lymphatic fluid.
- Perform Targeted Contractions: Incorporate the Tongue Press and Jaw Jut into your morning routine. Do three sets of 15 reps. Consistency is more important than intensity; you're building muscle endurance here.
- Check Your Body Fat Percentage: If you are over a certain body fat threshold (roughly 20% for men, 28% for women), the most effective double chin removal exercise is actually a full-body workout and a caloric deficit.
- Consult a Professional: If you've reached your goal weight and the "pouch" is still there, see a dermatologist to determine if it's a structural issue or stubborn fat that requires cooling or dissolving treatments.
Real progress happens when you stop treating the chin as an isolated part of the body and start treating it as the end-point of your posture, your diet, and your overall muscle tone.
